Game changer
No more scraping the inside of my windshield at 6am. Wish I'd bought it last winter.

FrostFix sits on your dash and pulls the damp out of your car overnight, so the glass doesn't fog or frost up on the inside.

What it fixes
One small bag. Three damp-car problems.
Clear morning windows
With less moisture in the cabin, the glass doesn't fog or frost over on the inside.
Dry floor mats
Wet mats dry out while the car sits parked, instead of staying soggy all week.
No musty smell
Drier cabin air means that stale, damp smell never gets a chance to settle in.
Good to know
Questions, answered
Does it melt ice on the outside of the windshield?
No. FrostFix works on the air inside the car. It keeps the glass from fogging or frosting on the inside. It does not melt outside ice, clear snow or heat the car, so you will still need a scraper for the outside.
How do I know when it needs recharging?
Look at the circle on the front of the bag. Blue means it's dry and working. When the blue turns pink, the bag is full and needs a recharge.
How do I recharge it?
The quickest way is the microwave. Wrap the bag in a paper towel, heat it for about 6 minutes at 600 W, and let it cool. You can also leave it on a radiator for 1 to 2 days, or put it in a low oven with the door slightly open.
Is it safe to keep in the car?
Yes. It's a fabric pouch of silica gel with no chemicals, no batteries and no liquid. There is nothing to spill, leak or plug in.
How many do I need?
One bag on the dash handles the windshield. We recommend two: the second goes in the back for the rear window and floor mats. The 4 bag pack covers two cars.
Wake up to clear windows.
Put FrostFix on your dash tonight and see the difference tomorrow morning.
