Go figure... Today the passenger side airbag sticker fell off the visor. But, this is on a S550 MERCEDES. First of all, I hate these stickers to begin with, but now that it fell off, the area is darker and the glue from it the visor left a perfect square. I guess I have to put this ugly thing back on? I can't believe there isn't a SAFE way to clean the visor fabric so we can just leave it off..
