Koch Chemie Felgenblitz Säurefrei (FB) is a pH neutral wheel cleaner that reacts with brake dust, lifts grime, and leaves wheels clean with a hydrophobic finish.
Felgenblitz Säurefrei takes wheel cleaning further than most products. The pH 7.5 formula is completely acid free, making it safe for aluminium, steel, and chrome finishes, while still strong enough to dissolve the kind of stubborn contamination that builds up over time.
The gel consistency is what makes it different. Instead of running off straight away, it clings to the wheel, giving the chemistry longer to react. As it works, the product changes colour to a deep red, showing you it’s breaking down brake dust and iron particles that regular soaps won’t touch.
Once rinsed, it doesn’t just leave the surface bare. The formula adds a mild hydrophobic effect, which helps water bead and reduces the chance of dirt sticking again. That makes ongoing maintenance easier and keeps wheels looking cleaner between washes.
For detailers and enthusiasts alike, it’s a dependable choice when you need an alloy wheel cleaner that combines power and safety. Whether you’re maintaining a daily driver or tackling neglected wheels, Felgenblitz Säurefrei delivers consistent results. It works equally well as a rim cleaner for deep decontamination or as a ready-to-use car wheel cleaner for routine washes.
