Turtle Wax Hybrid Solutions Rapid-Decon Iron Remover is a 680 ml colour-changing spray that safely lifts embedded iron particles, brake dust and rust spots from your vehicle. The acid-free, fast-acting formula turns red as it reacts with contaminants, so you can see it working before rinsing away. Safe for wheels, paint, polished metal, chrome and glass, it deep-cleans and preps surfaces for waxing or coating. An effective decontamination step for a smooth, clean finish.
