## Overview

KOCHCHEMIE Reactive Rust Remover is a powerful, pH-neutral cleaner designed to safely and effectively remove superficial rust, metal particles, burnt-in brake dust, and other non-organic pollutants from metal surfaces. Its unique formula extends contact time for deep stain dissolution, changes color to indicate active cleaning, and rinses off easily without damaging painted or sensitive parts. Trusted by professionals since 1968, this 5-liter solution is perfect for automotive and industrial use, delivering expert-level results with every application.

## Description

This powerful, pH-neutral cleaner is made with reactive agents and extra high-performance detergents. Superficial rust, metal particles, burnt-in brake dust, and other non-organic pollutants are swiftly and thoroughly cleaned away. Gentle for materials. Components are harmonized for a longer contact time/moisturization so the reactive agents can dissolve tough stains and burnt-in particles effectively. The cleaner, once it has dissolved the dirt, turns violet in color. The special surfactants in the formula coat and disperse the partially dissolved dirt, so it is easy to rinse it off.

Review: Smells Like Regret, Works Like Magic - I don’t know what ancient German spellbook KOCHCHEMIE pulled this formula from, but this stuff *obliterates* rust like it owes it money. One spray and the corrosion practically packs its bags and leaves in shame. The chemical reaction happens fairly quickly, pretty cool to watch. Let’s address the the smell. It smells like hot pennies mixed with expired pickles and sadness. You’ll question your life choices for a moment... but then you’ll see the rust vanish before your eyes, and all is forgiven. Worth the money, I wish there was more for the money but still would consider it decent value for the performance. Bottom line: it’s like a spa day for your metal parts. Absolutely worth the stank

Good naturalized a rust. It's not cleaning all way to metal, but requires little scrab to get in to metal.
