Step 1: Preparation
Brush off loose dirt and debris.
Step 2: Disassembly
Take out ballistic plates and inserts. These are not supposed to be submerged in water. If the inserts do get wet they will dry very slowly. The label sewn into the fabric indicates relevant cleaning information. Water, detergents, and other chemicals may damage the ballistic integrity of the material. The following instructions are for the non-ballistic outer shell only (shown on the right in the photo).
Step 3: Stain Removal
Spray deep stains with OxiClean stain remover and scrub with a bristle brush. Use a damp rag to wipe away dirt and oils. You may need to do this several times and repeat between steps as needed.
Step 4: Soaking
Soak the IOTV (body armor) shell in warm water with OxiClean for about an hour. Rinse and repeat as needed. You may need to continue scrubbing out dirt and oils during this step.
Step 5: Wash Cycle
Put your shell in a standard washing machine and add a scoop of detergent. Begin wash cycle.
Step 6: Drying
The most expedient drying method is a regular dryer. If this is not available or you want to avoid noise there are several other techniques.
1. Air dry in sunlight.
2. The Oven Method: For this you will need a clean oven. Put your shell in an oven preheated to 200 degrees Fahrenheit. Leave the oven door open 1/4 of the way. Observe your progress and remove when dry. Obviously there is fire/equipment damage risk using this technique. Be an intelligent adult. Do not leave your equipment unattended.
3. The Dry Sauna Method: This method works if you have access to a dry sauna. The advantage here is safety (unless you decide to sit in the sauna for three hours while your stuff drys). The disadvantage is security. Someone might steal your gear if you simply leave it drying in the sauna. Mitigate this risk by staying in the vicinity while your gear is drying. This method works according to the same principle as the oven. The heat will expedite the evaporation of moisture from your gear. (Thank you to 2LT Rolph for this tip)
