With the arrival of the cold weather it is very important to have the windshield and wiper blades in perfect condition, especially in areas with frequent snowfalls, rain and fog
During these days it is common that temperatures drop considerably, so it will be common to find ice on the windscreens of cars. At this time of year it is very important to have the windshield and wiper blades in perfect condition, especially in areas with frequent snowfalls, rain and fog.
It is better to take precautions before the cold weather arrives and to replace the wipers at least once a year (you con do it for yourself buying it from any auto parts online store), since if they are deteriorated, when operated they will leave stripes in the driver’s field of vision, putting his safety at risk. It is also advisable to fill the windscreen washer fluid tank with a specific product containing antifreeze.
There are also many homemade tricks to prevent ice from forming on the windshield, especially if the car is on the road at night, although one of the most effective is to cover the car window with a cardboard or a blanket, preventing layers of ice from forming and the wipers from sticking to the glass.
What you should never do
However, if you have not been able to avoid it and find yourself with an icy windshield in the morning, this is what you should never do:
- Pour hot water on the windscreen, because the sudden change in temperature could break the glass, especially if the windscreen is already impacted. The windscreens of today’s cars are constructed of layers of glass and plastic adhesives to prevent them from breaking and injuring passengers. If hot water is poured on the frozen glass, the outer layer will expand abruptly but not the inner one, causing it to break.
- Operate the windscreen wipers and pour water, as water always makes the situation worse and the wiper blades can break if they are stuck to the windscreen because of the ice.
- Add salt, as salt prevents freezing, but does not thaw. In addition, it can scratch the glass and corrode the sheet metal.
How to remove ice from the windshield correctly
To remove ice effectively, the easiest way is to clear the snow by hand until only ice is left and then start the engine, turn the heater on with the fan at maximum and direct the airflow towards the windscreen. Never wait for the engine to warm up before turning on the heater, as the sudden change in temperature can break the glass. With a little patience, the ice will eventually come off.
If the ice layer is too thick or we can’t wait:
- Use a defrosting product. There are many options on the market, although this is the most expensive solution.
- Spray the windscreen with alcohol, as it has a lower freezing point than water. This is a good solution if the ice layer is not too thick; otherwise, you will have to use a scraper to remove the ice. Never fill the windscreen fluid reservoir with alcohol, as this can damage it.
- Scratch the ice that’s stuck to the glass. It is best to do this with a plastic scraper, although if you don’t have one, you can use a CD case or any plastic card or card with little value. It is not recommended to use metal instruments or materials that can scratch the moon.
After removing the ice and removing the wiper blades from the glass (never before!), you can operate the windscreen wiper and liquid dispensers to leave the glass in perfect condition, provided that the liquid tank contains an anti-freeze product.
In bad weather, it is also essential to remove ice from the headlights. In cars with halogen headlights, it is sufficient to switch the lights on for a short time; in cars with modern lighting technology (usually LED), however, the ice must be removed by hand.
