You also have to watch out for certain wheel cleaners. I have tried soooo many cleaners to try to get the brake dust off, and one of those cleaners have made my 8 spokes spotty. It looks like the finish is starting to wear off. I always used a soft sponge when cleaning, but I think a harsh cleaner(I think it was Meguires Instant Wheel Cleaner, or their Hot Rims Cleaner) is what did it. I currently use Simple Green in the aerosol can, and it works great. I may have to take Big Jims advice and wax them. Do you think that would help my wheels look less spotty?
