Guest guest Posted October 8, 2011 Report Share Posted October 8, 2011 After awhile you will find most metals like copper wire, silver, or stainless steel will form a coating or " oxide " that tends to reduce the electrical flow or " conductivity " in them. It reduces somewhat the amount of current by reducing how easily electrons flow out of the wire into the sponge or cloth and into you. You can remove it with steel wool, but if it is still pretty weak, you might add a pinch of baking soda (i said pinch) per cup of final rinse water for wetting sponges. Only a tiny amount is needed in plain water to bump up the conductivity quite a bit. You will more than double the power usually by doing this, so go easy. Baking soda in these amounts is very minor and most of it gets in the sponge, only to be washed away later. So relax about it. We used to use salt but found baking soda did the same thing without causing itching and other minor skin irritation. None of that was bad, but baking soda was nicer, so why not use that, we said.. bG Quote Link to comment Share on other sites More sharing options...
