Koch-Chemie Reactive Rust Remover Rrr — Iron & Fallout Remover

pH-Neutral Reactive Iron Fallout & Brake Dust Remover with Color Indicator

Koch-Chemie Reactive Rust Remover (Rrr) is a powerful, acid-free, pH-neutral chemical decontaminant engineered to eradicate embedded iron particles, industrial rail dust, and stubborn brake dust from automotive clearcoats, alloy wheels, and glass. The specialized reactive formulation reacts with iron oxide molecules, transforming them into a water-soluble complex visualized by an intense purple bleeding response.

Key Performance Advantages

• pH-Neutral Safety: Gentle on exterior paints, clearcoats, polished alloy rims, and sensitive chrome trims unlike aggressive mineral acids.
• Active Color Indicator: Turns deep violet/purple upon contact with ferrous contamination to visually confirm active chemical dissolution.
• Gel Consistency: Clings to vertical surfaces (doors, wheels, quarter panels) for extended dwell time without running off prematurely.
• Gloss & Slip Boosters: Contains specialized surfactants that gently lubricate surfaces to prevent wash scratching during rinse-off.

Recommended Application Protocol

• Application: Spray undiluted Rrr evenly across clean, cool panels or wheels from a distance of approximately 20 cm.
• Dwell Time: Allow to react for 3–5 minutes until the formulation bleeds intense purple. Do not allow to dry completely.
• Agitation: For heavily neglected wheels or textured trim, agitate gently using a soft wheel brush (Felgenbürste) or microfiber mitt.
• Rinsing: Rinse thoroughly with high-pressure water until all purple chemical runoff is completely eliminated.

Precautions & Pro Tips

• Sunlight & Heat: Never apply on hot surfaces or in direct midday sunlight.
• Sensitive Bare Metals: Test on an inconspicuous area before applying to unlacquered custom anodized wheels.
• Storage: Store upright between +5 °C and +25 °C. Protect from frost.
