sdalcher Posted July 29, 2007 Share Posted July 29, 2007 I ran across a technique for removing heavy rust from steel and iron. It consists of filling a nonconductive container with water adding sodium carbonate (pool additive to raise PH) teaspoon per gallon of water. You then attach a battery charger (car variety) negative electrode to rusyed part and then attach positive electrode to a piece of scrap steel. Caution are to wear protective goggles, do not allow the + and - charged parts to touch, dont reach in the water while connected, etc and use in a well ventilated area as hydrodgen gas is a by product. Supposedly this process will not harm the base metal, no matter how long left in process. I have several old sets of tongs that I would like to treat. I picked ouy the rusyiest set and hooked them up. Witin 10 minutes I had bubbles forming. After a couple of hours there was already a noticeable difference, I can't wait to see what they look like in the morning. Steve Quote Link to comment Share on other sites More sharing options...
