Muriatic Acid Rust Removal
Muriatic Acid Rust Removal | eHow.com
I get the stuff at the hardware store. Used this stuff to strip the firewalls of rust etc on old cars. Suggest reading up on this stuff before using it tho.
Pickling a part in Muiratic is important first step prior to plating with copper, then Nickel or chrome
HOWEVER! iT CAN BE DONE ELECTRONICALLY.GOOGLE "electrolytic rust removal:
POUR A TEASPOONFUL OF BAKING SODA (OR WASHING SODA)IN A STURDY PLASTIC OR GLASS VESSEL.
1. Hook the negative 12V to the rusty part and
2. HOOK the positive to a steel bolt or a piece of steel chain immersed in the bath, making sure all is immersed.
The electrolytic process will plate out all your rustto the steel bolt/CHAIN anode.
I used a 12V DC CB power supply but a car battery will work too, even lantern batteries.
