 Greetings friends! This is Survival Doc. Today I'm going to do a review of the dry top desiccants. You can order these on their webpage drytopproducts.com. When I received my products, they were this green color indicating that they needed to be recharged when they're ready to go. They're this orange color. So I simply recharged them in my oven according to the instructions. These are food grade. You can't eat them of course, but they are safe to put in with your food. So if you want to put these in with your freeze-dried foods for long-term food storage, you can do that safely. Also the plastic is BPA free. I'm putting these two larger dry top canisters in my gun cabinet to absorb moisture before it can do damage to my firearms. And I'm going to put the smaller ones in my M-O can. They come with this nice little holder here with a pillow stick it on the back. So if you want you can stick this somewhere and put your dry top in there like this. And then all you have to do is just keep an eye on it and when this orange color turns dark or green color, then you just put it in the oven like the instructions say and recharge it. It turns orange again and it's ready to go again. According to the directions that came with them, to reactivate when silica crystals turn from orange to green, place capsule on a paper towel in the microwave for 30 seconds. Repeat for an additional 30 seconds if necessary to return the crystals to the original color. For conventional ovens, heat for 45 minutes at 250 degrees Fahrenheit then allow to cool. And this is how a recharged mine in a conventional oven with the heat on for 250 degrees Fahrenheit for 45 minutes and the crystals recharge turning from green to orange just like they're supposed to do. I put one of these smaller dry top canisters in each of my M-O cans. I give these dry top desiccant canisters a thumbs up. This is survival doc reminding you be prepared or be prepared to be fleeced and don't forget to keep your powder dry.
