Put new WWWs on the bike this weekend. While I have the wheels off I need to clean and polish the rims, so I bought some Meguiars Hot Rims mag cleaner and polish. After putting a nice shine on the front rim I clean the white walls and to my shock every place the polish touched the white walls it was a really nice blush pink! I spent the next several hours and every product I could think of trying to get the pink color out. I finally got to the point where it wasn't as bright and gave up. Now you really don't notice it unless you look very closely so I suppose I can live with it. The Meguiars Hot Rims did a nice job....just DON'T get it anywhere around white wall tires!!
