How to Defrost Car Windows Fast: Tips and Tricks

Welcome to our article on how to defrost car windows fast! As we all know, the winter months can be brutal, especially when we’re in a rush to get to work or school. One of the biggest challenges we face during this season is defrosting our car windows quickly and efficiently. In this guide, we will walk you through 12 easy steps to defrost your car windows fast, with additional tips and tricks for good measure. So without further ado, let’s dive right in.

Step by Step Guide to Defrost Car Windows Fast

Step 1: Turn on the Car

The first step is to start your car and turn on the engine. This will generate heat and help to warm up the car’s interior. Additionally, it will activate the defrost system which will begin to warm up your car’s windows.

Step 2: Turn on the Defrost

Most cars have a defrost button that you can press to activate the defrost system. If your car doesn’t have this feature, simply turn on the heater and select the highest temperature setting. This will blow warm air onto your car’s windows, helping to defrost them more quickly.

Step 3: Turn off Air Recirculation

Make sure that the air recirculation button is turned off. This is because recirculating air will only circulate cold air, which will make it harder for your car’s windows to defrost.

Step 4: Turn Off the AC

Turning off your car’s AC will help to make sure that warm air is blowing onto your windows. Moreover, running the AC on a cold day will only make your car’s interior colder, making it take longer to defrost your windows.

Step 5: Adjust the Fan Speed

Adjust the fan speed to a level that feels comfortable for you and according to how much heat you want or need. Remember that turning the fan speed up too high will cause the hot air to blow straight onto your windshield, and this can cause it to crack. As a rule of thumb, always keep the fan speed at medium or low level.

Step 6: Clear off the Snow and Ice

Remove any ice or snow from your car’s windshield, windows, and mirrors using a scraper or a snow brush. This will expose your windows to the warm air and aid defrosting.

Step 7: Use a De-icer

Apply a commercial de-icer spray to your car’s windows and windshield. The de-icer helps break down the layer of ice on your windows making it easier for the warm air to do its job.

Step 8: Use a Windshield Cover

Invest in a windshield cover if you live in an area where snow and ice are a common occurrence. The windshield cover helps to protect your car’s windows from being covered by snow overnight, saving you time on defrosting.

Step 9: Cover Your Windshield Wipers

Covering your windshield wipers with socks or plastic bags overnight will help to prevent them from freezing onto your windshield.

Step 10: Use a Hairdryer

You can use a hairdryer on its highest heat setting to defrost your car windows quickly, but it’s important not to get the dryer too close to the windows to avoid causing damage.

Step 11: Use Saltwater

Mix up a saltwater solution in a spray bottle and spray it onto your car’s windows. This will help to melt any snow and ice on the windows quickly.

Step 12: Wait It Out

If all else fails, you can opt to wait until the sun comes up to help melt any ice or snow that may still be on the windows. Park your car in a sunny area and be patient.

Tips & Tricks

Tip 1: Use a water repellent on your windshield

Use a water repellent spray on your car’s windshield to help expedite the melting process. The spray helps to prevent snow and ice from sticking, making it easier to remove.

Tip 2: Dampen a towel and lay it on the windshield overnight

Before going to bed, dampen a towel and lay it on your windshield. The towel will help to hold in the heat, and the moisture will attract cold air, quickening the defrosting process.

Tip 3: Use warm water

Use warm water to pour, not throw, directly on to the windshield. Winter temperatures can cause sudden temperature changes, which could break the window; so, it’s essential to apply it slowly and gently.

Tip 4: Put your windows down slightly while driving

Leaving your car windows slightly open while driving will allow any air trapped inside to escape, reducing condensation which means icy windows the next morning.

Tip 5: Clean your car’s interior windows

Cleaning the windows from the inside using a microfiber cloth and glass cleaner can help to reduce the amount of condensation on the windows, reducing defrosting time.

Tip 6: Rub an onion on the windshield

Rubbing an onion on your car’s windshield will help to create a water-repellent barrier. This trick will promote easy removal of snow or ice that has accumulated overnight, and save you time on defrosting.

Tip 7: Keep an ice scraper in the car at all times

This may seem like a no-brainer, but having an ice scraper at all times ensures that you’re always prepared.

Tip 8: Park your car facing east

The sun rises in the east, parking your car facing east will ensure that your car windows are exposed to sunlight, providing natural warmth that can defrost your car windows.

Tip 9: Don’t sprinkle hot water on your car’s windows

Pouring hot water or throwing boiling water on a frozen window can cause it to crack or break entirely. Avoid this at all costs.

Tip 10: Schedule your defrosting time accordingly

Knowing what time you need to leave in the morning and giving yourself plenty of time to defrost your car way less stressful than running late. Always set a reminder and wake up earlier to allow yourself enough time so you can defrost your windows safely.

We hope that you find our guide useful and that it helps you to defrost your car windows quickly and safely during the winter months. Keep warm and stay safe!
