Polishing stainless exhuast

[danw]

I generally go over the pipes whenever I get serious about cleaning the rest of the car. It's a lot less often since I resealed the collector connections a couple of years ago.

I use Muriatic acid purchased from Lowe's. This is what I do. Make sure the pipes are cold. Take a paper towel and put some Muriatic acid on it and clean the pipes off. Then soak a couple of paper towels in water, don't ring out the water, and completely rinse the pipes. Now use a couple of dry paper towels to dry the pipes. I don't use gloves at all. The acid is very mild. Now I use a stainless steel polish to finish if needed. Both side can be done very quickly.

I used Flitz Polish on my stainless steel roll bars that I had welded up. They had blued from the welding and Flitz removed it, I was very surprised. Works great!

Aj,
I picked it up at a local paint supply house and I've seen it on autogeek.com as well. It's not cheap, but works really well.

Looks like I have something to do this weekend. Scott I'm assuming you mean Auto Paint supply store?

Using Muriatic Acid also known as another name for Hydrochloric Acid HCI, is a peroxide base and will remove the Chromium Oxide layer and over time pit the base metal if using it undiluted. Once pitted, dirt and other metals will adhere to the pitting and rust eventually completely through.

HCI is mostly used to pickle steel.
