The Dangers of Frosted Windshields 

Before discussing how to defrost your windows it’s important to understand why it’s so important. Your windshield is designed to protect you from all sorts of harm such as weather conditions, flying debris, and injury in case you get into a collision.

Despite this, windshields are actually incredibly sensitive to temperature changes and can be damaged by exposure to extreme temperature differences. Your windshield will contract and expand when exposed to heat too quickly and this can lead to lasting windshield damage.

Because of this, you should never use boiling water to defrost your wind! This could lead to serious damage to your windshield down the road.

How to Defrost your Windscreen and Rear Window

  • Use de-icing spray 

There are a number of chemical deicing sprays available on the market. Head to any hardware store and you’ll find a number of brands to choose from.

If you don’t want to use chemicals on your windshield, you can actually make your own de-icing spray. Simply mix 1/3 of a cup of water with 2/3 of a cup of rubbing alcohol and spray it directly onto your windshield. 

You can also make a “preventive” spray that will prevent your windshield from frosting up in the first place. Mix 2/3 parts white vinegar to ⅓ part water and spray it on your windshield before the temperature drops in the evening.

  • Switch on the engine 

The easiest way to defrost your windshield is to turn on your engine and then turn on the warm air blower towards the windshield.

If you have a rear windshield warmer, turn it on. Turn on the air-conditioner too. It’s not just for the summer months, it’ll actually help remove moisture from the air and prevent the windows from misting up.

  • Sweep off the snow

If the top of your car is covered in snow, it’s important that you sweep it off. Not only can you actually be fined for not removing the snow, but it can also be extremely dangerous.

While you’re driving, snow from the top of your car can fall onto your windshield and block your view.

While your windows are defrosting, use a soft brush to clean the front grille (to prevent the engine from overheating) and remove all the snow from the top of your car. Make sure to brush off any snow from your lights and rearview mirrors too.
