How to remove crud from negative once it's dried

[Rev. Sidney Flack]

I have some important TMX negative that, through my own negligence, have an alar ming amount of crud on them. The most embarrassing part is that I saw the crud on them when I removed them from photoflo, noted that it must have come from the bottome of the bottle foam I'd just emptied into the bath, and then hung them u p to dry! I've tried resoaking them in photoflo and have used a microfiber clot h on the base side where much of it resides. But I've had little or no success. Any suggestions?

Try giving the film another extended wash...this will be more difficult if you have already cot your negatives. A strong wash with agitation will generaly remove most of the crud...then re-photoflo as normal.

If the extended wash doesn't work, you might try a solvent such as PEC 12. It does a wonderful job of removing ink from prints. The bottle comes with a finger pump spray head and I'd hope it might let the crud run off. If not, you might have to use a lens chamois or cloth besides.
