Know there's got to be a thread about this already, but couldn't find it using my iPhone app here.
I washed my '12 JKU Sport earlier today. It had mud on the rear plastic fenders for about a month now. I had to have scrubbed for about 10 minutes on each of them, both with sponge and bug sponge. They look clean when they're wet, but as soon as they dry, I can see the dirt again like they're stained.
Any ideas? I know I read something about how to get rid of the stains and take care of all the black plastic parts.
