One of the most common problems among many motorists is low visibility especially at night when snow can easily blur your windshield. If you do not have the proper tools and supplies to de-ice your car, then the likelihood of you getting into accident is relatively high. Here are some of the important things you should do to prepare yourself from potential problems such as unfreezing your door locks and defrosting the windows:
Always keep a de-icer spray and a couple of window scrapers in your car. Ideally, you should at least keep one set in the car and another set at home. This can help you easily remove the frost in your window even during heavy snowfall. You may also want to consider buying an all-weather windshield screen. It will protect the windshield of your vehicle from extreme frost and can still be useful during summer to shade the interior of your car from sunlight.
Another way to easily melt the ice in your windshield is with the use of boiling water. Just simply pour it over the windows to defrost them. Although in some other cases this method is not advisable because this can cause a crack after two extreme temperatures meet. You only have to be very careful when using this method because it can freeze on the ground and form an ice slick.
Perhaps the best way to defrost a car and keep the interior warm is through a car heater. This device uses a small amount of electricity, and can easily melt the ice in the windshield for a few minutes. Just make sure that you connect it to an extension lead intended for outdoor use (this one is proven safe because it is protected by an RCD [residual-current device]). When not in use, lift the wiper blades away from the windshield and rear window to keep them from freezing.
In case your door lock is frozen, you can unfreeze it by warming the key gently prior to inserting it. You can do this by simply placing it on a radiator or using a lighter flame. Aside from this method, you can also spray a littler de-icer into the lock. For frozen windshields, all you have to do is to spray the de-icer on the jets or carefully clear the nozzles with a pin before you drive off. Lastly, do not forget to defrost the exterior mirrors.
