Leonard from California emailed with this question “I have several archival 3-ring binders that are getting brown spots on the inside covers. I store them next to non-archival photo albums which are in the process of restoration. Can mildew migrate to these new binders? Should I have to wipe out the cabinets with bleach? Are these new archival binders ruined?
Leonard has brought up a great preservation question. He is experiencing brown spots on his 3-ring binders and is concerned about the spread of these spots and rightly so. The “brown spots” that Leonard describes is actually what we call in the archives world “foxing”. Foxing is defined as “Small, irregular, brown blemishes on paper which is consistent with mold or mildew”. (Society of American Archivist Glossary of Terms http://www2.archivists.org/glossary)
These types of brown spots or foxing can infect genealogical documents, photos books or binders. Most, if not all, foxing is caused by mold growth. This means that there is moisture present, high humidity and no ventilation in the area where the genealogical records are being stored. Always remember: Heat + Moisture = Mold. Fluctuations in temperature and humidity do the most damage to genealogical documents and photos. Ideally, genealogists should store their genealogical records collections in an area where the temperature is maintained at below 70 degrees and humidity below 50. The best place to store genealogical records is in an interior closet. Never store records in an attic, basement, laundry room, garage or utility room. Do not store records near a heat source such as a radiator or fireplace. All genealogists are encouraged to invest in a temperature and humidity meter to be placed with your record collections so these levels can be measured and adjusted if needed.
Leonard asks if these spots can migrate to the other binders and the answer is yes. Mold can grow in these conditions and will continue to grow and migrate to the other binders in Leonard’s collection. The binders must be cleaned properly to remove the mold and better storage needs to be implemented to deter further mold from growing.
This use of bleach is not recommended. Any chemicals that are used on genealogical records and binders could cause damage by breaking down the paper and could eventually disintegrate whatever paper the chemicals have come in contact. Also, do not use any detergents or mold and mildew cleaners that are typically used in the home. These contain chemicals that can cause damage.
The easiest and best option for Leonard and anyone else with this problem is to take a slightly damp, clean cloth and wipe down the binders. This should remove most of the brown spots. Take a separate clean, dry cloth and wipe down the binders to remove any excess moisture. Another option is to take the binders outside on a very warm sunny day and let them sit in the sun for thirty minutes to an hour. The heat from the sun should kill off the mold spores and the ventilation and fresh air outside will help as well. If this procedure does not remove all the brown spots and the damage is more extensive, my professional advice is to call your local or state archives and talk to the in-house conservator for additional help.
Genealogical records need to be cared for and preserved in the best possible conditions or they will deteriorate and be destroyed. As genealogists, we have the care of our genealogical records and knowing how to preserve and care for them should be our top priority.
