The XTREME series combines NanoPro technology with biodegradable surfactants — for streak-free windows from the very first wipe, even in direct sunlight and with hard water.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003eSONAX XTREME wiper fluid\u003c\/strong\u003e is not a single product, but a two-part system for clean windshields: a ready-to-use summer mixture and a 1:100 highly concentrated solution. Both products originate from German SONAX research and rely on the in-house NanoPro technology, which dissolves dirt particles at a molecular level instead of merely moving them around. The result is a level of visibility that you'll search for in vain with conventional wiper fluids from hardware stores — no soapy film, no limescale spots, and no streaks in direct sunlight.\u003c\/p\u003e\n\n\u003cp\u003eAnyone who has ever cleaned their windshield after a long highway drive in the summer and still saw a milky haze in direct sunlight despite ten wipes knows the problem: cheap wiper fluids often only move the dirt around, but don't dissolve it. SONAX developed the XTREME wiper fluid series precisely for this situation — with a formula that chemically decomposes organic dirt and removes mineral residues like limescale or road salt film from the windshield without leaving any traces. And it does so while being biodegradable.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStreak-free from the first wipe.\u003c\/strong\u003e The special surfactant formula leaves no residue on the windshield. Even in direct sunlight or with oncoming traffic at dusk, visibility remains clear — a safety factor that many underestimate. Unlike conventional wiper fluids, you don't need to wipe multiple times until the result is right.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtreme yield thanks to 1:100 concentrate.\u003c\/strong\u003e A compact 250 ml bottle produces up to 25 liters of ready-to-use wiper fluid. This saves space in the trunk, reduces packaging waste, and lowers the cost per tank filling to just a few cents. Over an entire year, the concentrate is significantly more economical than any ready-mix — and yet more powerful.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBiodegradable — without loss of performance.\u003c\/strong\u003e With the XTREME line, SONAX demonstrates that environmental compatibility and cleaning performance are not opposites. The formula is biodegradable according to OECD standards and yet strong enough for dried-on insect residues, tree sap, and pollen film.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e Many drivers pour the concentrate too generously into the wiper fluid reservoir — following the motto \"more is more.\" With SONAX XTREME 1:100, this is counterproductive: over-dosing creates more foam, prolongs drying time, and leaves precisely the streaks you want to avoid. Stick exactly to the 1:100 mixing ratio (10 ml per 1 liter of water) and you'll immediately see the difference — less foam, faster drying, crystal-clear vision.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eNanoPro Technology — What makes SONAX XTREME Wiper Fluid different?\u003c\/h3\u003e\n\n\u003cp\u003eThe decisive difference between the \u003cstrong\u003eXTREME Windscreen Cleaner\u003c\/strong\u003e and an average wiper fluid lies in the formulation. SONAX relies on so-called NanoPro technology for the XTREME line: nano-surfactants penetrate microscopically small dirt particles and detach them from the glass surface before the windshield wiper carries them away. Classic wiper fluids, on the other hand, primarily work mechanically — the wiper pushes the dirt, and the water rinses. For stubborn dirt like dried-on insect residues, tree sap, or pollen film, this is often not enough.\u003c\/p\u003e\n\n\u003cp\u003eThe NanoPro formula dissolves dirt in three phases: First, the surfactants evenly wet the entire windshield surface — even in areas that the wiper doesn't reach perfectly. Then, they penetrate the dirt layer and break the bond between dirt particles and glass. In the third step, the wiper removes the dissolved dirt without just smearing it. This three-step process explains why a single wipe is often sufficient, while conventional wiper fluids require three or four wipes.\u003c\/p\u003e\n\n\u003cp\u003eAnother technical advantage of the XTREME formulation: it is explicitly material-friendly. This means that neither rubber seals on the windshield nor the wiper blades themselves are attacked. Cheap wiper fluids occasionally contain aggressive solvents that make rubber brittle and shorten the lifespan of wiper blades — a hidden cost factor that many drivers only notice when the wipers start streaking after six months. With SONAX XTREME, a good wiper blade will last its full lifespan.\u003c\/p\u003e\n\n\u003cp\u003eWater hardness also plays a role for many wiper fluids: in regions with hard tap water, standard products often leave white limescale spots on the windshield, especially if the wiper fluid dries in the sun. The XTREME formula contains special water softening components that bind limescale in the solution and prevent it from settling on the glass when drying. This is an advantage that is particularly relevant in Southern Germany, Austria, and Switzerland, where water hardness often exceeds 20 °dH.\u003c\/p\u003e\n\n\u003cp\u003eA point rarely mentioned in wiper fluid tests, but relevant in practice: odor development. Cheap wiper fluids often smell sharply of alcohol or chemicals — an odor that gets into the vehicle interior through the ventilation and is particularly unpleasant for sensitive people and children. The XTREME formula uses discreet, quickly evaporating fragrances that are barely noticeable when sprayed. This may seem like a minor detail, but it makes a noticeable difference in driving comfort on a long highway trip with frequent windshield washing.\u003c\/p\u003e\n\n\u003cp\u003eAnother technical detail that will interest detailers and car care enthusiasts: SONAX XTREME wiper fluid leaves no silicone residues on the windshield. This is relevant if you plan to apply a windshield sealant — silicone on the glass prevents the adhesion of sealants and must be painstakingly removed before application. With XTREME wiper fluid, this step is eliminated because the windshield is already ready for sealing after washing.\u003c\/p\u003e\n\n\u003ch3\u003eReady-to-use or Concentrate — Which XTREME Wiper Fluid is right for you?\u003c\/h3\u003e\n\n\u003cp\u003eThe XTREME wiper fluid series consists of two products that address different requirements. Which one is right for you depends on how you use your car and what you value.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\"\u003eXTREME Windscreen Cleaner \"Summer\" ready-to-use\u003c\/a\u003e is the uncomplicated solution: open the canister, pour it into the wiper fluid reservoir, done. No measuring, no mixing, no potential for error. With 3 liters per canister, one filling is enough for several weeks of normal everyday use. The ready-to-use version is perfectly pre-mixed — the surfactant-water ratio is precisely set as SONAX intended for optimal cleaning performance. You are guaranteed full performance without having to dose it yourself.\u003c\/p\u003e\n\n\u003cp\u003eOne scenario where the ready-mix clearly has an advantage: if you rarely refill the tank and the wiper fluid sits in the reservoir for a long time. The ready-to-use version is stably formulated and does not lose cleaning performance even after weeks in the tank. It is also ideal for anyone who simply doesn't want to deal with mixing ratios — open the lid, fill, drive on.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat\"\u003eXTREME Windscreen Cleaner 1:100 Concentrate\u003c\/a\u003e is aimed at drivers who value efficiency and sustainability. 250 ml of concentrate yields up to 25 liters of ready-to-use \u003cstrong\u003ewiper fluid\u003c\/strong\u003e — equivalent to over eight full tank fillings for most vehicles. The compact dosing bottle fits into any glove compartment and is therefore always at hand for travel and longer tours, without taking up space in the trunk.\u003c\/p\u003e\n\n\u003cp\u003eThe cost calculation clearly favors the concentrate: a 250 ml bottle is sufficient for half a year or more with normal driving performance. Compared to ready-mixes, you save not only money but also packaging — instead of eight 3-liter canisters, you use one small bottle. For households with two or three vehicles, this advantage quickly adds up. The only disadvantage: you have to dose it yourself. But with the scale on the SONAX dosing bottle and the simple 1:100 ratio, this is done in a few seconds.\u003c\/p\u003e\n\n\u003cp\u003eBoth variants are formulated exclusively for summer use and do not offer frost protection. For the cold season, it is recommended to switch to a frost-proof wiper fluid with antifreeze — mixed operation with antifreeze from other manufacturers is generally possible, but you only get full XTREME performance with the undiluted SONAX product.\u003c\/p\u003e\n\n\u003ch3\u003eRefilling Wiper Fluid Correctly — Mixing Ratio and Application in Detail\u003c\/h3\u003e\n\n\u003cp\u003eWith \u003cstrong\u003eready-to-use XTREME wiper fluid\u003c\/strong\u003e, application is incredibly simple: open the hood, unscrew the wiper fluid reservoir cap (identifiable by the wiper symbol), pour it in. No dilution, no thinking. Just be careful not to overfill the tank — the mark on the container shows you the maximum. A small practical tip: if the tank still contains remnants of another wiper fluid, that's not a problem. SONAX XTREME is miscible with all common summer wiper fluids. For the best performance, however, we recommend completely filling the tank with XTREME next time.\u003c\/p\u003e\n\n\u003cp\u003eWith the \u003cstrong\u003e1:100 wiper fluid concentrate\u003c\/strong\u003e, the correct mixing ratio is crucial for the result. SONAX specifies 1:100 as the optimal dosage, meaning 10 ml of concentrate per 1 liter of water. In practice, this means: for a typical 3-liter wiper fluid reservoir, about 30 ml of concentrate is sufficient — that's less than a shot glass. SONAX's dosing bottle has a built-in scale that makes measuring easier, and a precise spout that prevents spills.\u003c\/p\u003e\n\n\u003cp\u003eThe correct mixing order makes a difference: first, fill the tank with clear water, then add the concentrate. This way, the solution mixes evenly and you avoid foaming, which can occur if the order is reversed. If you need to refill the tank on the go — for example, at a rest stop — you can also pour the concentrate directly into the half-full tank. The pumping action during windshield washing will then ensure sufficient mixing.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to clean the windows particularly thoroughly before refilling, you can spray on \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenklar-glasreiniger\"\u003eXTREME Windscreen Clear Glass Cleaner\u003c\/a\u003e beforehand to remove old residues of tree sap, insects, or silicone films. This optimizes the performance of the fresh wiper fluid because the NanoPro surfactants work more efficiently on a clean glass surface. In combination with a \u003ca href=\"\/en\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\"\u003eSONAX PROFILINE Microfiber Cloth \"Glass\"\u003c\/a\u003e, you get a result that approaches professional glass cleaning.\u003c\/p\u003e\n\n\u003ch3\u003eSONAX XTREME vs. Standard Wiper Fluid — Honest Assessment\u003c\/h3\u003e\n\n\u003cp\u003eIs a premium \u003cstrong\u003ewiper fluid\u003c\/strong\u003e like SONAX XTREME worth it compared to the 1-euro canister from the gas station? The honest answer: it depends on what's important to you. Standard wiper fluids clean — that's their job, and they do it basically. For a short drive to the supermarket, that's perfectly sufficient. But as soon as you drive longer distances, are driving in direct sunlight, or regularly maintain your vehicle, you will notice the differences.\u003c\/p\u003e\n\n\u003cp\u003eThe most visible difference is seen in direct sunlight: cheap wiper fluids often leave a thin film on the windshield that is invisible in daylight but acts like a milky haze in low sun or with oncoming headlights. This film is caused by inferior surfactants and incompletely dissolved limescale residues. SONAX XTREME avoids this with the NanoPro formula — the windshield is actually clean after wiping, and not just superficially wetted.\u003c\/p\u003e\n\n\u003cp\u003eA second difference concerns material compatibility. Cheap wiper fluids occasionally contain methanol or aggressive solvents that attack rubber seals, make wiper blades brittle, and fade plastic parts around the windshield. SONAX deliberately formulates the XTREME line without such substances — a difference that is not immediately apparent, but becomes visible after a year when seals and wipers are still in good condition.\u003c\/p\u003e\n\n\u003cp\u003eThose who have also applied a \u003ca href=\"\/en\/products\/sonax-profiline-ceramiccoating-cc-glass-scheibenversiegelung\"\u003eSONAX CeramicCoating CC Glass Sealant\u003c\/a\u003e benefit particularly: the XTREME wiper fluid works even more efficiently on the sealed surface because dirt adheres less and water beads off faster. The combination of ceramic sealant and XTREME wiper fluid creates a lotus effect that, in rain, means you hardly need the windshield wipers at speeds above about 60 km\/h. Important: not every wiper fluid is compatible with sealants — aggressive formulations can dissolve coatings. SONAX XTREME is explicitly coating-compatible.\u003c\/p\u003e\n\n\u003cp\u003eCompared to other premium wiper fluids, SONAX XTREME positions itself in the upper mid-range: qualitatively on par with special products from manufacturers like Liqui Moly or Nigrin, but significantly more economical in terms of price thanks to the 1:100 concentrate. If you use the concentrate, you pay less per liter of ready-to-use wiper fluid than with most ready-mixes — even the cheap ones from the hardware store.\u003c\/p\u003e\n\n\u003cp\u003eOne aspect often forgotten in price comparisons: follow-up costs. If you use an aggressive, cheap wiper fluid, you'll replace the wiper blades more often — brittle rubber causes streaks, and new wipers cost between 15 and 40 euros depending on the vehicle. SONAX XTREME demonstrably protects wiper blades, which reduces these follow-up costs. If you add up wiper fluid costs and wiper blade lifespan, the XTREME series is in most cases the more economical overall solution — even if the liter price seems higher at first glance.\u003c\/p\u003e\n\n\u003cp\u003eEven compared to so-called \"premium\" wiper fluids from gas station private labels, SONAX XTREME performs well. These products are often more expensive than the hardware store variants, but rarely offer documented technology like NanoPro. They clean better than entry-level products but do not achieve the residue-free finish and material compatibility that SONAX guarantees with the XTREME line. Anyone who has made the direct comparison — one half of the windshield with standard wiper fluid, the other with XTREME — will immediately see the difference in direct sunlight.\u003c\/p\u003e\n\n\u003ch3\u003eFor whom is SONAX XTREME Wiper Fluid the right choice?\u003c\/h3\u003e\n\n\u003cp\u003eThe XTREME \u003cstrong\u003ewiper fluid\u003c\/strong\u003e series is aimed at drivers who take clear visibility seriously as a safety factor and at the same time value economy and environmental compatibility. You don't have to be a detailing professional to benefit from the series — on the contrary: everyday drivers in particular notice the difference most clearly because they have often used standard wiper fluids for years and have accepted the milky layer on the windshield as normal.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eready-to-use summer wiper fluid\u003c\/strong\u003e is particularly suitable for drivers who prefer an uncomplicated solution without mixing and dosing. It's the right choice if you fill the tank once a month and don't want to worry about it any further. The ready-mix is also ideal for infrequent drivers and short distances, as you don't have to mix a minimum amount and the 3-liter canister in the cellar won't go bad.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e1:100 concentrate\u003c\/strong\u003e is the smart choice for frequent drivers, families with multiple cars, and anyone who wants to reduce long-term costs and packaging waste. A single 250 ml bottle replaces eight canisters of ready-mix — this saves storage space in the garage and dozens of plastic canisters per year. Commuters who drive 50 kilometers or more daily will particularly appreciate the concentrate: the costs per tank filling are in the single-digit cent range.\u003c\/p\u003e\n\n\u003cp\u003eIn combination with XTREME Windscreen Clear as an intensive cleaner for manual window cleaning, you have a complete system for streak-free windows — from a quick wiper fluid pass at a traffic light to thorough hand care on the weekend. And if you regularly detail your vehicle and value a well-maintained appearance, XTREME wiper fluid is the logical component in the overall concept: it protects sealants, spares materials, and delivers a result that matches the rest of your vehicle care.\u003c\/p\u003e\n\n\u003cp\u003eFleet managers and operators of vehicle pools also benefit: the 1:100 concentrate significantly simplifies logistics because only small dosing bottles need to be stored and distributed instead of heavy 3-liter canisters. For a fleet of 20 vehicles, this saves hundreds of liters of packaging volume per year and simplifies reordering. The consistently high quality of the XTREME formulation also means that all vehicles deliver the same cleaning result regardless of location or local water hardness — an advantage for companies with distributed locations across Germany.\u003c\/p\u003e","products":[{"product_id":"sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat","title":"XTREME Windscreen Cleaner 1:100 Washer Fluid Concentrate","description":"\u003ch2\u003eUp to 25 Liters of Windshield Wiper Fluid from One Bottle — SONAX XTREME Windscreen Cleaner 1:100 as a Super Concentrate\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat makes SONAX's super concentrate wiper fluid so special?

The \u003cstrong\u003eSONAX XTREME Windscreen Cleaner 1:100\u003c\/strong\u003e solves this problem with unusual efficiency: The super concentrate in the practical 250ml bottle is diluted at a ratio of 1:100 — this corresponds to 2.5 ml per 250 ml of water, or conversely: one bottle is enough for 25 liters of wiper fluid. This significantly saves space, weight, and costs compared to classic ready-to-use wiper fluids.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:100 Concentration Ratio — One Bottle, Up to 25 Liters.\u003c\/strong\u003e The extreme concentration ratio is the central advantage of this product. Compared to a 5-liter canister of ready-to-use wiper fluid, the 1:100 concentrate requires only a fraction of the storage volume and transport weight.

A dirty windshield reduces the driver's reaction time, as contours and obstacles in the dirty film are recognized later. This is especially true in rain, when insect remains and road dust combine with moisture and are spread by the windshield wipers into a greasy film instead of being cleanly wiped away. A powerful windshield washer fluid that is already active in the windshield washer reservoir prevents exactly this effect: It dissolves dirt before wiping and allows the windshield wiper a clean, streak-free wiping path — with every wipe.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1 Pro Tip:\u003c\/strong\u003e For optimal results, mix the Windscreen Cleaner 1:100 directly in the windshield washer reservoir: Fill the tank with tap water and then add the appropriate amount of concentrate — for a typical 3-liter tank, that's 30 ml of concentrate. For stubborn insect residues on the front windshield, the concentration can be moderately increased (1:50 to 1:30) — more cleaning agent will then be active per wipe when the windshield wiper is in spray mode. The 250ml bottle is perfect for carrying in the trunk when traveling, as it takes up little space and provides enough supply for long distances.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSuper Concentrate Technology of Windscreen Cleaner 1:100 — Mode of Action and Formulation Logic\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME Windscreen Cleaner 1:100\u003c\/strong\u003e uses a highly concentrated surfactant and cleaning agent formulation that, when diluted with water at a ratio of 1:100, results in a fully functional wiper fluid. The concentration ratio is not arbitrary: The active ingredients are dosed so high that after dilution to 1:100, there is still enough surfactant, dewatering agent, and cleaning substance present to fully act on the windshield and evaporate with low residue after drying.\u003c\/p\u003e\n\n\u003cp\u003eThe streak-free finish is achieved through the targeted use of dewatering agents (surfactants with hydrophobic properties) that distribute the water evenly and allow it to run off in a controlled manner. Without these additives, the water would remain in drops and puddles on the windshield during wiping and leave streaks when drying. The dewatering agents in the Windscreen Cleaner 1:100 ensure that the wash water is thinly distributed over the entire windshield surface and dries in a uniform, streak-free layer.\u003c\/p\u003e\n\n\u003cp\u003eThe super concentrate logic follows a clear principle of product development: The higher the concentration ratio, the lower the proportion of water in the finished product, the smaller the packaging, and the lower the ecological footprint of transport. With the 1:100 concentrate, SONAX is relying on a format that is already established in other cleaning agent categories but is still little used in the wiper fluid sector — a clear advantage for environmentally conscious consumers and professionals who want to optimize storage space.\u003c\/p\u003e\n\n\u003cp\u003eFor tough situations — heavy insect contamination in summer, road salt residue in winter — the concentration can be temporarily increased to 1:50 or 1:30. This flexibility, which a ready-to-use product does not offer, makes it possible to cover different cleaning intensities with a single concentrate and adapt the product seasonally.\u003c\/p\u003e\n\n\u003cp\u003eThe surfactant formulation of the Windscreen Cleaner 1:100 is designed for biodegradability and material compatibility. The ingredients are chosen so that rubber seals on windshield wipers, plastic wiper frames, and paint edges of the windshield frame are not attacked. This is not a matter of course with highly concentrated formulations — inexpensive private-label concentrates sometimes use aggressive solvents that can make rubber brittle. SONAX systematically tests material compatibility as part of product development and thus provides a reliable basis for continuous use in commercial vehicle fleets.\u003c\/p\u003e\n\n\u003ch3\u003eCorrect Application of Windscreen Cleaner 1:100 — Dosing, Filling, and Seasonal Use\u003c\/h3\u003e\n\n\u003cp\u003eDosing the 1:100 concentrate is easy to calculate: For a 3-liter windshield washer tank, 30 ml of concentrate is needed; for a 5-liter tank, it's 50 ml. A simple kitchen syringe or a graduated dosing bottle helps to measure the exact amount without weighing. In practice, however, the concentration can also be slightly increased without causing damage — the Windscreen Cleaner 1:100 is generously formulated and tolerates moderate overdosing.\u003c\/p\u003e\n\n\u003cp\u003eFor summer use, where insects and road grime dominate, the standard dilution of 1:100 is recommended. For journeys to insect-rich areas or dusty country roads, the concentration can be increased to 1:70 to 1:50. The \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\"\u003eSONAX XTREME Windscreen Cleaner \"Summer\"\u003c\/a\u003e is the ready-to-use alternative for those who do not want to dose — but the concentrate offers a much better price-performance ratio in comparison.\u003c\/p\u003e\n\n\u003cp\u003eAfter filling the tank, the effect of the fresh wiper fluid can be checked immediately: A brief activation of the windshield wiper on a dry windshield shows whether the concentrate is evenly distributed and works streak-free. If there is too little concentrate, streaks can occur; with the right amount, there is a uniformly clear picture. This simple effectiveness check makes setting the correct dosage uncomplicated.\u003c\/p\u003e\n\n\u003cp\u003eOn the front windshield, which is exposed to direct sunlight, streak-free performance is particularly relevant. Wiper streaks reflect sunlight and can significantly restrict the driver's field of vision — especially in oncoming light situations during morning or evening drives. A windshield washer fluid that leaves no residues after drying is therefore not just a comfort feature, but a direct contribution to driving safety.\u003c\/p\u003e\n\n\u003cp\u003eAnyone who uses the concentrate in a vehicle pool or a commercial fleet benefits from the fact that a standardized dosage per vehicle type can be defined once and then applied repeatedly. A small sign in the storage room with tank volume and required concentrate quantity per vehicle model is sufficient — employees do not need chemical knowledge but simply follow the quantity key. This significantly reduces training effort compared to more complex care systems.\u003c\/p\u003e\n\n\u003ch3\u003eAreas of Application for Windscreen Cleaner 1:100 — All-Season Use and Special Cases\u003c\/h3\u003e\n\n\u003cp\u003eThe Windscreen Cleaner concentrate 1:100 is primarily optimized for the summer season — it is not an antifreeze and is not suitable for temperatures below freezing. In summer, where insects, pollen, exhaust residues, and road dust affect the windshield, the concentrate is the most efficient means for clear vision. For the winter season, a winter screenwash should be used.\u003c\/p\u003e\n\n\u003cp\u003eThe 250ml bottle is ideal for the glove compartment or trunk — an emergency refill supply that takes up hardly any space. Those who are traveling long distances or abroad can simply carry the concentrate and buy water on the go, instead of having to transport heavy wiper fluid canisters. This travel logic is one of the most practical advantages of the super concentrate compared to ready-to-use alternatives.\u003c\/p\u003e\n\n\u003cp\u003eFor detailing businesses and workshops that fill the windshield washer tank of customer vehicles as a service, the 1:100 concentrate is economically optimal: Storing several 250ml bottles is more space-saving than stocking 5-liter canisters, and the concentrate is easier to dose and portion.\u003c\/p\u003e\n\n\u003cp\u003eAnother, often overlooked area of application is use in motorhomes and campervans. Motorhome drivers often travel long distances through different climate zones, where insect density and dust pollution vary greatly. The super concentrate allows one to get by with a single small bottle for the entire travel season — and to adjust the concentration depending on the section of the route. At the same time, the compact format saves considerable space in the limited storage space of a motorhome compared to carrying canisters.\u003c\/p\u003e\n\n\u003ch3\u003eWindscreen Cleaner 1:100 in Comparison — Concentrate vs. Ready-to-Use and Other Products\u003c\/h3\u003e\n\n\u003cp\u003eCompared to the \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\"\u003eready-to-use SONAX XTREME Windscreen Cleaner \"Summer\"\u003c\/a\u003e, the 1:100 concentrate offers clear advantages primarily in terms of price and storage volume. If you buy a 5-liter bottle of ready-to-use wiper fluid, you pay significantly more per liter compared to the concentrate version. The ready-to-use variant, on the other hand, offers its convenience argument: no mixing, no dosing, immediately ready for use.\u003c\/p\u003e\n\n\u003cp\u003eCompared to commercially available inexpensive wiper fluids, the XTREME concentrate distinguishes itself by its formulation-optimized streak-free performance. Inexpensive products often contain insufficient dewatering agent components and leave visible films on the windshield after drying. The SONAX quality standard — also in the concentrate variant — ensures that the cleaning performance and streak-free finish are maintained even after extreme dilution.\u003c\/p\u003e\n\n\u003cp\u003eFor external windshield cleaning — manual cleaning of the windshield with a cloth — the concentrate is also suitable as a mixture with water in a spray bottle.

The 250ml concentrate yields 25 liters at a comparable price — so less than 0.50 euros per liter with a significantly superior cleaning result. This is an argument that convinces even drivers who have not actively looked for a concentrate before.\u003c\/p\u003e\n\n\u003ch3\u003eBuying SONAX XTREME Windscreen Cleaner 1:100 — Who Benefits from the Super Concentrate\u003c\/h3\u003e\n\n\u003cp\u003eThe super concentrate is aimed at anyone who wants to buy and store their wiper fluid economically — private drivers who keep the concentrate in the glove compartment, workshops and detailing businesses that service customer vehicles, and travelers who do not want to transport ready-to-use wiper fluid on trips abroad.\u003c\/p\u003e\n\n\u003cp\u003eIt's worth getting started with the SONAX XTREME windscreen care range: With the Windscreen Cleaner 1:100 as a wiper concentrate, the Window Clear as a glass cleaner for manual exterior cleaning, and the Microfiber Cloth \"Glass\" for residue-free wiping, you have all the tools for clear vision year-round in a compact package. The 250ml bottle of Windscreen Cleaner 1:100 is sufficient for an entire summer season with normal use — a supply that you hardly notice until it's gone.\u003c\/p\u003e\n\n\u003cp\u003eFor those who value a complete overview of the SONAX windshield care system: The concentrate covers regular wiping operations, while glass cleaners and glass sealants take care of manual deep cleaning. This dichotomy — automatic wiper fluid cleaning and manual glass preparation — makes it possible to maintain consistently clear windows with minimal effort, without the need for complex care protocols or expensive specialized services. The super concentrate is the most economical entry into this system.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"250ml","offer_id":49160881045839,"sku":"D1-SNX-02711410","price":9.43,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/Sonax-XTREME-ScheibenReiniger-1-100-5.png?v=1721514202"},{"product_id":"sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig","title":"XTREME Windshield Cleaner \"Summer\" Wiper Fluid (Ready to Use)","description":"\u003ch2\u003eClear Vision Without Mixing — SONAX XTREME Windscreen Cleaner \"Summer\" Ready-to-Use\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat does SONAX's ready-to-use summer screenwash do?

Insect residues on the windscreen quickly spread into a wide smear film in the rain, which is not completely dissolved by the wiper without suitable washing water. This can significantly reduce visibility within a few wipes — especially in the dark, when the glancing light of oncoming drivers intensifies the smear film on the window. High-quality, ready-to-use summer screenwash is not a matter of comfort, but of driving safety: it must function reliably when needed.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e For stubborn insect residues on the window, it is advisable to briefly activate the washing water before driving and let the wiper soak the layer for a few seconds before wiping. The soaking water dissolves the dried insect proteins, allowing the wiper to pick them up in one pass without smearing the window. For manual cleaning of the windscreen at rest areas or petrol stations, the ready-to-use summer screenwash is also very effective as a spray solution with a microfiber cloth — a little screenwash from the tank in a small container, and a \u003ca href=\"\/en\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\"\u003eSONAX PROFILINE Microfiber Cloth \"Glass\"\u003c\/a\u003e for residue-free cleaning.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFormulation and Technology of the Ready-to-Use Summer Screenwash\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME Windscreen Cleaner \"Summer\"\u003c\/strong\u003e is based on a surfactant-water formulation specially developed for the demands of the summer season. In contrast to year-round or anti-freeze screenwashes, which must optimize their formulation for freezing point depression, pure summer screenwash can concentrate all additives on cleaning performance and streak-free results. The result is a formulation that dissolves insect residues, pollen contamination, and greasy exhaust particles more effectively than all-round screenwashes with anti-freeze components.\u003c\/p\u003e\n\n\u003cp\u003eSpecial surfactants are responsible for the streak-free finish, which evenly draw the water off the window surface after the wiping process. These dewatering agents prevent the water film from breaking down into individual drops or puddles that leave circular residues when drying. Instead, the screenwash dries evenly and with low residue — a characteristic that makes a particular difference in strong sunlight, as drying residues appear as dazzling streaks in oncoming light.\u003c\/p\u003e\n\n\u003cp\u003eThe formulation is material-compatible with wiper rubber seals, plastic frames, and painted surfaces around the windscreen. Solvent-containing cheap products attack the rubber lips of the wipers and reduce their lifespan and wiping quality. SONAX systematically checks the material compatibility of its screenwash formulations to ensure continuously reliable function — a quality feature that is often not tested in cheap own-brand products.\u003c\/p\u003e\n\n\u003cp\u003eThe 3-liter bottle is designed for one or two complete tank fillings, depending on the tank size of the respective vehicle. Typical windscreen washer reservoirs hold 2 to 4 liters — the 3-liter bottle therefore completely covers the seasonal change from winter to summer screenwash. Filling in an easy-to-grip jug with a spout makes transfer possible without tools and without spilling. For households with multiple vehicles or for businesses that service multiple customer vehicles, it is worth keeping two bottles in stock to carry out the seasonal change without reordering.\u003c\/p\u003e\n\n\u003ch3\u003eApplication of Summer Screenwash — Filling, Changing, and Seasonal Care\u003c\/h3\u003e\n\n\u003cp\u003eThe application of the ready-to-use summer screenwash is extremely simple: open the tank, drain the old water or empty it completely, pour in the bottle directly. No measuring, no mixing, no source of error. The change from winter to summer screenwash is recommended after the end of the frost period — as soon as nightly temperatures are consistently above 0°C and no more frost protection is needed. In summer, the specially formulated summer water then offers the highest cleaning performance against insects and pollen.\u003c\/p\u003e\n\n\u003cp\u003eAfter filling, the effectiveness can be checked directly: a short wipe impulse on a dry window shows whether the surfactants have wetted evenly. For immediate wiping on a dirty window: let the washing water work briefly before activating the wiper. Especially dried-on insect residues benefit from a short soaking time of 10–30 seconds, which dissolves the protein structure of the insect residues and facilitates the wiping work — fewer streaks, less mechanical stress on the wiper blade.\u003c\/p\u003e\n\n\u003cp\u003eIf the screenwash runs out before summer ends, the same product or at least a compatible summer water formulation should be used when refilling. The mixing of different screenwashes is uncritical if both are solvent-free and designed for the same season. It becomes critical if you mix winter anti-freeze water with a pure summer product — the anti-freeze effect is then diluted, and the risk of frozen lines in the next winter increases. Therefore, completely emptying the tank during the seasonal change is the cleanest method.\u003c\/p\u003e\n\n\u003cp\u003eFor vehicles that are driven year-round and in changing climate zones, a clear seasonal rule is recommended: switch to an anti-freeze screenwash at the end of October, and back to summer water by early April at the latest. The ready-to-use 3-liter format covers the spring change with one bottle, leaving no residue. In autumn, then a new anti-freeze bottle — a clean, clear cycle with no storage effort.\u003c\/p\u003e\n\n\u003ch3\u003eSummer Screenwash for Insects, Pollen, and Road Grime — Effect in Practice\u003c\/h3\u003e\n\n\u003cp\u003eThe summer season places different demands on windscreen washer fluid than winter. While winter screenwashes primarily combat salt and meltwater residues, the adversaries in summer are organic contaminants: insect residues, pollen, tree sap deposits, and greasy particles from road traffic. These contaminants stick differently from mineral residues and require surfactants with specific emulsifying properties for organic fats and proteins.\u003c\/p\u003e\n\n\u003cp\u003eOn motorways and federal roads, where insect density is particularly high in summer, a significant layer of insect splatters accumulates on the windscreen within a few hundred kilometers. Without sufficient cleaning agent in the washing water, these residues are only smeared by the wiper. The SONAX XTREME Summer water formulation is designed so that the surfactants actively penetrate the insect matter and emulsify it — the wiper can then remove it completely in one pass, without leaving the characteristic smear film.\u003c\/p\u003e\n\n\u003cp\u003ePollen contamination is another seasonal problem that affects motorists in spring and early summer. Pollen are microscopic particles that embed themselves in the window and become a sticky coating when wet. The washing water must dissolve these particles and remove them from the window surface before the wiper mechanically spreads them. High-quality summer screenwashes such as the XTREME summer product contain a sufficient amount of surfactant to completely dissolve pollen residues and create clear visibility.\u003c\/p\u003e\n\n\u003ch3\u003eSONAX Windscreen Cleaner \"Summer\" in Comparison — Ready-to-Use vs. Concentrate\u003c\/h3\u003e\n\n\u003cp\u003eAnyone who frequently refills their windscreen washer tank and values maximum flexibility should compare the ready-to-use product with the \u003ca href=\"\/en\/products\/sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat\"\u003eSONAX XTREME Windscreen Cleaner 1:100\u003c\/a\u003e.

For those who maintain multiple vehicles, regularly consume large quantities, or require flexible dosing for varying degrees of contamination, the concentrate is economically superior.\u003c\/p\u003e\n\n\u003cp\u003eThe ready-to-use summer product, on the other hand, always wins in practice when simplicity counts: no measuring, no mixing, no source of error. For drivers who rarely refill the screenwash themselves, for workshops without a dedicated dosing station, or for people who want to carry the screenwash as a take-along item in the boot, the 3-liter bottle is the more convenient solution.
