The good news is that you can reuse these crystals as many times as you like, and the procedure is quite simple. All you need is an oven, an oven-safe dish, maybe some aluminium foil to hold the crystals, and you’re ready to recharge Silica Gel. Here are the steps:
Spread the crystals across the bottom of a bake-safe oven dish (you can use aluminium foil if you prefer to keep it off the dish itself). Spread them evenly and less than an inch deep in the dish.
Place the dish in an oven and heat it to 120° C (250° F) for 1–2 hours until they start changing colour. If you want to avoid the risk of making your Silica Gel inactive, you could use a lower temperature and leave the Silica Gel in for a longer period of time.
CAUTION: Do not heat Silica Gel to more than 180° C because it will lose its ability to absorb moisture.
The Silica Gel crystals will release the trapped water from within them, and revert to their original blue or orange colour. Once the colour changes fully, the Silica Gel is recharged and restored to its original capacity.
Note that the chemical that actually indicates the there is water in the silica gel crystals is a little more sensitive, and will most likely turn blue before the Silica Gel is fully refreshed. This is why we suggest leaving the crystals in the oven for a while longer, after the crystals turn blue / orange.
Allow the crystals to cool down before you touch them, and then restore them to their perforated containers in your camera bag or cabinet.
Store them in an airtight container so that they don’t absorb moisture from the atmosphere when they are not in use.
Use an airtight storage container for your camera equipment so that humidity doesn’t come in from outside and saturate the Silica Gel crystals. Remember to recharge your crystals often enough, and you should be fine.
