Occasionally black specks may appear on the surface of a platinum/palladium
print. Several years ago Michael Mutmansky <sp?> along with Dana Sullivan
described a method of bleaching these spots to paper white using tiny
amounts of hydrogen peroxide mixed carefully with very small amounts of
hydrochloric acid which is then applied to the paper gingerly and in small
amounts with a high quality spotting brush sans metal ferrule.
You can search in the old alt list archives or e-mail Dana Sullivan at
Bostick & Sullivan and inquire about their methodology.

Subject: [alt-photo] Removing marks on pt/pd prints
Hello All, I've been asked by to do research regarding removing marks from
platinum prints. I don't quite understand the nature of the marks as this
wasn't made clear to me. Something was mentioned about using peroxide. Could
anybody expand on this for me please?
