Hi,

I purchased a certified '05 A4 9 months ago and I am starting to see that my rims are discoloring. I have been taking my car to a well known car wash place ever since I got the car. Recently two my rims have started to discolor and it seems to be getting worst. Has anyone have the same issue? Any thoughts/suggestions? I am not sure if it the chemicals the car wash place is using but moving forward, how do i get this fixed?

Thanks for your suggestions!
