Remove surface rust, burned in brake dust, and iron contamination from paint and glass in minutes. RRR quickly breaks down contamination and draws it out as it works. It is formulated to tackle the material that embeds itself in the clearcoat and will not be removed by a normal wash. The active ingredient turns red or purple as it reacts with metal particles so that you can see just how hard itβs working.
Spray undiluted on entire vehicle exterior and let sit for 3-5 minutes and rinse off.
