## Description

Wisedry 4 x 500 Gram [4.6 lbs] Rechargeable Silica Gel Packets

Review: A month ago I never would've guessed the answer to my cars' inside window fogging problems could be as simple as a giant version of the same thing I've seen inside supplement bottles for my entire lifetime. Now I am a believer, and that's thanks to these WiseDry 500g desiccant packs! They worked for me exactly as advertised, including the recharge procedures. I purchased 8 packs and stuck 4 inside each of my problem children (vehicles, that is). The benefits played out over several days. I did need to wet vac out the pooled water in one of them to get maximum benefits from the packs. But the result over 4 weeks of constant usage is obvious--highly reduced condensation on the inside back and front windows of the two cars! In a wild, woolly, WET Pacific NW winter, that is an AMAZING result! I did discover the microwave is not a very efficient way to recharge all 8 even 2 at a time. It took these packs about 5 days to suck up enough moisture to go "full bloated" (650g weight or more) and following the instructions it would've taken a couple hours all told to get all back down to 505g +/- new weight. And that process pretty much required constant attention. I was actually concerned about the workout it gave my microwave, which isn't used to more than 20 or so minutes of use at a time. So I tried the oven method and was more satisfied using that for these packs. Keeping the oven temp below 300F it still took 6 1/2 hours to get all 8 packs down to recharged weight, but it was a completely hands off process. I don't have an easy way of measuring the energy use of my oven, but I wouldn't be surprised if cost was a wash due to the lower KW needed by a 240V appliance to provide same amount of heat as a 120V unit. That's physics so not gonna go there. Anyway, these packs fared well in the oven so that's likely how I'll generally recharge them. All told I'm giving them 5 stars and gonna keep them in mind for ALL my moisture-related problems henceforth. One note about oven recharging: I'm cheap so I order some less expensive versions of these 500g desiccant packs after seeing the results of the WD's--the white ones that look almost exactly like an overblown version of a vitamin pack, in every way, including seam sealing. Whereas the WD's are tubular construction with just very serious heat fused seams on the top and bottom, the cheaper packs have seams on all sides that did look less, shall I say, "sincere." I allowed them that slack since they were, in fact, cheaper and still claimed to be oven-chargeable. sWell don't you believe it!! Of the 6 of those packs I oven-recharged same as the WD's, 4 split their seams and spilled the beads! Would've been a much bigger mess had I not had a baking sheet below them to prevent direct heat from the oven elements. Oven temps were never about 300F but I believe should be kept to a limit of 250F for these packs. Then they seemed fine, but time of recharge would go up as much as several hours. I have yet to try that again--getting my courage back up...
Review: These 500g silica gel packs are great—they do exactly what they're supposed to do: keep your stuff dry and protected. But here's what they won't tell you—you can actually reactivate these packs over and over again instead of tossing them out. Just pop the silica pack in the oven at 250°F (120°C) for about 2 hours and it’ll be good as new. Let it cool completely, then seal it up or use it again. If your pack has a color indicator, you’ll see it turn back once it’s dry. I’ve done this multiple times and they keep working like a charm. Just don’t overheat them or use a microwave, and if they’re in plastic, check that the packaging can handle the heat—or pour the beads into a metal tray first. Simple, cheap, and effective.
