Isolate and Assess the Damage

If you discover mold on paper documents, immediately isolate the affected items to prevent further spread. Examine the extent of the mold growth and identify the type of document it has affected.

Safety Precautions

Before handling moldy documents, take appropriate safety precautions. Wear disposable gloves, a mask, and work in a well-ventilated area to avoid direct contact with mold spores.

Dry Brushing

Using a soft-bristled brush, gently remove loose mold spores and debris from the surface of the paper documents. Avoid applying excessive pressure to prevent smudging or tearing.

Sun Exposure

Mold thrives in humid environments, so expose the affected documents to direct sunlight for a few hours. Sunlight helps naturally inhibit mold growth and eliminate moisture.


For valuable documents or items with extensive mold damage, consider encapsulation. Place the affected documents in a clear, acid-free polyester sleeve or envelope to protect them from further contamination.


If you’re unable to attend to the moldy documents immediately, consider freezing them. Place the documents in a sealed plastic bag and store them in the freezer until you’re ready to clean them.

Cleaning Solutions

Create a gentle cleaning solution by mixing one part isopropyl alcohol with one part distilled water. Alternatively, you can use a mixture of one part white vinegar and three parts distilled water. Both solutions are effective in removing mold from paper.

Spot Cleaning

Dampen a soft cloth or cotton swab with the cleaning solution and gently spot clean the moldy areas on the paper documents. Work in small, circular motions to lift the mold without damaging the paper.


Allow the cleaned documents to air dry naturally in a well-ventilated area. Avoid using heat sources or direct sunlight for drying, as they may cause further damage.

Storing and Preventive Measures

Store the cleaned paper documents in a dry and cool environment, away from direct sunlight and humidity. Consider using archival-quality storage boxes or folders to protect them from future mold growth.


Successfully removing mold from paper documents requires delicate handling and appropriate cleaning techniques.
