Advice on cleaning editing marks on silver gelatin photos

[thecatspajamas]

Distilled water and Q-tips. Most editor's paint is water soluble, and as long as you don't wet the gelatin base to the point that it gets "gummy" you should be okay. Better to remove some, let it dry, then remove some more than to push your luck with doing it all in one go. Q-tips work well for delivering the water, and you can kind of twirl them slowly to lift up the paint once it's wet. Don't skimp on the Q-tips, and don't be afraid to take your time doing it in multiple passes one small area at a time.

Also, if this is your first attempt, pick up a couple of crappy photos with similar paint on them and practice. There's no need to get your feet wet with a nice photo as your first attempt.
