wisedry Silica Gel Packets Car Dehumidifier Bag Reusable, 1kg [2 x 500 Gram] Microwave Fast Reactivated Desiccant Sachets Eliminates Foggy Damp Windscreen, Moisture Absorber for Car, Caravan, Van

Using these in my roof tent to keen moisture at bay and stopping it going mouldy.

They work well and easy to regenerate

I have 4 of these in my Discovery Mk2, Disco owners will know why. Overall they are doing a good job of reducing moisture build up from the various leaks that the car has developed over the decades. Currently I need to dry them out about once per month. Drying is the issue, the packs recommend 10 - 15 minutes a side to dry but in reality even in a fan oven, turning them over regularly it takes a few hours. There is a lot of volume in these packs and unlike the small 10 gram packs I use to keep my photo gear fungus free these take some drying.

We have a slightly leaky seal in the car door and the car gets misted up easily. These rechargeable dehumidifiers are keeping on top of the problem until we can get it sorted. Drying out takes longer than indicated, but it does work. We tend to bung them in the oven when it's been on for something else, so we're not wasting energy on drying them out. Think they're good!

I bought some of these to put inside the car to reduce the amount of condensation on the windows. They are a good size and fit neatly in the car door compartments. I like the fact they are reusable and are easy to recharge.

Do not seem to make much differenceAlso takes so long to dry outNot very convenient

Every morning last autumn and winter the inside of my car windows (Toyota Aygo) was running with condensation. So this year I thought I'd give these bags a try although I didn't really expect that much from them. I put one of the packs on the dashboard two months ago. Complete success, no condensation at all! I thought by now the pack must need recharging, so I brought it in and weighed it, and it did. Recharging it took 14 minutes in the microwave. Now the weather has turned a lot colder I guess I'll have to recharge it more frequently but that's no problem.So glad I found this, saves me spending ages wiping down the windows and then having to dry out the cloths and pads.

Difficult to judge if these are working the way they should, seem to draw in moisture but haven't had to dry out so 3 stars at this time.
