Help Cleaning Exhaust

MuffinMan910 · 08-19-2014, 05:11 PM

so my dealer switched out my left exhaust under warranty because the flap was rattling on cold start. i bought this car a month ago and the previous owner took amazing care of it, but never cleaned the exhaust. so now i have one brand new exhaust and one covered in black soot.

i managed to clean it somewhat with tar remover, and mothers metal polish but its not coming off easily. any advice anyone?

Steel wool works good. I did it on mine and they look new

Steel wool, chrome polish, and a good scrubbing should work.

I've heard coke (or any carbonated soft drink) can be used also, but I've never actually tried it.

Fine grade steel wool and metal polish.

Coke or Pepsi and a toothbrush, that's all you need.

I use Meg's ball polisher with some metal polish.
Using a drill makes it way easier than by hand.
Unfortunately, this only lasts for a few weeks.

thanks for the advice everyone. i tried coke… didn't do a thing. i also tried baking soda and vinegar.. that helped a bit. ill try steel wool next then the ball polisher. I'm not familiar with the grades of steel wool? which one would i need to prevent scratching?
