I would throw them all away. Even if you somehow manage to clean them, you will never be sure that there is no mold left there. And that's the kind of caca you don't want to keep around.
Preferred method for removing mold & mildew from album covers
I just scored some albums from a garage sale that have quite a bit of mold and mildew on the covers . The records themselves are in pretty decent shape . I know how to clean the records but am not sure about the covers . I have them airing out right now .
Can anyone help ?
Thank You
