Photo Forum / Film Photography / Darkroom / August 2004Mildewy mount board
This is not, strictly speaking, a darkroom question, but I'm not sure where else to turn for help. I mount my prints on 4-ply, archival board, and own some other photographers' prints mounted the same way. Winters where I live are humid, and some of the older boards are starting to display patches of what I presume is mildew (light brown) over their entire surfaces. Some seems to wipe off with relative ease, but since the board is porous it's hard to totally remove the stains. Is there any way to safely clean the mount boards and save the prints? Thanks for any help! EricM > This is not, strictly speaking, a darkroom question, but I'm not sure where > else to turn for help.

Thanks for any help! > EricM Do a google search on "foxing" of paper or books and see what treatments they suggest. You might also trim the mount at the edge of the print and remount the trimmed print to a new mat. You could also try foamcore in the future. Best bet is to store you prints with plenty of air circulation and a dehumidifier running.

Mat boards are tolerant to light applications of solutions applied with a wrung-out sponge. The dampness raises the "tooth" of the mat board a bit, but I've never damaged one by doing it.

Perhaps one of these (or similar) products would absorb enough moisture from the mountboard that the mildew could be easily brushed off.

Thanks for any help! > EricM The best thing is to get the prints off the boards and toss the boards. Getting rid of fungus is quite difficult. I suggest going over the material at the Conservation On Line site at http://palimpsest.stanford.edu There is guite a bit on fungus and how to get rid of it there.
