Reactive™ is an advanced pH-balanced, non-corrosive cleaner formulated for fast and effective removal of iron deposits and brake dust from all painted finishes and steel, chrome, alloy & clear coated wheels. Reactive™ targets iron-based contamination and safely breaks it down for quick removal. Ready to use, Reactive™ sprays on clear, but turns purple as it comes into contact with iron particles. Contaminants can then be rinsed freely from all exterior surfaces. Lemon fragrance. Available in quart and gallon sizes.
