How To Defrost a Car Windshield Quickly

How To Defrost a Car Windshield Quickly

“You might familiar with the annoyance of your car’s windshield covered in frost under a thin film of ice when you wake up and already late.”

Then, defrosting the windshield can be another challenging task. To overcome this situation scraping the windshield can be one option that requires you to work hard outside in the cold.

Alternatively, you may turn on the defroster with a running engine every time. But this would be a time and fuel-inefficient approach.

For defrosting your car's windshield, there are several options that you can check by continuing to read this blog.

Ways to defrost your car windshield in Surrey, BC


You might begin noticing that your car windows require a little care before you go to work in the morning as the season changes and the temperature decreases.

Fortunately, several approaches can solve the issue and get you back on the road without incident. In the sections below, we'll go over tried-and-true methods for defrosting windshields and avoiding future freezing incidents

Defrost windshield with lukewarm water

Fill warm water in a gallon-sized bucket 3/4 of the way. (Never use hot water to defrost a windshield; the temperature difference will cause the glass to expand and, in some cases, break.)

Carry the bucket to your car, start at the top left or right corner, and slowly pour water horizontally on the frozen windshield.

The ice in its path will instantly melt as the warm water drips down, turning it into an impenetrable slush. Run your windshield wipers, or use a gloved hand to clean the windshield.

To defrost iced-over other windows of the car, use the remaining warm water; just ensure the windows are fully closed first!

Use Rubbing Alcohol to Defrost a Windshield

Because it has a considerably lower freezing point than water and treats minor scrapes, the alcohol you use to de-ice your car is also a good de-icer (minus 128 degrees Fahrenheit).

Alcohol's heat is transferred to the ice, raising its temperature and melting it. Follow these steps to use this method.

  • Add four ounces of room-temperature water and eight ounces of rubbing alcohol to a dry 12-ounce spray bottle. The mixture should then be replaced with the spray head and shaken several times to blend.
  • Spray the solution all over your windshield to completely cover the glass, then let it sit for a minute to let the alcohol permeate and melt the ice.
  • With gloves on, either wipe the frost away or use a plastic credit card to scrape it.


To melt the ice on your windscreen, mix a tablespoon of salt with two glasses of water and sprinkle it on the surface.

However, be careful not to spray this mixture on your car's painted parts as salt can accumulate over time and start to eat away at your paint job, exposing the metal underneath and leading to rust. It is the easiest and most practical way to get rid of frost windshields.

Windshield Defrosting with Homemade Heat Packs

Do you like to de-ice your windscreen inside the cozy warmth of your car? Put two worn-out socks or mittens loaded with uncooked rice in the microwave for 30 seconds.
Grab one heated sock in each hand and gently run them over the entire inner surface of the windshield glass while seated in your car.

Note: Take care not to leave the heated sock in any area for longer than 10 seconds (this can increase the risk of the glass cracking).

The rice's heat will convect to the glass and begin to melt the ice on the windshield. Run your windshield wipers to clean the slush off the windshield once the frost has melted or sufficiently softened.

A warmed water bottle

Another prominent option is a hot water bottle filled with boiled water and diluted with a portion of cold water.

By starting with it, diluting and gradually reducing the amount of cold water added to the mixture each day help you to test how much hot water is safe to use on your windows.

While you're seated in the car, slowly move the hot water bottle across the interior of your windows, it will start melting ice and you can restore your problem.

This method has the added benefit of leaving you with a hot water bottle to keep yourself warm while traveling once your windows have been defrosted.

How to Prevent Frosting on a Windshield

Apart from curing your windshield repair from frosting, it's better to take some measures to prevent it from frosting. There are a few strategies you can use:

  • When parking your automobile during the colder months, keep all of the windows closed.
  • If you don't have indoor parking, you can use your wipers as clips to put a tarp, beach towel, or a few rubber mats over your car's windshield. They will serve as a shield, gathering ice and frost while the glass below is kept spotless.
  • To prevent dew and snow from getting to your windshield wiper blades and causing them to freeze in place on the glass, lay an old stocking or knee-high sock over each one.

If finding any problem related to your car’s windshield - do not worry.
