Tips on how to quickly demist your car windows 0
At this time of year, when the temperatures start to drop, the problem of misted up windows starts to become a real pain. There are a few things you can do to speed up the process. Here are some tips to help you avoid sitting on your driveway for ten minutes before you can go anywhere.
- Put your heater on full. This won’t start to work for a couple of minutes, but when it does, it will sort your windows out quickly. Warm air is able to absorb much more water than cold air, so it will draw the moisture from the windscreen.
- Turn on your air-conditioning. Air-conditioning dries out the air before it leaves the vents – so it’s then able to absorb more liquid.
- Turn off air-recirculation. Outside, the air will be cold – and won’t contain so much water vapour. Piping it into the car will aid demisting.
- Open a window. Again, this brings in the dry air from outside – ready to be warmed up and absorb moisture. You don’t need it all the way down, just a crack will do.
- Stand outside the car. Your breath is warm and wet so won’t do much in the way of aiding the demisting process.
In many cases, your car’s automatic systems will be more effective – many modern cars even have a ‘demist’ button handily positioned on the dashboard. Many cars also have heated windscreens that can demist a fogged windscreen in seconds.
There are a few other tips. Many companies sell anti-fog liquid that stops the windows misting up. A cheap alternative to this is to rub your windows with shaving foam – which seems to work just as well.
Another trick is to stop the car getting humid in the first place. It’s possible to buy dehumidifiers which absorb the moisture before it hits the windscreen. Or, if you’re on a tight budget, try filling up an old sock with cat litter and tying off the end.
Whichever approach you choose, remember not to move off until your glass is clear. It’s dangerous and if your visibility is impeded, it’s illegal.
