I have a few posters with a couple of visible fingerprints on them. Does not appear to be dirt, just ordinary fingerprints from a slightly sweaty hand.
I am certain that a professional restorer could remove these during restoration, but is there any less intrusive way to do this myself? Paper-wise, we are talking both a modern glossy poster, an older poster printed on some more matte paper and a movie program.
The fingerprints are only visible in black areas, like a black background or a photo in the movie program.
I saw someone using something called Absorene for removing surface dirt from a poster. Would that maybe do the trick?
