The highly concentrated product is diluted with water at a ratio of 1:100 — a 250ml bottle yields up to 25 liters of ready-to-use windshield washer fluid that removes insects, road grime, and films streak-free.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp\u003eYou hardly consciously buy windshield wiper fluid — until the tank is empty, and you either have to rely on something on the road or reach for expensive 5-liter canisters at the hardware store. 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. For workshops and detailing businesses that refill wiper fluid for customer vehicles, the 250ml bottle allows for compact storage and precise dosing without transferring large quantities.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStreak-Free Visibility Cleaning Without Residues.\u003c\/strong\u003e The concentrate's formulation is designed for complete residue breakdown after drying — no wax film, no surfactant streaks on the windshield after wiping. This property is crucial for driving safety, as film residues, especially in oncoming light, significantly impair the field of vision.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEffective Against Insects, Road Grime, and Road Salt Residues.\u003c\/strong\u003e The active cleaning surfactants in the concentrate emulsify insect residues, grease residues from exhaust fumes, and road grime that accumulate on the windshield. The highly concentrated formulation fully develops this cleaning effect even with extreme dilution, as the active ingredients are dosed accordingly high.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eClear vision on the road is not a comfort feature, but a safety requirement. 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. A little concentrate dissolved in water and applied to a \u003ca href=\"\/en\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\"\u003eSONAX PROFILINE Microfiber Cloth \"Glass\"\u003c\/a\u003e effectively removes windshield coatings.

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. The concentrate offers a dilution ratio of 1:100 — a 250 ml bottle yields 25 liters of ready-to-use screenwash and is therefore significantly cheaper per liter. 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. Both products deliver the same SONAX cleaning quality — the difference lies exclusively in the filling effort and cost-effectiveness.\u003c\/p\u003e\n\n\u003cp\u003eFor manual glass cleaning — cleaning the windscreen from the inside or deep cleaning dried-on deposits — the ready-to-use screenwash is suitable as a spray solution on a microfiber cloth.

The \u003cstrong\u003eSONAX XTREME Ceramic ScheibenKlar 2 in 1\u003c\/strong\u003e tackles two tasks in one step: it cleans vehicle windows, mirrors, and headlights streak-free, while simultaneously applying a hydrophobic ceramic protective layer that causes raindrops to bead up.

Then, with a second, dry SONAX microfiber cloth, buff the product until the window shows an even, streak-free shine. This two-step process separates the cleaning phase from the sealing phase and ensures a more even distribution of the sealing component on a truly clean surface.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e2-in-1 Glass Cleaning and Sealing — How ScheibenKlar Works in One Step\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME Ceramic ScheibenKlar 2 in 1\u003c\/strong\u003e combines two active ingredient groups in one formulation. The first component is an isopropanol-based glass cleaner that chemically dissolves grease films, oily dirt, and residues from insects, bird droppings, and road grime, which are then picked up by the cloth. Isopropanol is a proven glass cleaner that leaves no streaks and evaporates quickly on glass — the result is instant, clear shine without re-wiping.\u003c\/p\u003e\n\n\u003cp\u003eThe second component is the sealing substance, which builds the hydrophobic protective layer. It works synergistically with the cleaning component: when buffed with a dry microfiber cloth, the sealing substance is evenly worked into the glass surface. Glass is macroscopically smooth, but under a microscope, it has a porous, slightly roughened surface. The sealing molecules fill these micropores and create an even, hydrophobic layer on which water no longer adheres in flat layers but contracts into beads and runs off due to air pressure while driving.\u003c\/p\u003e\n\n\u003cp\u003eThe durability of the seal depends on several factors: frequency of window washing, intensity of weather, and quality of wiper blades. With daily use of windshield wipers and intense rain periods, the seal may diminish after four weeks. In dry periods with little wiper use, it often lasts the full six weeks or longer. Refreshing is very simple: apply ScheibenKlar again, buff — the protective layer is immediately restored.\u003c\/p\u003e\n\n\u003cp\u003eAn important aspect of the formula is its compatibility with tinted windows. Many older glass cleaners with aggressive solvents can attack the tint, especially on windows with internal tinting (color films instead of laminated glass). The ScheibenKlar formulation is explicitly approved for tinted windows, making it a safe all-rounder for all vehicle windows.\u003c\/p\u003e\n\n\u003cp\u003eThe formulation contains no silicones, which is a decisive advantage for a glass cleaner with a sealing component. Silicone-containing products on windows can lead to long-term deposits that negatively affect the beading behavior of the wiper blades and are difficult to remove completely during the next car wash. The silicone and hard wax-free sealing component of ScheibenKlar permanently binds to the glass without permanently altering the window surface — it merely protects it. This also makes the product suitable for regular users who do not want to risk deposits.\u003c\/p\u003e\n\n\u003ch3\u003eApplying ScheibenKlar 2 in 1 Correctly — Step-by-Step for Streak-Free Windows\u003c\/h3\u003e\n\n\u003cp\u003eShake the bottle briefly before use. Spray the product on the exterior window — not on hot glass in direct sunlight, as the product will dry too quickly and leave residues. Preferably work in the shade or during cooler morning hours.\u003c\/p\u003e\n\n\u003cp\u003eTake a lint-free SONAX microfiber cloth for windows and interiors and wipe the dirt from the window with the damp product. The cloth picks up grease film, insect residue, and dust particles. Then take a second, dry microfiber cloth and buff the product in a circular motion into the window surface until an even, streak-free shine appears. Immediately wipe off any residues that land on the vehicle's paint with a dry cloth — the product is not intended for paint and can leave deposits if left on for too long.\u003c\/p\u003e\n\n\u003cp\u003eDo not use ScheibenKlar 2 in 1 inside the vehicle. The hydrophobic effect on interior window surfaces can cause the window to fog up more quickly, as moisture is no longer evenly distributed over the surface but beads up. For the interior window, there is the regular XTREME ScheibenKlar without a sealing component.\u003c\/p\u003e\n\n\u003cp\u003eCleaning the side mirrors follows the same principle: spray product, clean with a damp cloth, buff with a dry cloth. On polycarbonate headlights, light pressure is recommended when buffing — the material is more sensitive than glass and reacts to too much friction with micro-damage.\u003c\/p\u003e\n\n\u003cp\u003eFor heavily soiled windows — for example, after a long period of standing, after a tunnel drive, or after an intense insect season — it is recommended to perform the first cleaning round with a dedicated interior cleaner or a pre-wash before applying ScheibenKlar. Coarse dirt or insect residues that are stuck by a layer of road film first need mechanical dissolution so that ScheibenKlar can develop its sealing performance on a truly clean surface. Pre-washing only takes an extra minute — but the quality of the final seal is significantly better.\u003c\/p\u003e\n\n\u003ch3\u003eClear Visibility in Rain and Snow — What the Seal Achieves in Everyday Use\u003c\/h3\u003e\n\n\u003cp\u003eThe biggest everyday effect of ScheibenKlar 2 in 1 is evident in rain. On an unsealed window, rainwater spreads in a thin layer, which obscures visibility through light refraction and leads to intense glare from oncoming traffic. On a sealed window, rainwater contracts into small beads that run off independently due to the wind at higher speeds — from about 60–80 km\/h. The field of vision remains clearer, and the windshield wipers need to be used less frequently.\u003c\/p\u003e\n\n\u003cp\u003eAt lower speeds and when stationary, the seal also offers an advantage: the layer reduces the adhesion of insect residues, bird droppings, and road grime. These substances stick less strongly to the hydrophobic surface and are easier to remove during the next cleaning. This is particularly relevant in the summer season when insects adhere intensely to the windshield and are difficult to remove.\u003c\/p\u003e\n\n\u003cp\u003eIn winter, the seal reduces ice adhesion to the window. Ice adheres less intensely to a hydrophobic surface, is thinner, and is easier to remove with an ice scraper. ScheibenKlar 2 in 1 is not a complete de-icing product — but it makes scraping significantly less tedious than on an unsealed window.\u003c\/p\u003e\n\n\u003cp\u003eEven in fog and morning frost, the seal shows its strength: on sealed windows, frost settles less evenly. Instead of a uniform, firmly adhering layer of frost, often only thin crystal patterns form, which can be removed with a squeegee or ice scraper in a few strokes. Anyone who regularly has to scrape their vehicle early in the morning will clearly feel the difference after the first winter season with ScheibenKlar — especially compared to vehicles whose windows have no protective seal.\u003c\/p\u003e\n\n\u003cp\u003eFor wiper blades, the seal has a positive side effect: clean, well-repelling windows reduce the friction of the wiper blades on the glass. Wiper blades on unsealed windows with a grease film push dirt back and forth instead of removing it — this accelerates the wear of the rubber. On a sealed window, the blades glide more smoothly, clean better, and last longer.\u003c\/p\u003e\n\n\u003cp\u003eIn practice, this means: wiper blades that squeak and wipe streaky after just one season on an unsealed window often run trouble-free for two or three seasons on a window regularly treated with ScheibenKlar. The cost savings on wiper blades are an indirect but measurable benefit of regular window sealing — which quickly puts the product's purchase into perspective.\u003c\/p\u003e\n\n\u003ch3\u003eGlass Cleaners Compared — ScheibenKlar 2-in-1, ScheibenKlar Classic, and PROFILINE GlassPolish\u003c\/h3\u003e\n\n\u003cp\u003eThe SONAX range includes several products for glass cleaning and care. The \u003ca href=\"\/en\/sonax-xtreme-scheibenklar-glasreiniger\"\u003eXTREME ScheibenKlar\u003c\/a\u003e (without 2-in-1) is the classic glass cleaner without a sealing component. It is faster to use because no second buffing step is necessary, but it does not provide a permanent beading effect. For interior windows, where sealing would be counterproductive, it is the right choice. For exterior windows, where the sealing effect is desired, the 2-in-1 is the superior option.\u003c\/p\u003e\n\n\u003cp\u003eFor heavily scratched windows or burnt-in contaminations that a normal glass cleaner cannot remove, there is the \u003ca href=\"\/en\/sonax-profiline-glasspolish-glaspolitur\"\u003ePROFILINE GlassPolish\u003c\/a\u003e — a glass polish with cerium oxide that removes the finest scratches from glass surfaces with a polishing machine or manually. This is a more intensive preparation step that can be used before sealing with ScheibenKlar 2 in 1 to create an immaculate starting condition.\u003c\/p\u003e\n\n\u003cp\u003eFor maximum, long-term window sealing, there is the \u003ca href=\"\/en\/sonax-profiline-ceramiccoating-cc-glass-scheibenversiegelung\"\u003ePROFILINE CeramicCoating CC Glass\u003c\/a\u003e — a professional ceramic seal for windows with a durability of up to 12 months. It is more complex in preparation and application but offers significantly longer durability. ScheibenKlar 2 in 1 is the everyday product for regular care; CC Glass is for intensive basic treatment or for vehicles where minimal maintenance effort is desired for months.\u003c\/p\u003e\n\n\u003cp\u003eA frequently underestimated aspect in comparing the three products is the entry barrier. The PROFILINE CC Glass requires a complete glass preparation — polishing, cleaning, isopropanol degreasing — before the ceramic seal can be applied. Errors in preparation lead to uneven adhesion or stains that can hardly be corrected. ScheibenKlar 2 in 1, on the other hand, is more forgiving: if the window was not perfectly prepared, the seal may lose some durability in that area — but no permanent damage occurs. For private users who want clear windows without a learning curve, ScheibenKlar 2 in 1 is the right entry point into the topic of window sealing.\u003c\/p\u003e\n\n\u003ch3\u003eBuying Glass Cleaner — Who Benefits from SONAX XTREME Ceramic ScheibenKlar 2 in 1\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME Ceramic ScheibenKlar 2 in 1\u003c\/strong\u003e is aimed at vehicle owners who want to clean their windows regularly and at the same time create a lasting beading effect for better visibility and easier cleaning. The 2-in-1 concept makes it particularly attractive for anyone who wants to keep their care efforts low — one product for cleaning and protection instead of two separate steps.\u003c\/p\u003e\n\n\u003cp\u003eScheibenKlar 2 in 1 is particularly recommended for vehicle owners who frequently drive in the rain or who want to improve safety on wet roads. The better visibility provided by beading windows is a noticeable advantage, especially during night drives in the rain, which increases reaction safety. Regular application every four to six weeks is sufficient to maintain the effect permanently.\u003c\/p\u003e\n\n\u003cp\u003eEven for vehicle owners who rarely wash their car or have little time for maintenance, ScheibenKlar 2 in 1 is a smart solution. Unlike dedicated window seals, which must be planned as a separate step after a complete cleaning, ScheibenKlar 2 in 1 can be conveniently integrated into the normal cleaning routine. Wiping the windows with ScheibenKlar once a month during vehicle cleaning is enough to consistently have clear, hydrophobic windows. No retooling, no second bottle, no extra time. This is the real promise of the 2-in-1 concept: maximum everyday suitability with minimal effort.\u003c\/p\u003e\n\n\u003cp\u003eFor vehicles with polycarbonate headlights that are clouded by UV radiation, ScheibenKlar 2 in 1 offers a simple maintenance solution for the surface — it cleans and protects the headlights without elaborate polishing. Used as a supplementary care product after a complete vehicle wash, it is quick to apply and delivers reliable results that improve both vehicle appearance and driving safety.\u003c\/p\u003e\n\n\u003cp\u003eOnce you have experienced the difference between unsealed and sealed windows during a rainy drive, you will make ScheibenKlar 2 in 1 a permanent part of your care routine — not because it is a luxury product, but because it delivers real, measurable added value in everyday life. Clear windows are not a luxury. They are the basis of safe driving in all weather conditions. The effort is minimal, the result immediately visible — and with 750 ml of content, one bottle lasts for many months of regular application on all glass surfaces of the vehicle.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"750ml","offer_id":57341581918543,"sku":"D1-SNX-01744000","price":9.23,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-xtreme-ceramic-scheibenklar-2-in-1-glasreiniger-versiegelung.png?v=1774733308"}],"url":"https:\/\/detailing1.pl\/en\/collections\/sonax-scheibenpflege.oembed","provider":"Detailing1","version":"1.0","type":"link"}
