A recent TikTok video went viral showing a person using boiling water in a bag to defrost a windscreen. While this may seem like a quick hack, it can prove to be dangerous and may lead to cracking of the windscreen.
So before you make that essential trip to stock up on some groceries, here are some helpful tips to safely defrost your windscreen:
- Before starting your vehicle make sure your wipers are turned off, as they may be stuck to the windscreen
- Start up the engine and use the interior heater blower to warm up the windscreen from inside, it will help to slowly but safely defrost the windscreen. If you have them, also turn on the rear window heater and heated mirrors to help defrost the rear window and mirrors.
- Clear any snow off your car with a soft brush, then use an ice scraper and de-icer to remove the frost from the windscreen and windows on the outside as the heater warms up the windows from the inside.
- Wait until all the frost and mist has cleared before setting off.
- Avoid using any sharp objects such as credit cards to remove the frost which could cause damage to the glass. Always keep a dedicated car ice scraper to de-ice! Do NOT use hot or boiling water to defrost your windscreen or windows, it could crack the glass!
- If you know you’re going to use the car the next day on a cold night, cover the windscreen with a dedicated windscreen frost protector.
- Do not leave your car running unattended to keep your car safe from thieves.

When we think about car maintenance, windscreen wipers are probably not the first thing to come to mind. As far as car safety is concerned, this is one of the most important tools to ensure an unobstructed view for the driver. Windscreen wiper blades of your car are used to clear the water from the screen during rain, and also to clear snow, debris and dust when used with the vehicle’s washer fluid system.
Streaks and smears
You may start to see streaking and smearing across the screen during their operation. Sometimes this can be caused by debris that can be cleaned easily, but take a closer look at the rubber to see if there are any signs of it being worn out.
Windscreen wipers are generally silent. You may sometimes hear a squeak or screech which could mean it’s improperly fitted or in some cases is an indication of worn-out blades.
This usually happens when the wipers are unused for a prolonged period of time which can cause improper contact of the rubber with the windscreen.
In this case, you may notice that the leading edge of the blade has started to come adrift from the main body of the blade.
The lifespan of wiper blades depends on the quality, weather and extent of usage but can get worn out in 6-12 months. Make sure you keep an eye on any signs of replacement mentioned above to avoid causing damage to the windscreen.
How windscreen wipers work
The majority of windscreen wiper linkages (the bit that makes them go back and forth) are held together by a simple plastic ball and cup technology. This is fine when the wipers they are propelling can swipe along without hindrance. However, when a wiper is stuck to the screen due to ice or snow, it will place the linkage and motor under increased stress and that can cause the weak point, the ball, and cup, to part company and when that happens there is no alternative to either replacing the parts or getting a temporary fix done. This, of course, is both costly and inconvenient as you will not be able to drive the vehicle without working wipers. Depending on your car, repairing the windscreen wiper linkage starts at £100 and goes up to costs of £300 or even higher. Faulty windscreen wipers can also land you with a hefty fine if you are stopped. But it doesn’t stop here as damaged wipers will also put passing the MOT the first time into jeopardy if they fail to clear your windscreen for visibility.
Taking care of your wipers
Whenever you end your journey, make sure your wipers are turned off before you stop the engine. This will not only allow them to park in their correct position but ensure that they do not try and move the moment you start the car the next time.
If you forget or cannot remember if you parked the wipers and there is a hard frost, lift the blades off the windscreen before you start the car. They will still judder across the frozen surface which doesn’t do the wiper blades any good, but at least it prevents the linkage being damaged.
PS – Don’t forget the rear wiper too if you have one!

Making sure that your windscreen wiper blades are in good condition is vital at any point of the year, but especially in winter. Sometimes that means you will need to replace your wiper blades. Remember, your wipers are the only parts that can help keep your windscreen clear of debris and water during bad weather conditions. They can help improve your vision of the road and help keep you safe.
Signs That The Windscreen Wiper Blades Are Worn
Over time the wiper blades will deteriorate as it copes with a variety of weather conditions and debris. From hot weather to freezing temperatures, all can have a different effect on the parts. There is a couple of things that will tell there is a problem with wipers.
1. Slow and erratic movement
If your wipers don’t move across your windscreen smoothly it’s likely that the rubber on the blades has worn away. It’s important to get this addressed as it may have a knock-on effect on, for example, the wiper motor. It will have to work much harder with the increased resistance and may wear out too.
If there is a squeaking noise coming from the wipers it is possible that they have worn. That said, wipers can also make a noise if there isn’t enough water on the windows for the wipers to process.
Wiper blades can sometimes get damaged due to debris. The rubber might wear away in places in the process. Often this will lead to the wipers not being able to remove water on the windscreen in a single sweep. In that case the wipers will leave behind streaks on the window.
4. Visual damage
Another good way to find out if the blades need changing is to simply look at them. Often it’s easy to find out that way if there is something wrong with the blades. Damaged edges or brittle rubber will mean that the wipers won’t be able to clean the windscreen effectively.
If the wiper blades are not replaced from time to time, they can eventually damage the windscreen glass as well. Keeping in mind that a set of wiper blades is way cheaper than a new window it makes sense to replace them timely. If you’re not sure whether yours are worn then get a mechanic to look at them and replace them if needed.
