What it fixes
One bag. Three winter problems.
Damp air in a parked car is what fogs your glass, soaks your mats and makes everything smell stale. PolarDry soaks it up.
Floor mats
Drier mats and footwells
Snow and rain off your shoes soaks into the mats. PolarDry pulls that moisture out of the air, so they dry out instead of staying damp.
Smell
No more musty smell
Damp trapped under the mats and in the boot is what makes a car smell stale. Less moisture means a fresher-smelling cabin.
Why PolarDry
It tells you when it's full.
The indicator on the front shows you exactly where it's at. When it turns pink, recharge it on a radiator or in the microwave and it's ready to go again. No refills, no replacements.
Blue = dry & working
Pink = recharge it

Questions
Good to know
How does it work?
PolarDry works on the inside of the car. It absorbs moisture from the air in the cabin, so less fog and frost forms on the inside of the glass.
How do I know when it needs recharging?
The indicator on the front is blue when it's dry and working, and turns pink when it's full of moisture. That's your cue to recharge it.
How do I recharge it?
Leave it on a warm radiator until the indicator turns blue again, or microwave it on a low setting in short bursts, letting it rest in between. Let it cool, then put it back in the car. Always follow the instructions printed on the bag.
How many do I need?
One bag is a good start for a small car. For bigger cars, or if you get a lot of condensation, use two: one at the front on the dashboard and one in the back or the boot.
Is it safe to keep in the car?
Yes. It's a sealed fabric bag of silica gel beads, with no liquid to leak and nothing to plug in. Keep it away from children and pets, and don't open the bag.
What if it doesn't work for me?
You're covered by our 30-day money-back guarantee. If you're not happy, get in touch within 30 days of delivery and we'll sort out a refund.

My van always smelt damp from wet boots and the dog. Had one sitting in the footwell for a fortnight and the mats are actually dry now and the smell’s gone. Didn’t expect much for the price, but it does what it says.

Honestly the school run was chaos with the windows steamed up and the kids moaning while we waited for the blowers. Now I can actually see out when we set off. Got the 2-pack, one in the front and one in the boot where the wet wellies go.
Leave for work at 6am and was spending 10 mins every morning wiping the inside of the windscreen with a sock 😂 Put one on the dash on Sunday and this week I’ve just got in and gone. Works like magic!
