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. VOC COMPLIANT.
