Hi Roger,
I do not clean my electrodes when making a batch, I do use constant stirring.
Batch sizes vary from 12oz to 56oz, current at the end of the batch is about
1.5ma. 30vdc power supply that gets limited down to about 12-15vdc at the end.
Starting current usually about 0.23-0.38ma depending on the size of the silver
leads I use.  I only wipe the electrodes off at the end of the batch, no fuzzy
hair, just a dark coating that comes off rather easily.  Stirring is gentle but
continuous to prevent a high concentration between the silver electrodes.  Seems
to work very well.
