Who cleans the plastic wheel skirts? I'm asking because my lovely wife that she was in the jeep and hit a mud puddle. I know I'm gonna have to pull the tires to really get in there, but I guess I am asking what would you use. I'm hoping good old fashion soap and water and elbow grease does the trick. And I've heard to spray the liners with Pam and things doesn't stay on??? Thanks anyone with a good tip.
