Professionally remove rust film and iron particles — SONAX PROFILINE Rust Film Remover "Power Cleaner Acid"

What does the SONAX PROFILINE Rust Film Remover "Power Cleaner Acid" do? The acidic iron particle remover chemically dissolves rust film, brake dust deposits, and lime residue on paint, glass, rims, and bodywork — formulated for professional continuous use in large containers.

Rust film is a problem many vehicle owners underestimate: what starts as a small rust-colored spot can, in the long term, develop into real paint corrosion if left untreated. The cause lies in the nature of iron particles from brake dust, rail dirt, and industrial emissions — they not only settle on the paint surface but also penetrate deeper into the paint structure when exposed to moisture and heat, causing rust from within. Anyone who details vehicles daily knows the problem: rust film and iron particles adhere to paint, glass, and bodywork and are difficult to remove with conventional cleaners alone. Standard shampoos are insufficient, and mechanical polishing would be too complex and risky. What is needed is an acidic iron remover that attacks chemically with precision. This is exactly what the SONAX PROFILINE Rust Film Remover "Power Cleaner Acid" is: a professional power cleaner for commercial use that chemically dissolves rust film particles, brake dust deposits, and lime residue — available in containers of 10, 25, and 60 liters for continuous use in car washes, body shops, and vehicle fleets.

Acidic power formula for stubborn rust film and iron particles. The acidic formulation chemically dissolves iron oxides without mechanical intervention on the surface. The cleaner directly attacks iron particles originating from brake dust, rail dirt, and industrial emissions, dissolving them for residue-free rinsing.

Large container sizes for continuous commercial operation. 10, 25, and 60 liters — the container sizes are clearly aimed at professional users. Those who treat dozens of vehicles daily benefit from the economical large-container solution instead of small quantities.

Use on paint, glass, rims, and bodywork. The power cleaner is suitable for all typical vehicle surfaces where rust film settles — not just rims, but also paint surfaces, windows, and exterior bodywork. A wide range of applications for a cleaner in the professional sector.

Practical tip from Detailing1: Always wear protective gloves and safety glasses when using the acidic power cleaner. Do not use the product on hot surfaces and never leave it on for longer than the recommended exposure time — acidic cleaners can attack paint surfaces or sensitive surfaces if the exposure time is exceeded. Always rinse thoroughly with water.

Acidic iron remover — how the chemistry behind the power cleaner works

Rust film is not ordinary dirt. Iron particles — from brake pads, rail contact, and industrial emissions — literally embed themselves in paint, glass, and bodywork. Oxidation creates iron oxides that are trapped in the paint structure and are visible from the outside as small rust-colored spots. Mechanical polishing would at best rub these particles in without removing them. The correct approach is chemical: an acidic iron remover attacks the oxide layer that holds the iron particles on the surface and dissolves the bond. The particles can then be rinsed off with water — the rust film is completely removed. The SONAX PROFILINE Rust Film Remover "Power Cleaner Acid" works with an acidic pH value that is strong enough to effectively dissolve iron oxides, while remaining controllable in the recommended application. Important to know: "Acidic" in this context does not mean uncontrolled aggression. The formula is compatible with paint and glass when used correctly — i.e., at normal operating temperature of the surface, with sufficient water, and within the recommended exposure time. Caution is advised on weathered, dull, or damaged paint: acidic cleaners can exacerbate existing damage. On intact new paint and coated surfaces, the product is suitable for occasional use.

Unlike so-called "color indicator iron removers," which show a color change when reacting with iron particles, this power cleaner does not show a color change — this is not a defect, but a conscious positioning as a concentrated professional cleaner. The focus is on effectiveness and efficiency, not on visual effects. For businesses that need clear processes, this is an advantage: apply, observe exposure time, rinse, done.

For those wondering how acidic power cleaners differ from alkaline cleaners: Alkaline cleaners are optimized for greasy dirt such as oil, soot, and organic dirt. Acidic cleaners, on the other hand, are particularly suitable for mineral and metallic deposits — i.e., lime, rust, iron oxides, and mineral deposits from rainwater. In professional workflows, both are often used: an alkaline pre-cleaner for organic dirt, then an acidic cleaner for iron particles and mineral residues. This two-stage approach is the gold standard in professional vehicle detailing and delivers the cleanest result before sealing or polishing work.

Properly applying rust film remover — instructions for professional use

The correct procedure is particularly important with an acidic power cleaner. First, prepare the vehicle with a basic wash — coarse dirt layers should be removed before the iron remover is applied. Ensure that the surface is not in direct sunlight and is not heated: acidic cleaners react more aggressively on warm surfaces and dry faster, which can lead to uneven action. Apply the power cleaner evenly with a spray bottle, pump sprayer, or foam gun. The recommended exposure time varies depending on the degree of contamination — typically 2–5 minutes for normal rust film. Work on the vehicle section by section so that no part is exposed for too long. After the exposure time, rinse thoroughly with plenty of water. A high-pressure cleaner supports the complete removal of dissolved particles. In case of heavy rust film contamination, a repetition may be necessary. After rinsing, a pH-neutral post-treatment with a shampoo or active foam is recommended to neutralize acid residues. Only after this step should the vehicle be prepared for further care work such as polishing or sealing.

For use in a professional car wash or tunnel: The power cleaner can be integrated into the dosing system. The concentration depends on the system and the desired effectiveness — for this, we recommend consulting the system manufacturer and SONAX for precise dosing recommendations. For manual application, the concentration in the bottle is already ready for use.

A common mistake in practice: The product is applied to a hot vehicle that has just come from a drive. On surfaces above 40°C, the acidic cleaner dries faster than expected, the reaction becomes uncontrollable, and discoloration can occur. Therefore, always park the vehicle in the shade and wait until the surface has cooled to room temperature. This usually takes 15–20 minutes, but prevents potential damage and ensures a uniform cleaning result over the entire vehicle surface.

Areas of application — when and where the power cleaner is needed

The SONAX PROFILINE Rust Film Remover "Power Cleaner Acid" is designed for the following areas of application: Vehicles with heavy rust film contamination due to industrial environments, rail traffic, or highway driving; regular rust film treatment as part of a professional detailing workflow; pre-cleaning before paint correction, vehicle sealing, or coating application; bodywork cleaning in paint shops and body repair shops; fleet maintenance with many vehicles and a high degree of contamination. The product is particularly important as a workflow step before sealing: rust film particles trapped under a sealant continue to rust and can damage the sealant from the inside out in the long term. For anyone who wants to perform professional vehicle detailing with maximum results: paint decontamination — the removal of iron particles, resin contamination, and residues — is an indispensable step before polishing, sealing, or coating. Skipping this step risks trapping dirt particles under the sealant and long-term impairment of the final result. Therefore, anyone who wants to professionally seal or ceramic coat a vehicle should absolutely perform iron removal beforehand. The PROFILINE Rim Cleaner Red Max is a complementary product for intensive rim cleaning in the same workflow — it combines iron removal with a color indicator for visual cleaning control directly on the rim. For rim sealing after cleaning, the PROFILINE CeramicCoating CC Rim line is suitable.

The rust film remover is also suitable for treating vehicles that are located near railway lines, steelworks, or industrial facilities and are thus exposed to increased iron particle fallout. For fleet operators whose vehicles regularly travel on highway routes with a high proportion of rail networks, a regular iron removal routine is a sensible investment in paint preservation.

Another area of application that is often underestimated in professional operations: vehicle acceptance during used car detailing. Vehicles that have been left untreated for months or parked in industrial areas often show significant iron contamination that is barely visible to the naked eye. The clay test — simply running clay over the paint surface — shows the extent: If the clay is covered with small rough spots after a short time, iron particles are deeply embedded in the paint. In these cases, an acidic iron remover is the first measure before clay, polishing machine, or coating is used. A thorough acidic pre-treatment step also significantly reduces clay consumption, as fewer particles need to be removed mechanically. For detailers who treat such vehicles daily, this means direct time and material savings — a clear argument for the regular use of the professional power cleaner in the detailing workflow.

Power cleaner comparison — acidic vs. neutral iron removers

The question "Acidic or neutral iron remover?" is one of the most common in the detailing sector — and the answer, as often is the case, is: It depends on the application. For knowledgeable use, it's worth knowing the differences precisely, rather than blindly choosing one option.

The SONAX portfolio includes several iron remover products that use different active principles. The most important distinction is between acidic power cleaners like this one and pH-neutral iron removers with a color indicator (like FelgenBeast or Iron Removers). pH-neutral iron removers work by chelation: They chemically bind iron particles and remove them from the surface without using a strongly acidic pH value. This makes them gentler on paint surfaces and easier to handle — but for very high iron contamination or large-scale application, also slower and more labor-intensive. Acidic power cleaners like the Rust Film Remover "Power Cleaner Acid" have a faster effect on high iron contamination and are particularly suitable for commercial throughput where many vehicles need to be treated in a short time. The PROFILINE MultiClean "Acid" Power Cleaner is another option for acidic cleaning in the PROFILINE range, with a different focus on multi-surface cleaning. The choice between acidic and neutral iron removers depends on the application scenario: For elaborate individual vehicle detailing and on sensitive paints, a pH-neutral remover is preferable. For professional mass use and heavily contaminated vehicles, the acidic power cleaner is the more efficient choice.

The difference is also evident in the processing time: A pH-neutral indicator remover often requires 5–10 minutes of exposure time to await the color reaction and completely dissolve the iron particles. An acidic cleaner reacts faster — 2–4 minutes are sufficient in most cases. In a business with 20 vehicles a day, these minutes add up to significant time savings over a work week.

Finally, costs also play a role: Per liter, a concentrated acidic power cleaner in large containers is considerably cheaper than individual bottles of pH-neutral indicator products. For commercial use, the cost difference is clearly noticeable with regular application. This makes the power cleaner not only more powerful for its purpose but also economically superior in professional operations.

Purchase recommendation — for whom the PROFILINE Rust Film Remover is the right solution
