What is the best method to remove this type of brake dust:
?
The brake dust feels smooth as if it melted into the wheel.
I've tried P21S Gel Wheel Cleaner, Sonax Full Effect Wheel Cleaner, and clay with no luck.
So I pulled out my PC with a orange LC pad and used some APC (S100 Total Cycle Cleaner) and was able to achieve the above results after a couple of hours.... and still not done!
Is this safe for my stock oem wheels or am I damaging them?
Any other ideas that I can try out?
