I was wondering if anyone else has pitting on the inside of the rim as a result of the road salt. I clean my wheels once a week (even if I can't wash my entire car due to wet weather) primarily because of the substantial brake dust. After the first snow storm, I noticed areas on the inside of the rim that I just can't get clean and it is slightly pitted holding in the brake dust. I use Westly's Bleach White and have also used Meguires Hot Rims. Neither one do the trick and I am reluctant to try anything harsher so that I don't make a bigger and uglier mess. I have a call into the dealer to see what they recommend. Some call me fastidious, but I like a nice clean wheel.
