    My developing and rinse trays for printing Pt/Pd prints are starting to look a bit on the grungy side. They are white trays but are now stained to approximately a Zone VI tone. What should I use to clean them and return them to their Zone IX brilliance?

    I use Potassium Oxalate as a developer.

    potassium ferricyanide has always worked well for me and since I already have it in the darkroom it's even better :smile:

    Mix a tablespoon into an 11x14 tray full or water and let sit overnight.

    I would recommend a scrub with baking soda. Followed by a complete rinse. Potassium Ferricyaninde will bleach somewhat but you will want to FIX it, and silver fixer is one of the BIG problem chemicals for staining your platinum prints.
