I have a lot of old family B&W film negatives that I want to invert, but many of them, after inverting, show up like these. What can I do to clean them up and remove the lines vertical and horizontal? I have used lens wipe and isopropol alcohol on a few which has cleaned up smudges, fingerprints, etc. but the striations? are still there.
It looks like a negative developed in a home darkroom with the person using a dirty squegee or damp sponge to try to wipe water spots off the damp emulsion.
