Per writers from Bountiful Gardens, simply placing desiccants in the sun will recharge them, so long as the local humidity is below 40 percent.
How do you dry out a desiccant pack?
You can do so by pouring the inactive silica gel beads in a thin layer on a baking sheet. You should then preheat the oven to 175 degrees Fahrenheit and bake the beads for 15 minutes. The heat in the oven will draw the moisture out of the desiccant pack, reactivating the drying agent.

Can You reuse desiccant packages?
Reusing Desiccant Packs: Silica gel is handy to have around to keep moisture at a minimum in packaging. It can be used to try to save wet cell phones, keep salt, sugar, and spices from clumping, and keep tools from rusting. Tackle boxes, camera cases, the possibilities are …
What is a desiccant pack?
Desiccant packs absorb moisture from the air to keep products dry. There are different types of bags, such as molecular sieve, montmorillonite clay, calcium chloride, and the typical silica gel.
How do you regenerate desiccant packets?
Yes, you can regenerate desiccant start by emptying the desiccant into a clean baking dish. Bake desiccant at 350º for two hours, or until silica gel particles turn dark blue, in a conventional oven (do not use a microwave).

Can you recharge desiccant?
Silica Gel can be restored to its original state by heating it in an oven to 120 °C (248 °F) for 1–2 hours. Once it is restored, it will return to its original color; either orange or blue depending on its type. Silica Gel gets saturated with moisture rather quickly when there is a high level of humidity in the air.
Can you recharge silica gel in the microwave?
It has come to my attention that people aren't aware that you can microwave your desiccant to remove the moisture from it. I put them in for a minute at a time, then flip them, then do another minute. Be careful when flipping them as it will be hot. Thankfully you can grab the edge of the packet and be fine.
Do desiccant packs expire?
The silica gel packets – also referred to as desiccant packets or dry packets – do not expire. They are made from a material that will not expire or go bad. But as the silica gel packets are exposed to air and moisture, they will become less effective until eventually, they have totally lost their usefulness.
Can moisture absorbers be reused?
Reactivate and Reuse! After the silica gel absorbs moisture (up to 40 percent of its own weight), it loses its effectiveness. But there is a silver lining to this rain cloud: The beads can be reactivated and reused repeatedly.
How do I know if my desiccant is good?
If it never reaches the desired dew point or doesn't hold it for long, then it's probably time to change the desiccant. Pull the desiccant beads out and squish them between your fingers. If they are very brittle and crumble upon doing so, they're bad and need to be replaced.
Can desiccant bags be reused?
Recharging Desiccants for Reuse Per writers from Bountiful Gardens, simply placing desiccants in the sun will recharge them, so long as the local humidity is below 40 percent.
How do you remove moisture from desiccant?
According to Dry & Dry producer of silica gel, you should dry for 0.5 to 2 hours at 200 to 250 F in a conventional oven. In silica gel, the physically adsorbed water can easily be removed when kept in an air oven at temperature around 150 degree centigrade temperature for 2-3 hours.
Can silica gel be regenerated?
Silica gels can be regenerated heating up to 180°F, whereas molecular sieves can be regenerated by heating them to up to ~550°C, it will release the trapped water. This process is called regenerating the desiccant.
What temperature should silica gel be used for reuse?
Oven temperatures to prepare silica gel for reuse are primarily limited to less than 300 degrees. Above that temperature, the silica’s absorbent properties become damaged. The other limiting factor is a packet's material limitations. Plastic packets often fare better at 175 degrees, though this will take longer to effectively recharge the silica gel desiccant.
Can you microwave a silica gel?
Sta-Dri, which manufactures the silica gel desiccant packs, warns against using a microwave, and, in fact, makes this warning prominent, although it does not explain the reasoning. Ted Pella, however, states that you can use a microwave but just be sure that it is not stronger than 900 watts.
Step 1: Wow!
I got this big honker at work. I work in a hospital laboratory and these are used in a part of an analyzer to keep the reagents at a certain humidity. After a while the desiccant absorbs too capacity and can't keep the humidity stable and the machine requests new ones.
Step 2: Drive That Moisture Out
You could probably do this in a microwave for smaller packets. Maybe a few 15 to 30 second bursts. I had nearly 2 pounds of these things so I decided to put them in a low oven (250F) and let them go for an hour and a half.
How long to microwave silica gel?
If it is not dry, stir with a spoon and place back into the microwave for an additional three to five minutes.
Can you throw silica gel out?
Overtime, however, the silica gel can lose its moisture-removing power and become ineffective. When this occurs, don't throw the silica gel out: recharge or dry it with heat so you can continue to use it. Advertisement.
