He even dis it to top of his table saw with a rag.

I have heard negative comments on the use of a battery charger because it is somewhat unregulated and you can't attenuate the current - - -but if it's what you have at hand why not?

I have used electrolysis many times on my old tractor parts, it works great.

I used some phosphoric acid on my cast iron table saw top to remove surface rust. I then wiped it down with WD40. I need to clean it a little more with some scotch-brite and then wax it.

Thanks for the link, pretty interesting idea with the rag.

Don't know if "Baking Soda" will work. Usually "Washing Soda" is use. Not the same as Baking Soda.

There are a few of folks over on Woodnet in the handtool forum who use electrolysis for cleaning up old planes and such. A good source of info for any who are so inclined.

So ya think that is a typo?

I have used a battery charger with the baking soda solution in a plastic bucket (no real need for washing soda) to de-rust small tools. But that is really clever using a wet rag to do the tablesaw top. I just hope my top never gets that bad. Once I used a piece of dirty metal as an electrode that I thought was steel to do a stainless steel (yes, it does rust) soap rack. Turns out it was actually brass, and I partially copper plated the rack.

I just tried it with Baking Soda.
a cup some water a rusty old wrench some baking soda and a battery charger.

Worked like a charm.

I tried a couple different electrodes copper, galvanized steel and bare steel.
The copper seemed to sublime into the water the fastest.
