Cars are a great means of transportation, but they come with their share of annoyances, like parking tickets, insurance bills—and frosty or fogged-up windows. During the winter, drivers in cold climates waste precious morning minutes just waiting for the car to heat up and defrost. The defrost button is a great place to start when reclaiming use of your windshield, but everyone has tricks that they think work the best. Some people blast the heat, while others try opening the window. So what tactic is best when you're trying to get out of the driveway in record time?

YouTuber Mark Rober tested out 10 different methods to see what worked the best. According to Rober, the trick is a combination of things: Put the heater on full-blast, turn on the A/C, turn off the in-car air circulation, and crack your windows. If that fails, you can also put some kitty litter in a sock and place it near the windshield.
