Short version:
Materials needed:
Plastic bucket/container
A battery charger (preferably an older "dumb" one with a real transformer)
Spa chem PH + (spa/pool chemical) or washing soda (Arm and Hammer?)
Some iron/steel (NOT SS!) for an anode (rebar works great)
Some iron wire to connect to the submerged parts, (small parts I often suspend in the bucket from a cross bar and the wire)
And set it up like this:
I often use a 5 gallon plastic bucket, and fill it near full with water 4-to 4-1/2 gal?) not critical...
throw in about a handful of the PH+ or Washing soda.
Set up some anodes, (you can use wire to connect them together)
Make sure the part does not/will not touch the anodes, and connect the charger leads. turn it on and look for bubbles to start forming on the part.
If bubbles are forming on the part, go work on something else or go watch the game…
4-8 hours later check on it. it will likely have the water surface covered with a nasty red scum/foam, you can scrape/lift this off if desired.
As the water evaporates over days/weeks, of use (or non use) just add water, you don't need to add the PH+ it does not evaporate...
tons of info available on line, just Google "electrolysis rust".
Last comment anything in the "soup" needs to be iron or common steel; no plating, chrome, copper (wire) and definitely not SS!
The left over residue is an iron rich soup and is safe enough to add to your garden for iron/alkaline loving plants...
I will get some before and after pictures. THANKS SwampCat.
Thou shalt not put ANY plated or stainless steels in the Etank!
