Thanks Jeff, I too believe in the "Ain't broke, don't fix it" but I wanted to just check everything, sometimes a used tool has sat for a while and things like grease dries up and or bearings just need some TLC, so worth the time to check things out.
For the bath, you use about one tablespoon of baking soda (I used washing soda, a little stronger than baking soda) to one gallon of water. Warm the water up a touch, not as hot as coffee, maybe bath water hot, when you add the soda, makes this mix better and cook better too.
If you are filling a large tank then mix up the soda with one hot water gallon, all the soda at once, say you are mixing for 10 gallons, put ten tablespoons of soda into one gallon of hot water, mix well, then add that to the 9 other gallons of water, just easier is all.
Remember, the negative lead goes onto the piece you want cleaned and the positive lead goes onto the sacrificial piece of steel. One last thing, make sure the battery charger is unplugged with connecting or disconnecting the leads, one of the by products of this process is Oxygen which can explode if you had a high concentration of it and a spark......
Have fun, it works like magic, but do be careful!
