Anybody got a good cleaning solution for the non-body colored piece on the bumper around the exhaust tips? Mine has some grime/tar that car shampoo doesn't take off...This surface is kind of textured also...just wondering what you guys use. I guess bug and tar remover might do the trick.

 

It seems to get everything off when I scrub hard with a sponge. My next step would be the bug and tar remover but don't leave it on there for an extensive amount of time.
