Just bought a 8300 miler Commemorative Z06. Removed the wheels for detailing and noticed on the inside of each aluminum wheel are these dark spots. Cleaners I have & tried to remove them just didn’t get the job done. Attached couple pictures. If knowing how to get these removed I’d welcome all comments. Thanks
Yes I tried aluminum polish without success. Not sure, but wouldn’t think they would clear the inside of these polished aluminum wheels? Trying on using 3x’s strength vinegar with 00 steel wool this weekend on them. ( saw that successfully done on YouTube. Will advise if that works. Been told hydrochloric acid could work also…..
Try ammonia or WD-40 first. If it is road tar, it will come off
My first impression was it looked like road tar. But after blowing up the pictures. It does look like something is going on with the clear. Hard to say for sure.
it looks like corrosion and/or pitting to me. Use your fingernail to determine if it is on top of the surface or below? If below it won’t polish out.

It definitely looks like corrosion snicking under the clear and it looks like it is in paint also. I guess you can only expose the aluminum with gentle blasting and then paint + clear them back. If you soak them in some corrosive product, it will just make it worse IMHO.
good luck.

Just ordered a gallon of “Iron remover” from Adams Polish to see if does anything plus for me. The 3x Vinegar /00 steel wool didn’t do anything.
