I've been trying to clean these wheels that have discolored. I went out and got some A2Z, and while that did a great job cleaning the brake dust and grime, it didn't do anything for the discoloration. I've posted a picture of what I'm talking about. The rest of my wheels look pretty much the same. I'm going to guess theres nothing that can be done, but I thought I'd see if anyone has any advice.
