I fogged up the interior of my car in cold weather this winter. Now whenever the car is left over night there is frost (think enough that you can't see through it) on the interior of the windows, mainly the windshield and it ends up taking a while to de-frost in the morning. It's just a pain because I'm really not one to leave my car running for 15 minutes to de-frost. Once it's de-frosted it's usually gone for the day but when temperature's hit extreme colds overnight the frost returns by morning. Is there any method to get rid of the interior frost that you guys would recommend?
