As we drive our cars, they are continually bombarded by metallic particles that fill the air along our roads and beside our railway lines. These particles are often extremely hot, having been discharged from braking surfaces, and as we drive through them they embed themselves in the bodywork by melting their way into the surface of the paint. As they accumulate, these particles form an increasingly rougher surface that dirt and grime readily adheres to, thus making our cars harder to keep clean. Moreover, as they are mostly iron-based, they readily react with moisture and rapidly corrode, which degrades both the aesthetic and protective qualities of the paint finish further. Bilt Hamber korrosol is a fast-acting fallout remover, designed to effortlessly dissolve all iron-based contaminants without the need for any manual agitation. It's formulated to offer the same level of cleaning power as highly acidic fallout removers, but without any of the associated safety risks. Highly acidic fallout removers work by attacking iron-based particles and reducing their size, which releases them from the paint surface. They are certainly very effective, but they attack underlying panel substrates if the paint system is compromised (by stone chips or other penetrating damage). Bilt Hamber korrosol works differently, by using a neutralised acid salt to render the iron-based particles water soluble, thus enabling them to be safely rinsed away.
