The short answer
Assess the Damage First
Begin by separating the items. Dry materials with light surface mold are often easier to save than wet, heavily stained ones. If the pages are stuck together or the paper is turning to pulp, you may only be able to salvage a few pages or the cover.
Wear a mask and gloves while handling moldy materials to protect your lungs and skin. Work in a well-ventilated area, preferably outdoors or with windows open. If the mold is extensive or you feel unwell, see a doctor and consider calling in a professional who has the right equipment.
Freeze to Stop the Spread
For wet books and papers, freezing is one of the safest first steps. Place each item in a zip-top bag, remove as much air as possible, and put it in the freezer. Freezing halts mold growth and buys you time to decide how to proceed.
Once frozen, you can thaw items slowly in the refrigerator and then air-dry them. This approach works well for paper that is not already crumbling. If you have many items, a local water damage pro can help with freeze-drying services that preserve the structure of the paper.
- Separate wet items from dry ones immediately
- Freeze or dry within 48 hours if possible
- Use fans and dehumidifiers to speed air drying
- Handle pages gently to avoid tearing
- Do not use heat, which can set stains
Dry Books and Papers Slowly
Air drying is the most common method for slightly damp or moldy books. Stand books upright with a fan blowing across them, but not directly on the pages. Interleave paper towels between pages every 20 to 30 pages, replacing them as they become damp.
For loose papers, spread them flat on a clean, dry surface. Weigh down edges with a light object to prevent curling. Drying can take several days; patience is key. In humid climates, drying may take longer, so consider using a dehumidifier in the room to speed the process.
Clean Surface Mold Safely
Once the material is completely dry, you can remove light surface mold with a soft brush or a dry sponge. Work outdoors or in a ventilated space, and wear a mask. Brush gently from the center of the page outward to avoid tearing.
For stubborn spots, a cloth slightly dampened with isopropyl alcohol can help, but test it on an inconspicuous area first. Alcohol evaporates quickly and may reduce staining. Never use bleach or water on moldy paper, as it can cause further damage.
- Use a soft brush or dry sponge
- Work outdoors or with windows open
- Test any cleaning solution on a small area
- Avoid water and bleach
- Let items dry fully before returning them to shelves
Know When to Call a Pro
If the books or papers are irreplaceable, such as family photos, legal documents, or rare books, a professional conservator is the safest choice. They have the tools and knowledge to dry, clean, and repair items without causing further harm.
For large quantities of moldy paper, a local water damage pro can provide structural drying and dehumidification services to help stabilize the environment in your home. This prevents mold from spreading to other belongings. Policies vary, and your insurer decides what is covered, so check your policy if you plan to file a claim.

Can I save a book that is completely soaked?
It depends on the paper quality and how soon you act. Freeze it first, then thaw and dry slowly. If the pages are stuck or the book is heavily stained, you may only save parts of it.
Is it safe to keep moldy books in my home?
No, mold can spread to other items and affect your health. Remove them from your living space and isolate them in a dry, ventilated area until you can clean or discard them.
Should I throw away all moldy papers?
Not necessarily. Many papers can be saved if you act quickly. However, if the paper is crumbling, has a strong musty odor, or the mold is deep, you may need to discard it for health reasons.
