Bilt-Hamber Auto Wheel

Still the best

This cleaner has a unique non-acid, non-alkaline formula, but it’s still powerful enough to shift tough dirt and baked-on brake dust.

Bilt-Hamber has added a strawberry scent to combat the eggy whiff we’ve criticised before, but it still doesn’t smell great. It’s easy to apply, though, plus you get more for your money.

The colour-changing formula shows how much road grime you’ve removed from wheels.
