Mineral deposits like limescale, cement, rust and water spots are chemically bonded and need an acid to break them apart. The \u003cstrong\u003eSONAX PROFILINE MultiClean Acid\u003c\/strong\u003e is the highly concentrated acidic heavy-duty cleaner in the PROFILINE system: built to cut through lime- and mineral-based soiling on wheels, vehicle surfaces, underbodies and hard industrial surfaces. As a 5-litre concentrate with flexible dilution, it's the cost-effective tool for regular pro use in detailing businesses and vehicle wash bays.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHighly concentrated acidic heavy-duty cleaner for mineral soiling.\u003c\/strong\u003e Limescale, rust, cement haze and water spots are alkaline or metallic compounds — an acidic formula reacts with these deposits and turns them into water-soluble ions that rinse straight off.

Depending on the dilution, one litre of concentrate makes several litres of ready-to-use cleaning solution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Always run the acidic cleaner diluted when the surface allows it — save neat use for really stubborn soiling on acid-resistant surfaces only. On painted surfaces, keep the dwell time short and rinse off with plenty of water — acidic cleaners attack clear coat and delicate surfaces if you let them sit too long. Protective gear (gloves, safety glasses) is a must when handling acidic concentrates. As the systemic counterpart we'd point you to the \u003ca href=\"\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e for grease- and dirt-based soiling — together the two heavy-duty cleaners cover the whole pH spectrum of professional vehicle cleaning.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAcidic chemistry in a heavy-duty cleaner — how the MultiClean Acid dissolves mineral soiling\u003c\/h3\u003e\n\u003cp\u003eThe way the acidic heavy-duty cleaner works comes down to an acid-base reaction: mineral deposits like calcium carbonate (limescale) and iron oxides (rust) are chemically alkaline or metallic. An acidic cleaner donates protons and converts these compounds into their ion form — calcium carbonate becomes calcium ions (Ca²⁺) and carbon dioxide (CO₂), iron oxides become soluble iron ions. That's the exact opposite of the original chemical bond, and it makes the deposits water-soluble and rinsable without any mechanical force.\u003c\/p\u003e\n\u003cp\u003eThe acid strength in the concentrate is set so it's effective enough to fully dissolve typical lime and rust deposits within manageable dwell times — while controlled dilution keeps it safe to use on more delicate surfaces. That makes the MultiClean Acid more versatile than specialist single products formulated for one specific soiling type and one specific surface. Thanks to that versatility and dilutability, the concentrate offers very good value for money in pro use.\u003c\/p\u003e\n\u003cp\u003eAn important chemical point with acidic cleaners is material compatibility. Acid-resistant materials like stainless steel, ceramic, glass and many plastics are fully compatible with acidic cleaners. Aluminium and certain light-alloy metals, on the other hand, are sensitive — acids can attack aluminium and leave it permanently dull or create an oxidative film. Painted surfaces tolerate short dwell times and a thorough rinse, but long dwell times or high concentration can cause clear-coat damage. Sticking to the recommended dwell times and dilutions isn't optional here — it's a core part of safe use.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the MultiClean Acid right — dilution, dwell time and workflow\u003c\/h3\u003e\n\u003cp\u003eUsing the acidic heavy-duty cleaner takes a precise approach and a dilution rate matched to the soiling level and the surface. For light lime marks and regular wheel cleaning, go with 1:10 to 1:20 (1 part concentrate to 10–20 parts water). For medium soiling like cement haze or heavier limescale on tiles and hard surfaces, 1:5 to 1:10. For heavy deposits like long-dried rust or massive limescale, you may need 1:2 to 1:5 or neat use — take extra care here and keep it off delicate materials.\u003c\/p\u003e\n\u003cp\u003eWorkflow: wet the surface first with water to open up the substrate and slow the cleaner running off. Lay the diluted MultiClean Acid on generously — spray it straight onto horizontal surfaces, apply it to vertical ones with a sponge or brush. Dwell time 1–5 minutes depending on the soiling level and dilution rate — a visible foaming or fizzing reaction during dwell is a sign the acid is reacting with the mineral deposits and dissolving them. After the dwell, rinse thoroughly with plenty of water — get every bit of rinse water and acidic residue off, especially on metal surfaces that can corrode from acid residue.\u003c\/p\u003e\n\u003cp\u003eAfter cleaning with the acidic heavy-duty cleaner, it's worth doing a follow-up rinse with a neutral or slightly alkaline solution to fully neutralise any acid residue — especially on wheels and metal surfaces you'll be sealing or protecting afterwards. On freshly cleaned wheels, the \u003ca href=\"\/products\/sonax-profiline-ceramiccoating-cc-rim-felgenversiegelung\"\u003eSONAX PROFILINE CeramicCoating \"CC\" Rim\u003c\/a\u003e makes a lasting layer of protection that seriously slows down future lime and brake-dust build-up and makes the next clean easier.\u003c\/p\u003e\n\n\u003ch3\u003eWhere to use it — typical soiling and surfaces for the acidic heavy-duty cleaner\u003c\/h3\u003e\n\u003cp\u003eThe acidic pro cleaner covers a broad range of jobs where mineral or acid-soluble soiling is the main issue. Wheel cleaning is one of the most common: brake dust has no direct affinity for acidic cleaners, but limescale from wash water and mineral films on wheel surfaces come off nicely with the acidic heavy-duty cleaner. On steel and stainless wheels it's no problem — on aluminium wheels, which are more acid-sensitive, bump up the dilution and shorten the dwell time.\u003c\/p\u003e\n\u003cp\u003eCement haze on vehicles and glass is a common headache on cars used near building sites or roadworks. The hard white film of cement dust that settles on paint and glass is alkaline and comes off nicely with the acidic heavy-duty cleaner — on glass (e.g. the windscreen) it's no problem with plenty of rinse water and leaves a clear, clean pane. Mineral water spots and lime rings from well water or hard wash water are another classic job — here the MultiClean Acid is the more heavily concentrated pro tool next to the \u003ca href=\"\/products\/sonax-profiline-waterspot-remover-wasserfleckenentferner-kalkentferner\"\u003eSONAX PROFILINE Waterspot Remover\u003c\/a\u003e, which is built for single-detail care.\u003c\/p\u003e\n\u003cp\u003eFor underbody cleaning, the acidic heavy-duty cleaner works well against lime and mineral deposits that settle in the underbody — though here it makes sense to pair it with an alkaline pre-cleaner for grease- and oil-based soiling before you bring in the acid for the mineral bits. Shop floors, lifts and sanitary fixtures in detailing businesses where lime and mineral films build up can also be cleaned effectively with the diluted cleaner — a cost-effective double use for the large 5-litre container.\u003c\/p\u003e\n\n\u003ch3\u003eAcidic vs. alkaline heavy-duty cleaner — the right pick for every soiling type\u003c\/h3\u003e\n\u003cp\u003eThe SONAX PROFILINE MultiClean system is made up of two complementary heavy-duty cleaners that together cover the whole spectrum of professional vehicle and surface cleaning. The \u003ca href=\"\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/a\u003e is the alkaline pre-cleaner for grease-, oil- and dirt-based soiling — road film, bugs, tar, tyre rubber and organic residue come off nicely with the alkaline formula. The MultiClean Acid, on the other hand, is built for the complementary job: mineral, limey and rust-based deposits that don't react to alkaline cleaners.\u003c\/p\u003e\n\u003cp\u003eRule of thumb: alkaline cleaner first (road film, grease, organic dirt), acidic cleaner in the second pass (lime, rust, mineral films). Day-to-day, a lot of vehicle soiling is a mix — a grimy wheel carries brake dust (metallic\/oxide) as well as road film (organic) and lime films (mineral). You get the best clean by running both cleaners in sequence: Alkaline for the first coarse dirt, Acid for the leftover mineral residue.\u003c\/p\u003e\n\u003cp\u003eAgainst specialist single products like wheel cleaners or descalers, the MultiClean concentrates give you the economic edge of flexibility: one product, adjustable by dilution, for many cleaning intensities and surfaces. For detailing businesses with a mix of customer vehicles and shifting soiling profiles, the systematic MultiClean duo is more cost-effective than a pile of specific single products — and it seriously cuts down on storage hassle too.\u003c\/p\u003e\n\n\u003ch3\u003eBuying the SONAX PROFILINE MultiClean Acid — container size and use calculation\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eSONAX PROFILINE MultiClean Acid\u003c\/strong\u003e comes only in the 5-litre container, which puts it firmly in pro territory: the container size and concentrate format are built for continuous professional use, not the occasional private job. At a 1:10 dilution, 5 litres of concentrate make 50 litres of ready-to-use cleaner — enough for many hundreds of wheel cleans or dozens of full vehicle preps with lime removal. Even at 1:5 dilutions for heavier soiling, the container lasts for a great many cleaning jobs.\u003c\/p\u003e\n\u003cp\u003eFor professional detailing businesses cleaning several vehicles a day and running into mineral soiling regularly, the 5-litre concentrate is the most cost-effective buy. The price per litre of ready-to-use cleaner sits well below the market price for pre-diluted cleaners in consumer containers, depending on the dilution. The investment in the concentrate typically pays for itself within a few weeks of regular use against buying single ready-mixed cleaners.\u003c\/p\u003e\n\u003cp\u003eAs a systematic addition we'd point you to pairing it with the SONAX PROFILINE MultiClean Alkaline — together the two products form the complete cleaning system for every soiling type you run into in professional vehicle prep. Detailing businesses that use the MultiClean duo as a fixed cleaning system get a standardised approach that adapts to every vehicle type and soiling profile and delivers repeatable, solid results.\u003c\/p\u003e\n\u003cp\u003eImportant for businesses using the concentrate regularly: store the product cool and dry, keep it out of direct sunlight and away from frost. Close the container well after use to stop concentration changes from evaporation. In pro use it's worth prepping daily amounts in separate containers — that way you always work with freshly diluted cleaner, which keeps cleaning performance consistent. With these simple handling rules, the 5-litre concentrate is a lastingly cost-effective and effective part of the professional cleaning line-up.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"5 liters","offer_id":53622546366799,"sku":"D1-SNX-6325000","price":50.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-profiline-multiclean-acid-kraftreiniger-sauer_5-liter.png?v=1731053714"}],"url":"https:\/\/detailing1.eu\/collections\/saure-vorreiniger.oembed","provider":"Detailing1","version":"1.0","type":"link"}
