(KSNF/KODE) — If you live in a region that experiences cold winters, you know the frustration of going out to your car, and noticing that your windshield is obstructed — most often by a layer of frost.

For those who find themselves unable to drive, because they’re unable to see outside the car, you’re stuck waiting on the vehicle’s climate control system to defrost the windshield (depending on how thick the frozen layer is, it could take quite a bit of time for the glass to clear). If you’re in a hurry or happen to be running late, this game of “hurry up and wait” can be particularly frustrating.

Luckily, there’s an easy, and simple trick that most people are unaware of, that will defrost a windshield, quickly. The best part — you don’t need any tools!

According to Instagram user @modernmilt, to defrost your windshield quickly, simply flip your sun visors down when you leave your car for the day. The next morning, when you turn on the heat in your car with auto-start, the heat will radiate outwards, and the visors will help angle it up so that it stays more on your windshield than it would otherwise. Doing this will significantly reduce the amount of time it takes to defrost.

If you don’t have auto-start, or you forget to pull down the sun visors during the previous day (or night), drivers can simply pull them down after getting in and starting the vehicle. Then, just blast the hot air onto the windows, and you should have a frost-free car (at least on the glass) — allowing you to be driving in no time.

And for those who have a vehicle with a broken climate control system, or don’t have sun visors (for whatever reason), there’s always De-icer.
