I am looking for the easiest way to clean my fenders wells so they are black again rather then dirty and white-ish from road salt, I usually just wash it like I do the rest of my car but then it drys and isnt as black as I want it to be and also how to remove the white color from wax that had gotten on my mud flaps, how to remove that as well

For deatiling wheel wells I use this http://www.griotsgarage.com/product/car+ca...vals&page=1

or sometimes use just regular armorall spray but doesn't last nearly as long as the Griots and to remove dried on wax I use this http://www.griotsgarage.com/product/car+ma...vals&page=1
