Description
Description
is a reusable silica gel dehumidifier bag with a built-in colour indicator. Put it on the dashboard, under a seat, in the back or in the trunk: while the car is parked, it pulls the damp out of the air around it. Clear glass on the inside in the morning, dry floor mats, a dry trunk, no musty smell, and an interior that gives mould nothing to grow on.
- Keeps the whole car dry: windows, floor mats and trunk, while the car is parked
- Stops the damp, musty smell at the source and keeps mould from taking hold
- Built-in indicator: blue = dry and working, pink = time to recharge
- Reusable for years: recharge in the microwave or on a radiator
- Light and compact: fits on the dashboard, in a door pocket, under a seat or in the trunk
- No chemicals, no batteries, no liquid, nothing to refill or spill
- Works in cars, vans, caravans and boats, and at home (wardrobes, basements, gym bags)
- Every bundle includes a non-slip dash mat so the bag stays where you put it
How to use
How to use
1. Place it. Put the bag on the non-slip mat on the dashboard. Door pockets, the rear shelf or under the seats work too.
2. Leave it. It works while the car is parked, overnight and during the day. No plug, no setup.
3. Check the indicator. Blue means it is dry and absorbing. When the window turns pink, it is saturated and needs a recharge.
Tip: for a larger cabin, a van or a car that gets very damp (wet shoes, dog, snow on the mats), use two or more bags, one on the dashboard and one in the back.
Recharging
Recharging
When the indicator turns pink, wrap the bag in a paper towel and warm it in the microwave for about 6 minutes at 600 W. Let it cool, and when the indicator is blue again it is ready to go back in the car.
No microwave? Leave it on a radiator for 1–2 days, or in a warm oven on the lowest setting with the door ajar. Repeat as often as needed: one bag lasts for years.

Questions
Does it melt ice on the outside of the windshield?
Does it melt ice on the outside of the windshield?
No. works on the inside of the car. It absorbs moisture from the cabin air so less fog and frost forms on the inside of the glass. It does not melt outside ice, remove snow or heat the car.

How many do I need?
How many do I need?
One bag on the dashboard is enough to keep all the windows clear. If you also want dry floor mats and a dry trunk, we recommend two bags: one on the dashboard and one in the back seat area or in the trunk.
