Keeping Military Items in Good Condition
That leather holster, the wool uniform, the paper documents – they all have enemies. Humidity, temperature swings, light exposure, and pests will damage your collection if you ignore basic preservation principles.
Temperature and Humidity Control
The ideal range for most military collectibles sits between 65 and 70 degrees Fahrenheit with relative humidity around 40 to 50 percent. More important than hitting exact numbers is maintaining consistency. A basement that swings from 50 to 80 percent humidity seasonally causes more damage than a room steady at 55 percent.
Dehumidifiers and humidifiers with hygrometers help you monitor and control conditions. Wireless humidity monitors like those from Govee or AcuRite let you check multiple storage areas from your phone.
Storage Materials Matter
Cardboard boxes and plastic bags from the store are not archival materials. Acid-free tissue paper, unbleached muslin, and archival boxes from suppliers like Gaylord Archival protect textiles and paper. Silica gel packets inside sealed containers help regulate moisture for metal items.
Never store items in direct contact with wood or cardboard. The acids in these materials transfer to your collectibles over time.
Leather Care
Leather holsters, belts, boots, and equipment need periodic conditioning to prevent cracking. Renaissance Wax or Pecard Leather Dressing work well for most military leather. Apply sparingly – too much attracts dust and can darken materials permanently.
Metal Preservation
Light gun oil protects metal parts on weapons. Renaissance Wax works for blued steel, brass, and other finished metals. Avoid touching bare metal with bare hands – skin oils cause corrosion. Cotton gloves when handling, always.
Document and Paper Storage
Flat storage in acid-free folders beats rolled or folded documents every time. Mylar sleeves protect individual items while allowing viewing. Store vertically in archival boxes, never loose in drawers where handling damage accumulates.
