Possible solution to baked in track pad dust

str8shot · 05-30-2012, 08:49 AM

The PO of my car had some Hawk DTC-70s installed before I bought it (which I swapped out for HPS's).

There's some pad compound imbedded in the wheels I just can't get off.

I used a buffing wheel with polish and actually started to burn through the paint on the inside of the wheel...this stuff just isn't coming off.

I was preparing to repaint them, when I came across this:

Anyone ever use muriatic acid or HCI to clean their wheels?

I think I'm gonna give it a shot. Worse case scenario I'm repainting them anyway...

Depending on the concentration, it will eat the paint.

Maybe if you left it on over night. Did you follow the link? Looks doable to me.

I doubt STI wheels are any better than BMW's...

Try Sonax wheel cleaner. Amazing stuff.

Muriatic acid is formulated to clean masonary (concrete) not auto wheel surfaces

Sonax Wheel Cleaner full effect - the best of both worlds; the cleaning power of an acid wheel cleaner with a (safe) pH of 7.0 by using a neutralised acid salt; neutralization is the reaction between an acid and a base (alkaline) producing a salt and neutralized base; common examples include acetic acid and sulphuric acid (hence the red colour, which is a chemical reaction (oxidation) with the metal particles) and the smell (sulphur) This product safely encapsulates the iron oxide (brake / rail dust particulates) to enable it to be rinsed away

Are you sure you don't mean Hydrochloric acid, or HCl (that is "H" "C" and "L")? Hydrochloric acid is a strong acid, made of hydrogen (H) and chlorine atoms (Cl).

The STI owner said it didn't hurt the clear coat on his wheels.
