Left my track pads on from last year and took car for a service. Going to a DE at Summit Point Mar 9-10 so not going to swap to the street pads. I normally use a wheel wax and wash the next, but didn't realize how much dust I had generated for the short maintenance trip. Wheel cleaner removed most of it but several "corners" have hardened areas of brake dust I can't even scratch with my finger nail. Any suggestions welcome.

Iron X - spray it on.. let it soak for about 5 mins and then agitate it with a soft wheel brush and then hit it with a pressure water.

WD40 is my go to, it is a cleaning spray after all. Then thoroughly rinse with water afterwards.

I've used Muriatic to etch my floors (and treat my pool) and I'd be nervous to get that anywhere near my car. Seems pretty fast acting.

Do you have any pictures of the residual dust you're trying to remove? (That is not coming off using conventional methods.)

I'm a big fan of Sonax. It's non-acidic and dissolves the caked on stuff.

I would stop at a local BMW dealer and buy their wheel cleaner gel. It is actually an iron remover designed to actually pull the pad deposits out of the wheel. It is my go to for caked brake dust and it's actually reasonably priced. I did this with a towel only as it was at the shop and I didn't have a wheel brush with me.

Clean! Sonax is the same thing, and probably 1/2 the price of what a dealer would charge. You can get it at most auto parts stores.

Surprisingly the wheel gel is the cheapest thing I've ever seen with a BMW logo on it. It's only about $10-12 a bottle

Iron X gel for stubborn areas that need a longer dwell time.

Follow directions and use multiple applications if necessary.

Then wash wheels traditionally after to remove any residue.

BMW gel cleaner just arrived from Amazon Prime. Sprayed a test spot of hardened Hawk 60 brake dust. Let it set for an hour. Just checked it had partially dissolved the dust spot and it easily wiped off with a paper towel. Will do the rest on a better weather day.
