Iron Buster Wheel & Paint Decon Remover is a colour changing, fast acting, pH balanced cleaner formulated to safely dissolve ferrous particulate from wheel and painted surfaces. Iron Buster will safely and effectively remove embedded iron particulate along with other contaminants from wheels and painted surfaces. Once applied Iron Buster will change to a purple colour when iron particulates are present and then a rinse should be followed for a clean surface. For paint - Wash and dry surface prior to product application for maximum effectiveness. Pre washing for wheels is not required. Once surface has been prepared spray a generous amount of Iron Buster to the paint and/or wheels. Allow product to dwell for 2 - 3 minutes. Do not alloy product to fully dry on surface. Rinse thoroughly with water using hose or pressure washer. Repeat process if necessary. For a full deep wheel cleanse follow with P&S Brake Buster.
