KOCHCHEMIE Reactive Rust Remover 500 ml — pH‑Neutral Wheel & Brake Cleaner, Gentle Chelating Formula

This professional-grade 500 ml formulation combines effective metal-targeting detergents with a gentle pH-neutral base so you can remove inorganic contaminants without aggressive acids. Ready-to-use from the bottle, it can also be diluted for spray or foam application. The product is aimed at technicians and car detailing enthusiasts who need targeted removal of rust stains and brake deposits while preserving painted or coated surfaces.

How does this cleaner remove rust and brake dust without harsh acids?

The formula uses specialized chelating and dispersing agents that react with metal particles and loosen burnt-on brake residues while keeping the pH neutral. This reduces the risk of stripping coatings or causing etching on compatible surfaces when used correctly.

• pH-neutral detergents target inorganic pollutants rather than attacking paints
• Chelators and dispersants lift metal particles for easy rinsing
• Safe for painted surfaces and most wheel types when applied per instructions

When should I use the product during a wheel or brake service?

Use it after an initial rinse or pre-wash to focus on metal contamination areas: wheel barrels, caliper faces, leading edges, and around lug areas. It performs best on cooled surfaces and when allowed a brief dwell for reaction before rinsing or agitating.

• Apply to cooled wheels and brake components only, away from direct sunlight
• Allow short dwell time, then agitate or rinse to remove loosened deposits
• Compatible as a step before detailing, sealing or repainting when contaminant-free surface is required

Can I dilute it and use it with a foam cannon or sprayer?

Yes — the product is formulated to be effective both straight from the bottle and when diluted for different application methods. Adjust concentration based on contamination level: stronger for stubborn rust, milder for routine maintenance.

• Ready-to-use for spot treatments and heavy deposits
• Dilutable for larger areas or foam application in sprayers/cannons
• Designed for longer contact time without rapid runoff, improving cleaning efficiency

What precautions should I take to protect finishes and ensure safety?

Although pH-neutral, the cleaner is designed for professional use and requires basic precautions: avoid application on hot surfaces, do not use in direct sunlight, and follow rinse and dilution guidance to prevent residue. Test on an inconspicuous area if unsure about compatibility.

• Do not apply to hot parts or in direct sunlight to avoid streaking or drying
• Rinse thoroughly after use and follow recommended dilution rates
• Use personal protective equipment when handling concentrated product

Who is this for?
