I use a dinky little 12 volt charger with a 32 gallon garbage can. Works great. I was using a rubbermaid tub, decided I wanted to go bigger and stepped up to the garbage can. I used a bunch of scrap steel for the electrodes and have them wired together around the outside of the can standing up. I hang the part in the center and plug it in. My opinion is that there is no better way to derust and clean parts. I noticed a HUGE difference with the more electrodes I added. I have them spaced 6-8" around the can and the whole thing turns into a frothy mess within minutes.
I use arm and hammer washing soda. Soaking in this seems to degrease and soften the paint so that it comes right off with a wire brush or just rinsing. Granted, the stuff Ive been using it on has been sitting for 50+ years, but I swear by it.
Id say try it out. If you spend 6$ on a box of washing soda and a few gallons of water, are you really out that much in time and money? Id save buying an expensive tub until you try it and see how you like it. Just make a plywood box out of scrap and through a few layers of plastic in it if you need a container to fit.
This is a great example Jeff
