Water damage is likely to cause a mold problem, unless the books are promptly dried out. More often, a damp environment is the source of the problem.
Avoiding Mold in Books
The best way to deal with this problem is not to have it! Here are some tips to avoid mold in books:
- Do not store books in the basement, unless the basement is dry.
- Never place a cardbord box of books directly on a cement basement floor, no matter how dry the basement. Concrete wicks up moistuer and will likely cause damp books resulting in mold and mildew in the books.
- Use a dehumidifier to keep humidity low and mold in basement to a minimum.
- Line storage boxes with plastic (e.g. garbage bag) to keep out dampness. Take care that you do not make holes through the bags!
