[Alt-photo] Simple fix for clean borders on Pt Pd prints

I couldn't figure out why I was sometimes seeing some "dirt" in the white
borders around some platinum prints, looking almost like incomplete
clearing. I tried changing clearing routines, more acidic coating solution,
more acidic developer, different papers, and nothing seemed to work. Then I
filtered my Potassium Oxalate developer through a coffee filter, and that
solved the problem. I'm printing with sparkling white borders again. I
normally replenish my developer, but the sludge at the bottom of the bottle
was the culprit.
Happy New Year!
