Subject: electrocleaning

Has anyone tried electrocleaning PCB in say 5% sodium hydroxide, sodium
carbonate or caustic dishwashing detergent ? Its basically two steel
sheets on each side of the PCB. The PCB becomes -ve and steel is +ve. I
haven't tried it to strip toner, but I've seen this method remove old
paint. The disadvantage is you need setup a tank and power supply.
Current density should be at least 20 mA/cm^2
