It is hardly worth the effort, the amount might be worth a hundredth of
a penny. If you want to minimize the formation of this coating, then
wash it off immediately with distilled water. If you want to remove it,
then put it in H2O2.

Some silver will plate out on the negative electrode. Using a
silver negative electrode allows you to recover the plated out
silver for use.

Correct me if I am wrong, but absolutely NOTHING physically comes
off of the negative terminal during production, right? The only
thing that comes off would be electrons reacting with water
molecules or incoming silver ions or a few amount of contaminant
cations. I'm wondering if the ideal gen has a lot of surface area
on cathode also. If so, copper would be preferable so you don't
pay for all that extra silver.
Hey, could that also make a gen that doubles as a colloidal copper
setup? What do people use colloidal copper for anyway?

The cathode (in this case the negative terminal) can be copper

The anode (in this case the positive terminal) must be silver.
You can see I don't agree with cking, as usual...
