Cleaning inside exhaust tips - getting rid of black carbon

6MT · 03-14-2011, 08:32 PM

I use a bug sponge, warm water, and a good car wash soap. The bug sponge is rough and it works extremely well without scratching the finish. My Stillen tips do show some blackness and this technique works well for me. I also don't leave them very long between cleanings (a good practice).

Scotch-brite sponge sold in the kitchen supplies section of any grocery store. I usually use the course side of the sponge and some simple green, works great. Sometimes there's black spots that won't come out, in that case a light rub with some red scotch-brite works good. This applies to just the inside of the exhaust tips. I use the same sponge on the soft sponge side with simple green to clean the inside of the wheels behind the spokes.

thanks for all the suggestions....i'll try the sponge method...thinking of trying the "purple stuff" which i happen to have a bottle of and warm water.

I'd watch that purple stuff. I'm not sure if it's just me or what, but the purple power stuff seems to really stick to my hands and after about an hour after using the stuff I have lizard skin. Simple green seems to have the same cleaning power but to me is just alot less corrosive on the skin. I haven't seen any ill effects on metal, but I know it does a number on my hands.
