Arentz teaches the students to rinse the brush in tap (fitered), then into distilled for a quick rinse and a shake until moist, then hang. Prior to coating the next print, its into the distilled and a shake until damp (actually a flick).
Not much chemistry in the brush after coating.
Anyway, a small price to pay for consistency in coating – at least you know that you don’t have Ferrous compounds in the brush.
Bottom line – choose a method and be consistent. Whether its wrapping the brush between coatings or wash/hang.

Subject: what to do with brush between pt/pd coating?
It occurred to me recently to ask this seemingly simple question...please excuse my apparent ignorance.
If I am coating several 8x10 sheets in one coating session, what should I do with the brush between coatings?
Surely, I shouldn't have to clean it between each one and lose precious solution that is soaked in the bristles...
