I've called the radiator shops locally who won't touch it. Any home remedies I could use? -David

But the most interesting way I've seen is GRSCUM's method here:http://www.modernvespa.com/forum/topic19209

If you do decide to media blast the gas tank you have to be really, really careful about cleaning it out afterwards. Clean it really well, then clean it some more because the media is extremely difficult to get out. Any little remaining bits will be washed down through the fuel system.

I've seen tons of carbs clogged with media because the owner had the tank blasted, thought they cleaned it out enough, but hadn't.

Personally, it would be the last method of tank cleaning I would ever use.

Did the local radiator shops tell you why they won't touch it? We get all our tanks done through a local radiator shop and the only time they won't do it is if the tank isn't worth saving because of pin holes or a really, really messed up inside.

They just said they only do radiators. Maybe I'll try the cleaner with nuts and bolts & some BB's then shake, shake, shake. -David

You get it at a tractor supply store. He said it worked just as good as the cleaners you buy.I know N.C. has tractor places.

This is by far the best and easiest. Save the left over Metal Ready stuff and you can derust more stuff as well. http://www.por15.com/prodinfo.asp?grp=CTRK&dept=11
