I have a rather ugly looking set of the older 10-spoke OEM alloys. I took two of them to a car wash and coated them with "Aircraft Stripper" from Auto Zone. Left it on for about a minute, then fired up the spray wand to rinse it all off. The stuff works very well, but I was in a hurry and didn't get 100% coverage, so I will go back, with all 4 wheels this time.
I went to a self-serve car wash because the stuff is acidic, and I wanted to be sure to rinse it all off. I don't have a power washer and I didn't want the acidic solution on my driveway, so the car wash seemed like the next best idea.
There is some pitting and discoloration under where the weights were. I'm buffing that down with crocus cloth and then aluminum polish on number 0000 steel wool. Once I have the wheels cleaned up, I'll try coating with rattle can clear coat.
