RE: Mike Ware's POP Pt./Pd. Pt
Sandy, That is exactly what I experience but I am a bit worried what EDTA does to the metal that forms the image when stain is gone but clearing of the paper incomplete.

Pt Witho, I would add that there is almost no need for clearing after development in Disodium EDTA. The recommended time of development is ten minutes, but after only five minutes all of the stain is gone. This appears to be a much more effective method of development in terms of clearing than development in oxalate.
