Defrosting your car correctly
This time of year can really be irritating for commuters of all transportation, but nothing is more pain staking than having to set you alarm an extra 30 minutes early so you can de-ice your car while still having to go through morning rush hour traffic. Hopefully, these tips will help makes those mornings go a little bit smoother.
Tips for a clear wind screens:
While you use a scraper and de-icer on the outside of your car, starting the engine, switching on heated rear screen and mirrors and allowing air-conditioned air to circulate to gently warm the glass is the most effective way to clear frosted glass.
Stay with the car all the time – if you must go back indoors switch off and lock the car.
Do not drive off until all of the glass is clear
Remember not to leave wipers in ‘auto’ when frost is expected – if wipers are frozen to the glass the wiper motor could be damaged. Don’t try to force frozen wipers off the glass.
Never use just-boiled water to clear glass – it could crack the glass, freezes quickly and could ice your wipers to the glass.
Clear all snow off the car, a soft brush is effective – making sure the front grille is clear (otherwise there is risk of the engine overheating). Make sure lights are clean and working.
Air conditioning isn’t only for summer – it will help to dry the air and keep cold glass mist free.
Don’t use your hands to wipe misted-up windows – you’ll leave greasy smears and a diamond ring could scratch the glass. Use a lint-free absorbent cloth if necessary.
