Bilt Hamber Korrosol is a non-acid, non-alkaline fallout remover for the safe and effective removal of embedded metallic particles that contaminate the vast majority of road going vehicles. You may not have noticed by looking at your paintwork, but next time it's washed and clean lightly feel the paintwork, especially the horizontal panels; bonnet, boot lid, roof etc. Very gently with finger tip touch you'll be able to feel a rough grittiness. You may well think this is dust landed from the air – it's not. Airborne metallic particles liberated by braking surfaces, such as pads and discs fill the air along our roads, when hot after the car in front of you brakes your car travels through them, as a result they embed themselves in your paintwork.
Here they react with rainwater or air moisture and begin to corrode and as the corrosion product (rust) occupies four times the space of iron the paint is slowly ruptured around the embedded particle. This action destroys both the aesthetic and protective qualities of the finish.
While harsh acids such as phosphoric and oxalic acids maybe use with good effect to remove the contamination, these acids to not discriminate between corrosion and good steel not even paint films themselves, so while the particle is removed and base metals or coatings can also be attacked. Korrosol's effective formula is simply sprayed onto the contaminated panel a rapid and dramatic colour change takes place which indicates that the corroded part is water soluble after which a rinse with water leaves the panel free of metallic embedment. Korrosol is safe to use on all auto body paint finishes including lacquers.
Wash the area first to remove any surface dirt, then liberally spray the contamination with Korrosol. Allow to dwell for upto 5 minutes. During this time you will observe a colour change where Korrosol is working against the fallout. Rinse thoroughly with clean water. During hot weather reduce dwell times to reflect the increased surface heat.
