Chemical Guys DeCon Pro Iron Remover and Wheel Cleaner is formulated for gentle cleaning action on the most common areas of iron contamination and pollution. Use DeCon Pro to release hot iron deposits from paintwork, polished metals, wheels, brake components, undercarriage parts, glass, and lower body panels closest to wheels and brakes. DeCon Pro is pH-balanced, non-caustic, and safe for all shiny and glossy wheel and paint finishes. Iron particles can cause abrasive swirls and scratches from improper removal, but they also break down painted finishes and promote rust and corrosion. Even after the particles are removed from paint, the reaction has started and can continue to destroy painted finishes on any vehicle. DeCon Pro actively neutralizes the chemical reaction in its tracks and stops corrosive damage from hot iron deposits before they cause total paint failure.
