How To Defrost Windshield Without Breaking It
These freezing mornings youre probably finding your windshield frosted/iced over. And youre tempted to throw a bucket of hot or warm water over it.
Dont do it. You might crack your windshield.
You can throw cold water on it, but even better, and safer, says Mike Andrews of Reliable Auto Glass in Rohnert Park, is to start your car, turn on the heater for five minutes, thus warming up the car and windshield, and THEN turn on your defroster. If you turn on your defroster right away, he says, you also might crack your windshield, especially newer cars where the defroster air heats up quickly.
He says that after those five minutes he typically finds he can just use his wipers to push off the ice or frost.
Andrews says this week hes replaced one windshield of a customer who tossed warm water on it and two of customers who had immediately turned on their defrosters.
Its always been the case, said Andrews, whos owned Reliable Glass for about 40 years.
SPECIAL NOTE: If youre letting your car warm up, stay nearby or even in it because every winter cars are stolen here as their owners let them warm up but go inside their home to do other things.
Tips On How To Defrost Your Car Safely
How To Defrost A Windshield With No Heat
Finding frost on the car windshield on a cold, winter morning is hard enough. Driving with ice on the glass is dangerous. But, when there is not heat in the car to use the defroster, its even harder because warm air is required to melt ice on the outside of the glass. Luckily, there are some proven methods of removing frost that don’t require a heater.

To Warm Or Not To Warm Your Car
The Environmental Protection Agency has studied fuel economy under winter conditions extensively. Its findings? Depending on the make, model and other technical specifications of your vehicle, you can expect your MPG to drop between 12 and 20 percent on days when the thermometer doesn’t crack 20 degrees Fahrenheit. However, a variety of factors contribute to this lessening of fuel efficiency. Tire pressure, battery performance and oil viscosity are all affected by freezing temperatures, and all of these individual components can work together to transform even a hybrid vehicle into a gas guzzler.Nevertheless, the EPA still recommends that drivers at least briefly warm up their cars on extremely cold days. As the Washington Post reports, however, sophisticated, computer-controlled fuel injection systems have replaced the traditional carburetor and its more finicky method of achieving the proper air to fuel mixture. Drivers of modern vehicles consequently no longer need to idle their cars for 15, 20 or even 30 minutes before running even a quick errand on a particularly frigid morning. As the EPA notes, in modern vehicles, “the engine will warm up faster being driven.” And, if covered or enclosed parking isn’t an option, you might also consider investing in a weather-proof or insulated cover to keep your vehicle from being completely exposed to the elements.

How Long Should You Warm Up Your Car In Winter
The best source of information regarding whether or not, or how long, to let your vehicle warm up before driving remains your vehicle’s manufacturer. Check the recommendations. And do remember that warming your car up for as little as 30 seconds to a couple of minutes, while it does burn fuel at 0 MPG and increases polluting emissions, isn’t entirely wasteful. Brief idling does help to heat up and distribute motor oil that may have settled into a cold, hard lump overnight. Warming up your car thus helps protect your engine and extend the life of your vehicle. Again, check your manufacturer’s recommendations, and, if you live in a region in which temperatures remain below freezing for extended periods, consult with your mechanic and make sure your vehicle is topped off with the correct motor oilnatural or syntheticdesigned to perform at such temperatures.
Finish Up Before Driving Off
If you’re hurrying to get to work or do the school run, it can be tempting to drive off as soon as the ice has cleared a little.
But this could dangerously obstruct your view of the road if there’s still ice or mist on your windshield. In fact, you can get a £100 fine and 3 points on your licence if you drive with obscured vision.
83% of drivers use a proper ice-scraper and 63% use de-icer. That’s compared to 14% of people who risk a snapped bank card or scratched windscreen by using a credit or store card to scrape away the ice.*
Not everyone bothers to clear all the ice off before they drive off, instead leaving enough of a window to see through. This is known as ‘portholing’ and could get you in trouble with the police if you’re caught driving dangerously.
Make sure your windows are clear and follow our tips for driving in snow and ice to keep safe.

Keep Your Car Safe From Thieves
It can be tempting to leave the car to defrost while you retreat to the warmth of the house. But you’re skating on thin ice if you do.
Thieves see frosty mornings as a Christmas gift, looking out for defrosting cars that have been left unattended with the engine on. The crime even has a name: “frosting”.
Our research showed that almost 1 in 6 drivers leave their engines running and go back inside to wait for the ice to clear.
- Scottish drivers seem to be the most trusting – almost a quarter leave their car with the engine running.*
- Only 1 in 10 of people in London leave their car while it defrosts.*
Unfortunately, you’ll get the cold shoulder from your car insurance company if your car’s stolen that way. You won’t be covered if it’s nicked because you left your keys in it unattended.

Snow On The Way These Hacks Can Prevent Ice From Freezing Your Windshield
If you cannot park your car in a garage or don’t have sheltered parking, you can cover your windshield so you don’t need to scrape it clean.
You can purchase a windshield cover, which protects your windshield and wipers and is held in place by magnets or straps, such as those recommended by Popular Mechanics. They start at less than $10 and can cost $30 or so.
Alternatively, a large towel, sheet or tarp can serve as a DIY windshield cover, AAA says. Use the wiper blades, weights or magnets to hold it in place. Soaking your cover in a solution of one tablespoon salt to one quart water can make it easier to remove, AAA says. You can store the cover in a plastic bag or container when not using it.
Worth noting: If a lot of snow is expected, your windshield cover may not be easy to remove.
You can also pretreat your windshield with an ice and frost shield spray, AAA says. But they can be pricey and some ice prevention products contain ethylene glycol, which is poisonous to pets if swallowed.
To help thwart icing while you are mobile, replace your windshield wiper fluid with winter deicing wiper fluid. And if your wipers aren’t doing their job currently, replace them with heavy-duty winter wipers if you expect snow and ice this season.
If you can’t park in the garage, Sadlier said, these methods “should make dealing with frost and ice less frustrating.”

Can You Pour Hot Water To Defrost A Windshield
The American Automobile Association does not recommend using hot water on a windshield. It can crack or shatter glass due to the sudden temperature change, according to an article from AAA.
Heres how the article from AAA puts it: While pouring hot water over a cars windshield during low temperatures might seem like a good idea, its one of the worst things you can do, according to AAA. Hot water can cause your windshield to crack or shatter from the sudden temperature change.
Instead, the AAA recommends starting the engine, setting the heater to defrost, adjusting the airflow to recirculate, and moving the temperature control to full heat. As the ice melts, drivers can use a plastic scraper, windshield wipers, rubber squeegee, or a soft brush to remove any remaining ice off of the glass.
Risks Of Using Hot Water
Grabbing a kettle and pouring hot water onto your frosted windshield might seem the easy solution. Although it isnt the best idea, 15 percent of the UKs Automobile Association members seem to use this method still.
The concept is fairly simple. The hot water melts the ice, and the wipers can be used to get the melted ice out of the way. The sudden change of temperature, however, causes the glass to expand before quickly contracting, which can crack your windshield.
This might make the glass break or chip. Hot water can also drip over your clear coat and car paint. It will remove the protective wax layer and leave stubborn white water marks on the paint.
From a frosted windshield, you might end up with a broken windshield, great paint damage, and an expensive repair bill. Not to mention, potential burns on your hands.
What about warm water? Spilling lukewarm water also have its share of risks. In extreme conditions, warm water can freeze on top of the existing ice layer. Not only will it fail to melt the ice underneath, but water can accumulate around the wipers, damaging their motor and blades.
Alternatively, using a portable heater or a hair dryer would carry the same risks.
Although using warm or hot water isnt the best solution to defrost your windshield, other safer methods are available.
