Decontamination is an important part of detailing for anyone serious about preserving and maintaining the finish of their vehicle by removing paint contaminates.Tiny metal shavings from rail dust, brake dust and industrial fallout, as well as tree sap can contaminate and actually have a negative affect on painted surfaces, slowly damaging it over time. Iron Fallout Removers and Clay bars are the most widely used methods for decontamination. The most noticeable benefit of using a clay bar is the slickness and smoothness of the painted surface, allowing waxes and paint sealants to bond or adhere to the more effectively. A fallout remover is a special product aimed at decontamination that has the chemical ability to help remove iron-oxide particles from a surface without having to remove them mechanically. These particles are loosened up via a chemical reaction, turning the contaminants purple/red and allows for them to be rinsed off safely.
