I had some serious exhaust stains on the bumper and the sides werecovered in brake dust that would notcome off with ordinary soap, water, and elbow grease. While shopping at Lowes I picked up this stuff called Krud Kutter and was absolutely amazed by the cleaning power and best of all its biodegradable, non toxic, NON-FLAMMABLE, NON-ABRASIVE. It was a little pricey about 6.00 per bottle but man does it ever clean. Any way if your using some dusty track pads or running a straight pipe I highly recommend this stuff to clean up the damage.

Nice find, thanks for sharing!

 

Thanks for the tip!

 

Bug & Tar is also really good stuff.

 

if you ever get a chance or hear of this wax called astro shield get it. it is the best wax i have ever used it's a little expensive though but it lasts up to six months and you don't have to work very hard on washign your car cause dirty and stuff comes right off i love it.

 

i sparingly use Castrol Super Clean on the blask soot stains on my bumper. But you gotta be really careful with this stuff or it'll eat your paint!.

 

Paint clay (available from Mcquires or Griots) does wonders for both, and won't harm paint.

 

moving this.
