Bilt Hamber - Korrosol Iron Remover
Bilt Hamber Korrosol is a controlled pH 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.
Once on the paintwork, 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.

We Say
“Our honest view, based on real-world testing and day-to-day use.”
Korrosol is one of those products that has earned its reputation through consistent performance rather than clever marketing. It’s been one of our best-selling fallout removers for a long time, and much like most Bilt Hamber products, it tends to sell itself once people see what it can do first-hand.
From a technical standpoint, Korrosol uses a reactive formulation that targets embedded iron particles and industrial fallout, converting them into a water-soluble residue that can be safely rinsed away. The familiar colour-change reaction isn’t just for show — it’s a clear indicator that contamination is being actively broken down at a chemical level.
What we particularly like is how effective it is without being unnecessarily harsh. It works quickly, clings well to vertical surfaces, paintwork, and clear coats when used as directed. That balance between strength and control makes it suitable for both routine maintenance and deeper decontamination work.
Considering its performance and coverage, it also represents excellent value compared to many alternatives in this category. For us, it remains a dependable, no-nonsense choice for anyone serious about keeping paintwork and wheels properly decontaminated.
