Removing agressive brake pad dust

[NightmareMoon]

My GLOC R6 (autocross compound) pads have really etched dust into my wheel paint on the fronts. I went too many miles without cleaning I guess on a road trip there.

whats a good cleaner which will help me remove it?

A good iron remover will help break down the ferrous part of it, think IronX or the like from any good company that carries it. Or even CARPRO WheelX is a wheel cleaner with iron remover in it. If it has already destroyed the clear, it may be too late though. I would apply to a cool wheel, let it dwell as long as you can without it drying, then rinse strongly with Pressure washer and evaluate. Apply again and agitate the second time with a soft bristle brush or a microfiber wash mit to see if you can break up some more. May have to resort to a acidic wheel cleaner after that, apply that with caution in an inconspicuous area before going nuts with it.

The poster above is correct^

An iron remover will loosen and remove what's there. I have had wheels with severely baked on dust(think seized caliper) which took multiple(It was years ago but I think it took 4 rounds at least) applications of iron remover. You can go ham with it, as they are generally pretty close to neutral on the PH scale, but don't let them dry on the wheel same as any chemical.

If your wheel is powder coated or clear coated you can also use wheel acid. This is more aggressive, but you need to be cautious with it. It cannot dry on the wheel or it may damage it. Rinse completely. Do not use it on bare aluminum, as it will immediately etch it.

If there is etching present from the brake dust(and it is very likely that there is from your description), then you might get everything off, but the clear/powder coat will still show some damage.

I know it's hard to keep on top of track wheels as the brake dust is constant and significant, but it's important to keep the wheels clean, or permanent damage can occur.

Thanks. They’re satin black and I’ve had them for like 9 years, one has already been resprayed, so a little minor finish damage is just water under the bridge at this point.

i’ll try the iron remover
