Doyle said it before I could. I set up a small unit to run in my garage (Detached from the house). I used an old cell phone charger and an ugly purple tote my wife had laying around.
I did not believe it would really work, but was amazed at the pair of pliers I pulled out after just 24 hours. Heavier rust requires more time. Once you pull the equipment out of the solution wash it off, dry it and oil it.
WARNING: This can be fun and pretty soon you will be trying to either remove rust from everything or taking the next step and trying to plate everything.
