Chemical Guys DeCon Pro Iron Remover and Wheel Cleaner is the specialty colour-changing gel that removes stubborn brake dust, iron deposits and other embedded metallic contamination from wheels and body panels before they can destroy your car!
 
Powerful brakes on modern cars spit out large amounts of hot, corrosive and filthy brake dust all over wheels, brake parts and lower body panels. The hot iron particles embed into the surfaces, causing a chemical reaction that leads to rust, scratches and swirls that cannot be fully removed by normal car washing techniques.
 
DeCon Pro releases iron deposits and other ferrous metal from wheels and lower body panels, then neutralises the corrosive chemical reaction that leads to rust and paint failure. DeCon Pro sprays on clear, then turns purple once the specialty iron catalysts react with ferrous metals and the chemical reaction releases embedded contamination so you know when to remove it.
