Can’t buy it, make it.
https://www.frfrogspad.com/homemade.htmJust for those of you with curious minds, the Outers CopOut Plus solution contain approximately 0.6 percent cupric acetate and 2.5 percent ammonium acetate (3.62 grams/ liter of copper acetate and 38.5 grams/liter of ammonium acetate) in distilled/deionized water. The LeadOut Plus contains approximately 2 percent lead acetate and 5 percent ammonium acetate (6.50 grams/liter of lead acetate and 38.5 grams/liter of ammonium acetate ) in distilled/deionized water. A good basic solution for either would be
Copper Solution
562.3 grains Ammonium Acetate
51.3 grains Copper Acetate or 58.3 grains Cupric Acetate Monohydrate
Add distilled (or high megohm deionized) water to make 1 Qt.
Lead Solution
562.3 grains Ammonium Acetate
95.0 grains Lead Acetate or 110.8 grains of Lead Acetate Trihydrate
Add distilled (or high megohm deionized) water to make 1 Qt.
Note that since the Outers FoulOut unit limits the voltage and current in the electrolysis process and runs at about .3 volts (3/10 volt)-- at typically a max of about 20 milliamps.
