Iron and Fallout Removal. Highly recommended prior to any machine polish or wax application. This will remove any of the airborne contamination that will sit and embed itself into the paint causing corrosion over long periods of time. You can see it on white vehicles easier as it will be orange rust coloured spots that just won’t come come out every time you clean and will definitely be visible on the rims if they are not subject to regular maintenance. We use specific chemicals designed to tackle this by turning it from solid state to liquid state. This can be visibly seen as it will turn red in the process also known as bleeding.
