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.
How to use:
Bilt Hamber korrosol comes pre-diluted to the correct strength for safe exterior use. In all cases, wash and rinse the surfaces you are going to treat in the normal way. Next, working on 3-4 panels at a time, spray Bilt Hamber korrosol on liberally and allow 3-5 minutes for it to work; during this interval the initially transparent solution will gradually turn a deep red as ferrous compounds and sintered iron particles dissolve into solution (this effect can be very pronounced, but don't panic because it's quite normal and to be expected). Although Bilt Hamber korrosol is essentially a touchless cleaner, you can agitate it with a microfibre towel if needs be (we recommend using a PB Disposable Towel). After 5 minutes or so rinse the surfaces you have treated with a strong stream of water. Note that if the solution has begun to dry you may need to use a stronger jet of water from a pressure washer to remove the residue. After rinsing off, check the treated surfaces for residual contamination by running your fingertips over them while they are still wet. Contaminant-free surfaces should feel perfectly smooth (if your fingertips aren't particularly sensitive you can magnify your sense of touch by putting your fingers inside a cellophane wrapper first). If you can detect any grittiness then it's likely that the treated surfaces are still contaminated with non-ferrous particulates (e.g. paint overspray) and will need to be carefully clayed before any polishing is done or any protection is applied.
