Unfortunately, now get back to the time of year where the moisture in our car's creeps - even my relatively new car will not be spared them. BUT: these things here can create as real remedy. Since I did not know exactly how I had to "dose" I just got 2 piece placed in my car: 1x front and 1x rear. I feixe me every morning on the way to a car when I see the other shod car's and mine stands like aus'm egg peeled and I can drive off right away. While it is currently not yet winter, but I do not see why it should not work well in the winter as well. Super is that they are - if they have absorbed enough moisture - just place on the heating and whoosh, they are ready for use again. So I think the great and now knows what gets one or the other of me for Christmas ;-)
