I got these knuckles from the junk yard. They are old and really rusty so I want to clean and paint them with ceramic paint. Ok, no big deal right?
Wrong! They are really rusty and just all around crappy and to clean them would take forever.
I think to my self - I wonder if electrolosis would work?
So I get a cheap plastic bin from big lots, A 99 cent box of baking soda, an old battery charger, A junk chevy truck rotor, and some water.
I fill the bin with water, then dump in the box of baking soda mixing it in. Clean off a spot to hook the clamp from the battery charger on the rotor and set it in the tub of water. Then I cleaned a small spot on the knuckle to hook the other battery charger lead. Put it in the water.
Stand back and plug in the charger........ Well the charger loaded down as it should and within seconds i could see bubbles coming from both pieces of steel.
I could not remember which lead to hook to the sacrificial piece so I moved them around after a few minutes and got them right.
So the thing has been setting for about 4 hours. The water now looks like sewage but it is working great.
So if you ever have any rusty metal you want cleaned with out expensive chemicals or lots of elbow grease, give electroliosiss:grin: a try.
I'll post some before and after pics when it's done.
