ELECTROLYSIS RUST REMOVAL

An easy and relatively safe method of rust removal is the use of electrolysis. It involves a few common items that can be scrounged or bought quite cheaply.

Parts needed:

• water
• washing soda (sodium carbonate)
• a battery charger (with a current meter if possible) or a car battery
• steel or iron electrode (I use rebar as it's cheap and the anode will eventually be eaten away)
• a plastic tub (slightly larger than the part to be cleaned, although it is possible to clean a part with some of it sticking above the solution and then rotating it to clean the rest it may leave a small mark or discoloration which is undesirable)

**Caution** Hydrogen gas reacts explosively with oxygen (in the presence of heat) to produce water vapor. Take Michael Sullivan's advise seriously about shutting down the power before adjusting/removing the electrodes.

If you are using electrolysis to remove rust...and have a considerable broth of bubbles...be very cautious. That broth is not the place to discard a glowing cigarette ember, lit match...or any other spark. Be warned...!!
