Tank Cleaning by Electrolosis.

bad assed, super fast and fully gassed
So i dunno if anyone has ever posted on this subject or not here, but here goes.

Tonight I took a stab at the electrolosis rust removal ive read about on a couple of forums. The set up is remarkably simple, and tho its only been doing its thing for a couple hours now, already its going to town.

Set up, as i said, was cake. Removed the petcock, as the aluminum in the petcock would quickly be destroyed by the process, and sealed the holes with a piece of sheet steel and a piece of rubber inertube. Sealed pretty good. Lil bit of a SLOOOOW leak, but i dont think it will seal any better temporarily. Once that was done, i filled the tank with water and some Arm&Hammer Super Washing Soda. Some have said baking soda will work, some have said it wont, MOST have said this stuff works better. They say a couple tablespoons will do, i just eyeballed it. You can find it in most laundry detergent aisles at the local megagrocerysmallwaresstore. (ie Kroger, Albertsons, Meijer and the like) I had a couple of bare (NOT COATED) wire coat hangers around, so i cut them down and bent them so that the wire would NOT touch anything on the inside of the tank. I then poked a hole in the top of a rattle can cap and ran the hanger thru, and bent it so it would not move. Slid the hanger in, secured the cap on top with some tape to assure it would not shift and allow any grounding out, as the process causes air bubbles that are violent enough to move the hanger, and connected the Negative clamp of my trickle charger to the tank body (just about anywhere will do) and the Positive to the hanger. Before plugging the charger in, i assured that i had infinate resistance with an Ohm meter, and plugged it in, then checked the amperage draw. Just about 1.25 amps, my charger is rated at 1.5 so good enough. They say 2 amps is nominal, but this seems to be working just fine.

Bout an hour went by and i gave a look. WOW, something is definately going on in there. Water is nasty, green and filmy, with some rust colour floating on top. I unplugged the charger and pulled the hanger out, and it was already coated pretty well with crap. I did notice that the last time i checked, the current flow had dropped considerably, as the anode was completely covered. Cleaned it again, and current flow was back up to 1.3 amps. Figure if i check it a couple times a day for the next few days, i should have a reasonably clean tank in 2 or three days. I'll keep ya posted :) ;D
 
Umm thats smart's!!!!!!!!!!!!easier than shakin the tank with gravel!!
 
Thanks for posting this TonUp, I'm considering doing it on a plethora of parts at once, perhaps in one of those cheap kiddie pools.

I do have a strange fear of electricity, so I'm going to read up on the process very carefully before moving on with it.

Love to see some pics when you get a chance.
 
Well its a bit of a slow process, but what kind of pics would you guys like? Of set up?

Its been a few days, but i dumped the water and whatnot a couple of days ago. Its pretty damn clean! Unfortunately, it involves ALOT of rinsing to get the crap out of it, and i wasnt thinking it thru, and didnt rinse the tank with alchohol after, and ive got a couple of water surface rust spots back, but nothing like it was. I think i will set it up again, just for a day to take care of that, and then rinse with the alchohol to assure that it dries water free. I will get some shots up of the set up.

One thing, some people who've done this say that their "smart" chargers dont work, because it senses that the "battery" is full, and wont produce current. So you may have to pick up a cheapie dummy charger, depending on what type of charger you have. I used a semi-smart 1.5 amp trickle charger and it worked well.
