Reversing polarity of the electrodes while making CS is an effective and
widely used method of decreasing buildup of silver and oxides of silver
on the electrodes. I have made thousands of gallons of CS, and I
reverse every minute, on a two minute cycle. Reversing eliminates the
dark oxides because the electrode which forms the oxide is exposed to
monoatomic hydrogen during the next half cycle, and the hydrogen
immediately reacts with the oxide reducing the silver oxide to silver.
Also any silver powder that accumulates on an electrode, either by
reduction of silver oxide, or by deposition of silver from the solution,
goes back out on the next half cycle as well. The result is electrodes
which stay amazingly clean and never need to be cleaned. I can
typically make several thousand gallons of CS on a set of electrodes and
have never ever had to clean them.
Also I have never witnessed any silver oxide coming loose due to
polarity switching. If any were to come loose it would be from the
stirring of the water, not a polarity switch.

The idea of reversing polarity during the manufacturing process is a
very bad idea and obvious design flaw. Far better to select one
electrode, and make a mark at the top with a pair of pliers, then
simply connect it to positive one run , then negative the next,
keeping note of dates you use the marked electrode with neg or pos
current.
The reason for this is that you will accrue a large amount of dark
oxides which should not be disturbed during manufacturing. If they get
into the sol (colloid) then the ions coming of the electrode will then
stick to those chunks and your sol will bottom out much quicker, the
particles also being less therapeutically beneficial as they will be
getting so large to the point where they will just not be able to pass
inside cell tissue and kill pathogens, also creating more possibility
of argyria skin discolouration, though that can be lessened or even
removed with selenium supplementation to chelate it from the skin I
read. The regular changing of polarity will just push a load of muck
into the distilled water and act as a magnet for the smaller groups of
ions to stick to.

I am considering using this to make colloidal silver. I like the
idea of reversing polarity because it will slow down a build_up of
CS near one electrode and both electrodes (hopefully) wear evenly.
Also I have one of these around and it will save a bit for the
time being :-)
Are there any "cons (& pros)" to this notion. I would appreciate
your thoughts on this. Thank you.
