I've only worked on a Polimero once but I assume there are some
standard practices for most of the machines.
I flush the system at the end of the day or if the bath has become
quite opaque. I don't remove the brushes on my unit, just rub my hand
around on them to loosen the waste matter. Best not to spray wash them
or disturb the bristle pattern. Some machines close down on the
brushes at all times. If yours does, best not to close it when not in
use, but instead, use a piece of three-eight inch acetate to cover
over the bath area-let the brushes dry out first!!!. The cover also
allows the bath to heat up quickly and between use (thoughout the day)
will maintain the temperature of the bath somewhat.
I've seen some machines where the bath was not flushed on a regular
basis and they were full of organics (mould or algae or whatever)
living off the waste matter. And stunk. Since the waste itself
consists of organic matter (carbon molecules), best to flush it out of
there. Once things start growing they are hard to get rid of. I use a
cup of distilled vinegar in the bath but only to keep mineral deposits
down and to add a bit of acidity to the bath. Mecuric (sp?) acid can be occasionally run in the bath for cleaning (check with the manufacturer).
The Polimero URL is in the Links section here.
Keep the bath water about a quarter of an inch above the brushes.
Temperatures are somewhat dependent upon the plate (thickness,
manufactuer recommendations, etc). Get the technical sheets from the
