I believe you not going to be able to fix the crud problem you have with the wheels easily. The problem in most cases is the clear coat powder coating has microscopic cracks that allow moisture to permeate through and the aluminum starts to corrode. Higher quality wheels like Alcoa use higher quality materials and this is not as much a problem. I had the same problem on my first set of wheels and I called the wheel supplier and sent photos of all the wheels showing the 'crud' you describe. They sent me a full set of replacement wheels and I returned the bad ones to them. I had to pay mounting and balancing but all other costs were covered. It does not cause the wheel to be less strong, only unsightly.

The costs to refurbish these wheels could be in the 100 to 150 dollar range, each, and you would be without them for upwards of a week. In my past life I did hundreds of them and in most cases it was just easier and faster to buy new. The clear coating is very hard to remove without the proper equipment. The powdercoating is also a expensive process if done correctly.
