That's it!! I took a trashcan, filled it with water and about a half box of "arm & hammer, washing soda" I got mine at my local wal-mart. Its with the laundry detergents etc. Cost less then $4.00 for a 55oz box.
You simply hook the part you want to clean to the negative cable. Hook the positive to a piece of bare steel, ie, not galv, painted, etc. Then just turn the charger on and wait 8 hrs or so.
I can supply more details if anyone is interested.
