wisedry 20 Gram [12PACKS] Rechargeable Silica Gel Desiccant Packets Desiccant Bags Orange to Green indicating for Air Dryer Food Grade

Had condensation in one of my car headlights so thought I would try one of these and omg! ... after a few days the headlight is dry!! Wow I'm very impressed. You can dry these out in the microwave and reuse them too!

A little smaller than expected - as the size takes in to account the seals around the bags.Work well.Using in theatre Mic belts to absorb sweat before it affects the microphones.

This is just what I wanted. Large bag with water absorbing chemical and colour change to indicate when it needs to be dried out.

used to keep binoculars dry in a sealed plastic box, aslo to stop incense charcoal disk from adsorbing moisture

Exactly as described, great for removing moisture

I have lots of books temporarily stored upstairs whilst I'm sorting out the living room. When moving them into plastic storage boxes I noticed some of them smelt a bit musty, likely due to condensation. So I got this silica gel desiccant to help out. I've put a couple of sachets into each box and hopefully that will do the trick. As these sachets can be recharged I'll be able to reuse them if they do absorb a lot of moisture.I've often used silica gel before with cameras and binoculars etc and it does work as long as the article is kept in a closed bag or container. As mentioned this product is reusable so should last a good while.

These work as intended however on my first attempt at “recharging” and following the instructions to the letter one of the packs burst along the seam and is now unusable.

These are great as they are small enough to squidge into small dried herb containers and there are so many of them that as soon as the orange disappears you can replace with a new one. I use my air fryer to dehydrate used ones again and this works fine although takes much longer than I would have liked. It is also worth using a micro scale as often, when dehydrating, the weight has almost returned to its dehydrated weight but the crystals have not yet turned orange. At this point I use them again, rather than waste time and power trying to get them any drier. I store dehydrated lions mane mushrooms which cost a fortune so keeping them cracker dry is really important to me.
