Default Re: Muriatic Acid for Gas Tank Cleaning

I just rinsed a super crusty tank in vinegar and it came out super shiny and sexy. I let it sit for about 48 hours and it really did a great job. The other benefit is that vinegar is very easy to dispose of when you're done with it. Its not near as harsh as muriatic acid so it doesn't flash rust quite as fast. I took some pictures of the process and I'll see if I have time to post them sometime today. I soaked it it in vinegar (mild acetic acid), neutralized it, and put it in the oven at about 200 degrees for a while just to make sure it was dry inside so it wouldn't flash rust again. Sounds like one of those urban legends, but it is by far the best thing I've found for it. Muriatic acid tends to work much faster, but flash rusts immediately and is tougher to get rid of when your done.
