Here is another option that you guys can try, it's working pretty well so far for us.
Add 5 level t spoons of citric acid crystals and ONE T SPOON OF BAKING SODA, per gallon of water(distilled or rain water= works better).
Do not exceed amount.. if you need to add fluid, do not add fluid with
additive in it, the additive stays in the unit.
Excess additive is BAD overheating will occur; possible blown fuse, excessive corrosion and you could damage yourself if you don't handle it properly.
The generator wiring(plates) and excess additive will draw
excessive amps. you will need to add some water when you gas up.
Properly mixed units will draw less than 4 amps.
