The basis is a nozzle that can be adjusted to work from a finer spray pattern to a more generous application – and SOLO explicitly emphasizes a new\/adjustable universal nozzle that provides a more balanced spray pattern and can be adjusted more precisely for applications.\u003c\/p\u003e\n\u003cp\u003eIn everyday detailing, this \"adjustability\" is more than comfort: for interiors, you often want controlled, fine wetting (e.g., on a microfiber cloth or brush) so you don't flood every crevice. For pre-treatment or large-area cleaning, you want even, quick wetting without the product immediately running off in thick drops. You only get this range if the spray pattern and pressure remain stable – and that's where a pump sprayer proves its worth as a process tool.\u003c\/p\u003e\n\u003ch3\u003eCorrectly Using FKM EPDM A B Labeling and pH 1-7 7-14\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\/B\u003c\/strong\u003e is not a cosmetic model variant at SOLO, but a clear chemical signal. SOLO explains the assignment so that devices with \"B\" are intended for bases\/alcohols in the pH range 7–14, while \"A\" covers acidic applications; in addition, the sealing materials (EPDM vs. FKM) are used accordingly. This is crucial in detailing because we rarely have \"just one cleaner\": APC, pre-cleaners, special surface cleaners – all can differ significantly chemically.\u003c\/p\u003e\n\u003cp\u003eConsequence in practice: If you use typical alkaline cleaners, pre-treatments, or many alcohol-based applications, you take the B variant (EPDM). For acidic media or special applications in the low pH range, the A variant (FKM) is the right one. SOLO describes, for example, the 305 B with EPDM seals and a pH range of 7–14, and the 305 A with FKM seals and a pH range of 1–7 – this is exactly the logic you want to get \"right\" immediately when buying.\u003c\/p\u003e\n\u003cp\u003eAnd yes: Even with pump sprayers, the unspectacular pro move applies – rinse after use.

In detailing, it's often not just the product that matters, but how you apply it: too coarse = unnecessary consumption, too fine = dries out, wrong seal = trouble. This is exactly where the CLEANLine series excels: 303 A and 303 B are technically designed the same way, but chemically \"sealed\" differently – so you can use acidic and alkaline cleaners in the appropriate system.

If you work with acidic special cleaners in detailing (classically: lime\/mineral-based deposits, water spots and rust on suitable surfaces, depending on the product), then the A variant is the logical choice – not because \"A is better\", but because the seal matches the medium. Conversely, the \u003cstrong\u003eEPDM seal (303 B)\u003c\/strong\u003e is designed for alkaline cleaners in the pH 7–14 range; SOLO describes EPDM as a sealing material for basic\/alkaline applications and also mentions its suitability for disinfectant solutions. In practice, this means: For typical all-purpose cleaners (APC) and many degreaser\/pre-wash scenarios, you'll often be \"in the green\" with 303 B, while 303 A is your safe bet when you deliberately work with acidic products. Our tip from detailing: If you regularly spray both alkaline and acidic products, really get both variants – this is not a gimmick, but good chemical hygiene. And if you love your storage space: The CLEANLine even has a card\/label system in the spray head, including colored identification cards – great for distinguishing contents and application areas (and yes: this very effectively prevents the \"Oops, wrong cleaner\" moment).\u003c\/p\u003e\n\u003ch3\u003eCar pre-wash and car detailing with pump sprayer Controlled application of cleaning chemicals\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCar pre-wash\u003c\/strong\u003e thrives on chemicals adhering evenly and being able to work – not on you sending half of it into the air as mist. This is exactly what the 1.25-liter form factor is strong for: handy, quick to fill, and large enough to treat a car \"in one go\" without constantly refilling (filling volume 1.25 L). The adjustable hollow cone nozzle allows you to trim the spray pattern so that you get more area or more punch depending on panel size and contamination – and without changing the character of the product. For us in practice, this is the sweet spot for: pre-cleaners\/pre-sprays on lower areas, APC on door sills\/door jambs (with the appropriate pH variant), and targeted wetting of problem areas.\u003c\/p\u003e\n\u003ch3\u003e3 bar spray pressure Hollow cone nozzle safety valve and continuous spraying for a clean spray pattern\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar spray pressure\u003c\/strong\u003e is not just a pub talk figure for a hand pump sprayer, but the point at which the spray pattern and working rhythm become stable: pump, spray, continue working – without being \"empty\" again after three trigger pulls. SOLO specifies 3 bar for both 303 models and combines this with a safety valve that can release pressure for emptying\/refilling and automatically relieves overpressure. In addition, there is the encapsulated pump unit, which shields pump elements from the cleaning liquid to be applied – a detail that in everyday life simply means: less contact of the technology with aggressive chemicals and thus a more robust, consistent function over time. And because we love it in detailing when things \"just work\": The locking slide for continuous spraying is gold when you want to wet larger areas without sending your finger to the gym. If you need more \"foam carpet\" instead of a spray film, check out a foam sprayer\/foamer from us as a supplement – the pump sprayer then remains your tool for pre-sprays, targeted wetting, and working \"with feeling\".\u003c\/p\u003e","brand":"solo","offers":[{"title":"1.25 liters \/ Acid (pH 1-7) 303 A","offer_id":56938331111759,"sku":"D1-SOL-30301","price":19.98,"currency_code":"EUR","in_stock":true},{"title":"1.25 liters \/ Alkaline (pH 7-14) 303 B","offer_id":56938331078991,"sku":"D1-SOL-30302","price":19.98,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-303-a-pumpsprueher-1-25-liter.png?v=1769854142"},{"product_id":"solo-cleanline-304-a-b-pumpsprueher-2-liter","title":"CLEANLine (304 A \/ B) Spray Bottle 2 Liters","description":"\u003ch2\u003ePrecise Spraying Instead of Guessing: solo CLEANLine (304 A \/ B) — 2-Liter Pump Sprayer for Clean, Controlled Chemical Work\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eWhich solo CLEANLine (304 A \/ B) — 2-liter pump sprayer is right for your cleaner? 304 A covers acidic to neutral media (pH 1–7) with FKM, 304 B neutral to alkaline media (pH 7–14) with EPDM – both up to 3 bar.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eThe solo CLEANLine (304 A \/ B) — 2-liter pump sprayer\u003c\/strong\u003e is to detailing what a clean torque wrench is to a workshop: control.

SOLO deliberately separates this in the CLEANLine according to pH window: If it's about applying concentrated or diluted acids in the pH 1–7 range, devices with FKM seals are the right choice; if it's alkaline (pH 7–14), EPDM is used as the sealing material. \u003c\/p\u003e\n\u003cp\u003eFor you as a detailer, this can be translated in a wonderfully pragmatic way: If you're doing typical acidic applications (e.g., acid-based cleaners that address mineral residues and deposits), it belongs in the A-world – and that's exactly what 304 A is for. If your daily routine tends to be alkaline (classically: many pre-cleaners\/APCs\/degreaser setups designed to dissolve organic dirt), 304 B is the clean decision. The point isn't \"acid good \/ alkali bad\" – the point is material compatibility and consistency: Seals must seal and move while in contact with the medium. If you combine them incorrectly here, you rarely notice it immediately with the first spray, but later: pressure drops faster, operation becomes rougher, small parts age unnecessarily.\u003c\/p\u003e\n\u003cp\u003eNice-to-know (because it really happens in practice): SOLO also mentions suitability for oil- or partially chlorinated hydrocarbon-containing agents for FKM. This is not a free pass for experimentation, but it explains why many professionals prefer to stay in the FKM world for \"chemically demanding\" media – as long as the pH application fits. And because we don't do detailing in a lab, but between the rim, sill, and door jamb: If you use several media in parallel, the A\/B logic is the simplest way to avoid errors. Label content, assign the correct device, done.\u003c\/p\u003e\n\u003ch3\u003eUtilizing 3 bar Pump Pressure, Encapsulated Pump, and Adjustable Universal Nozzle in Detailing\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar pump pressure\u003c\/strong\u003e sounds technical at first – but in reality, it's the difference between \"constantly repumping\" and \"working in a smooth flow.\" SOLO states for the 304s that with the efficient pump, you can effortlessly achieve an operating pressure of up to 3 bar, enabling sufficiently long work intervals. This makes the sprayer so pleasant in everyday car care: You can evenly wet a surface without the spray becoming weak after ten seconds.\u003c\/p\u003e\n\u003cp\u003eThe second professional component is the fully encapsulated pump unit. SOLO explains that the encapsulated pump shields the pump elements from the chemically active cleaning fluid, thus contributing to a long service life. Translated: Less direct \"chemical stress\" in the mechanical core, less risk of the pump feel or tightness deteriorating over time – provided you don't treat the device like a disposable item after use (more on that in a moment).\u003c\/p\u003e\n\u003cp\u003eAnd then there's what you immediately feel with every application: the nozzle and operation. SOLO mentions a new, adjustable universal nozzle for a more balanced spray pattern, and for 304 B, it explicitly includes the adjustable hollow cone nozzle, allowing you to set the spray volume and pattern. Additionally, there are ergonomic controls, a comfortable trigger lever, and a locking slider that lets you switch between continuous spraying and spot spraying while working. This is pure gold in detailing: precise application on emblems, seams, and edges – and the next moment, wide coverage on pre-wash zones, without cramping your hand or breaking up your workflow.\u003c\/p\u003e\n\u003cp\u003eHighly underestimated, but a real quality indicator in everyday use: filling and stability. According to SOLO, the container is made of sturdy, UV-resistant polyethylene, stands on three feet, has a large filling opening, and a fill level marking in the translucent material. This isn't just \"nice,\" it's a time-saver: quicker mixing, less spilling, cleaner storage – and if you work professionally, these are precisely the details that make the session enjoyable in the end.\u003c\/p\u003e\n\u003ch3\u003eCleaning, Releasing Pressure, and Workflow Tips for Long-Lasting Enjoyment of Your Pump Sprayer\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCleaning and releasing pressure\u003c\/strong\u003e is not a boring chore for a pump sprayer, but the part that preserves your spray quality. SOLO describes a safety valve through which excess container pressure can be released for emptying, refilling, or cleaning, and that pressure above 3 bar is automatically released via this valve. For your process, this means: After working, first release pressure in a controlled manner, then open – and not vice versa. This keeps things clean and predictable.\u003c\/p\u003e\n\u003cp\u003eIf you're aiming for consistent results in detailing, establish a simple routine: After use, empty any remaining medium, rinse with clear water, spray water through once (so that the nozzle and lines are also clear), then store dry\/clean. This prevents residues from drying on valves and nozzles and ruining your spray pattern during the next use. And yes: Especially with \"more active\" cleaners, this is doubly worthwhile, as you don't leave the seals constantly exposed to the medium. The original operating instructions show cleaning and maintenance actions, as well as disassembling\/checking nozzle parts – a good reminder that such a tool deserves care if it's to perform like a professional tool.\u003c\/p\u003e\n\u003cp\u003ePractical (and quite cleverly solved): For 304 B, SOLO mentions a card holder integrated into the spray head for labeling the container contents, including writable media cards. For you, this means: No more \"Was that the wheel cleaner... or?\" – you label clearly according to the application area and automatically grab the right one in your workflow.

In detailing, you work with very different formulations depending on the task: wheel cleaners can be more acidic, many pre-cleaners\/all-purpose cleaners are alkaline, and there are also alcohol-based mixtures or degreasers. This is exactly where SOLO consistently separates the variants by application: The 305 A is intended for acidic media in the pH range 1–7 and uses FKM seals; the 305 B is designed for alkaline media in the pH range 7–14 and uses EPDM. This is not a marketing gimmick, but material science: elastomers react differently depending on the chemistry – and the best pump is useless if seals swell, harden, or simply leak. So, if you regularly switch between \"more acidic\" and \"more basic,\" proper assignment is the basis for predictable results and smooth work.\u003c\/p\u003e\n\u003ch3\u003eApplication in Detailing: Pre-wash, Wheels, Engine Bay \u0026 Workshop – How to Really Use 5 Liters Efficiently\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePre-wash and alkaline cleaners\u003c\/strong\u003e are the sweet spot for many – and this is exactly what the 305 B (EPDM, pH 7–14) is made for: You wet large surfaces quickly and evenly, allowing surfactants to work and reducing mechanical contact in the next step because dirt is \"loosened\" beforehand. For acidic applications (depending on product logic, e.g., if you are specifically targeting calcareous residues or certain mineral deposits), the 305 A (FKM, pH 1–7) is suitable – it is important that you always stick to the intended medium instead of playing \"it'll be fine.\" In practice, this means you use the sprayer as a distribution tool, not as a foam sprayer substitute. For real foam dwell time, use a dedicated foam sprayer; the CLEANLine 305 is designed for controlled application of liquids.\u003c\/p\u003e\n\u003ch3\u003eSpray Pattern, 3 Bar Pressure Build-up, and Handling: Why the CLEANLine 305 A\/B Feels So \"Pro\"\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e3 bar working pressure and a flat jet nozzle\u003c\/strong\u003e are the combination that simply works in everyday use: you get a uniform liquid film instead of random droplet landscapes. The maximum spray pressure is 3 bar; the generously sized piston pump builds up pressure with just a few strokes – you'll notice this immediately when working on larger surfaces and not wanting to re-pump every 20 seconds. The 5-liter container is deliberately designed to be robust; the CLEANLine catalog highlights the very high container robustness (including 7 mm wall thickness), carrying strap, stand, and ergonomic controls for the 305 models. For practical use, this means: stable standing during pumping, clean handling when moving it, and less \"fumbling\" during breaks because the lance can be neatly guided. The key data are also clearly trimmed for everyday work: 5 L nominal volume, 50 cm spray lance, and 1.4 m hose, plus an empty weight of around 2.6 kg (depending on model\/equipment) – that's compact enough for the vehicle, but large enough for serious surfaces. And yes: a safety\/overpressure valve for pressure release is included, so you can release the pressure in a controlled manner instead of fighting against the lid.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"solo","offers":[{"title":"2 liters \/ Acid (pH 1-7) 305 A","offer_id":56938499080527,"sku":"D1-SOL-30505","price":67.92,"currency_code":"EUR","in_stock":true},{"title":"2 liters \/ Alkaline (pH 7-14) 305 B","offer_id":56938499047759,"sku":"D1-SOL-30506","price":67.92,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/solo-cleanline-305-b-pumpsprueher-5-liter.png?v=1769856475"}],"url":"https:\/\/detailing1.pl\/en\/collections\/solo-pumpsprueher.oembed","provider":"Detailing1","version":"1.0","type":"link"}
