I went to the auto parts store today and picked up Eagle 1 Nevrdull as Andrew recommended. I love this thing. I never thought I would be cleaning the black stuff off the exhaust pipes. But I cleaned my XF, my wife's X5 and my Avalon's tailpipe. I'll post the pic on my gallery. Now my tailpipe is just as clean as Andrews.
