wisedry50 Gram [10 Packs] Silica Gel Packets Microwave Fast Reactivate Desiccan Packs with Indicating Beads

I use these to absorb excess humidity in my guitar cases. Been using/reusing them through two summers now. I track the humidity level with a hydrometer in each guitar case. They definitely work.

I recently purchased a pair of matrix LED headlights to upgrade the xenon headlights in my Porsche Cayenne GTS. A few weeks after installation, I noticed a build-up of condensation in one of the headlights. I saw a video online that suggested the condensation could be removed by installing several silica packets inside the headlight housing. I removed one of the covers from the back of the headlight housing and placed 2 of these silica gel packets inside the headlight and sealed it back up. The next day the condensation was gone and a week later, it has not returned. I'm sure these packets have many uses, and this is just one example. Highly recommended.

I really like these reusable desscciant packs. They work great for 3d printer filament storage.

I bought silica gel packs for protecting electrical/computer equipment from high humidity here in Arkansas and because they are reusable. They are reusable , but they don't last all that long, maybe 8-10 times before the packets start breaking down

I have an older stronger 1200w microwave. for 50gs it says 8mins total, 4mins each side, for 4x 50g bags for a 1000w microwave. I did this in safer increments reading the alarmist melty firey smoky reviews of avoid microwave.I did it at first for 10 seconds, then 15 seconds, then 30 seconds, then 45 seconds and gradually WEIGHING these and monitoring for my first 4x 50g batch.Then I increase to 1min at 50% power, and ran it a couple minutes like that and measured weight.I think the instructions overall add up if you have 62-66g instead of 50 to start with, but I would be careful and try to check halfway and then quarter way in to avoid melts and smokes and not do 2 hours in an oven either.It's simply math, you will get a natural feel for it with your specific microwave. I did 2nd batch and ran 2mins one side 100% power and 2mins 100% another side, and separate minute longs for each side and this time I actually ended up doing a total of more than 8mins to get them to 50-51gr each.Consider how accurate your scale is, some are accurate down to 1-2gr, and this might mean you are better off safely stopping at 51-52 instead of trying to go to 50 exact in a perfectionist way. it can still absorb 14-15gr of water, just 1-2gr short.Remember, the friggin crystals inside get REALLY hot at 3-4min long runs and there is EVEN HOTTER inner crystals and trapped water vapor that can absolutely burn ya if you are not cautious. and so these crystals retain their heat for a while and can lose out your last 1-2grs this way.Also consider the ambient humidity of your particular room or area, if you have a moist air or wet climate, of course letting this stuff sit in the open can cause them not only not get dryer but to slowly absorb more and more moisture from the air.After recharge, reseal all in a well built zip lock or airtight mason jar or container.There, and READ THE DARN DETAILS, if you you use what nature gave ya, your eyes, your internet and your brains and follow the instructions and your gut, there will be no melting and no smoking.Remember the part where it says after a series of drying cycles the yellow beads may no longer be color reactive but the weight measurements and stopping the microwaving periodically to control progress is the key, yes, this means you will sit or stand by your microwave and scale for a while for drying a bunch of packages, but this means you have better control over losing stuff that are not that cheap to buy either.I might try an oven later, I just did not feel like waiting 90+mins as I needed a few right away and had saved all my dark colored ones over months in another zip lock.

These are very durable and will last through many recharging cycles. The color change is definitive so you know when they are working and when they need a recharge. I've bought multiple packs of these using many different locations.

I keep a couple of these in my forearm and accessory cases and they work great, microwave when the beads turn dark and let them sit in the sun to finish evaporating and boom, good to go for another year or two (my cases are waterproof and don't really come out that often, so mileage may vary)I've used these to further make bone-dry fruits from my dehydrator and it works great to keep things fresh in long term storage. I put everything food related In its own Ziploc and a few of these in a gallon Ziploc with the smaller baggies and things stay crunchy on the rainiest of hikes :)Recommend letting them cool or picking up with tongs when pulling from the microwave, as they will be steaming! Definitely speaks to how much water they remove from ambient air!

I have bought at least 3 packs of these and will continue to do so. I use these for long term storage of food in airtight containers. If I feel the need I can pop the container open periodically and "re-charge" these by putting them in the microwave per the included instructions, then seal the package back up.Cheap peace of mind for long term storage.
