Does anyone use this method to clean up parts and pieces? I have been going to try it for the things the salt seems to get to every time year after year.

My machinist buddy Jim does this all the time.....works great. He claims to have seen an antique tractor frame cleaned in a small above-ground pool,using an arc welder for the current supply with a whole bunch of washing powder dumped in. Guessing you need to keep the kids inside for a week or two. Jerry :-o

I'm getting ready to try this, here is a short video demo. http://www.metacafe.com/watch/456478/rust_removal_tip/

I tried this on a whim, just to see if it worked and I'll be damned did it ever. I used a small battery charger, a 5 gallon bucket and short rebar rods placed around the outside. Filled it up with water and baking soda (couldn't find any baking powder local) and it worked excellent! I wonder how well it would work if I did it right?
It works best on pieces that are absolute balls of rust. It cant make metal appear when it's already gone but it does make all the rust go away eventually.

We had terrible rust issues with the Breedlove car left un-preserved in Rio Vista for 10 years. The inside of the fuel tank was disaster. We used the POR-15 system of caustic cleaner / muriatic acid-phosphoric prep / sealant. We had to go back in and make a weld repair later and it took an air chisel to get the stuff off.
