Clearing ice/frost off windows before you move off:- The Motor factors across the country would want you to spend thousands of pounds clearing all of your glass with their spray de-icers... Get a good quality ice scraper and a thick pair of gloves to scrape off the majority ice/frost. Use sparingly the De-icer and spray it over your wiper blades and make sure they lift off the windscreen before you move off and on the rear wiper if you have one. This saves burning-out expensive wiper motors, blowing wiper motor fuses and/or damaging wiper blades. Use again (sparingly) the De-icer spray it into the very top of your drivers and passengers side windows, should you need to open either of these windows you will again save on burning out expensive electric window motors and fuses. Also, spray some of that De-Icer onto your washer jets.
DO NOT pour hot water on any glass with ice or frost, the rapid change in temperature could cause the glass to crack.
On the move keeping the windscreen free of ice/frost/salt:- Whilst on the move and the first few miles behind another vehicle the screen has salt on it.......... the temptation is to operate the windscreen washers, but because the water in the bottle or at the jets has frozen to ice nothing happens... Well something does happen and the little item that protects all electrical circuits on the vehicle, i.e. the washer motor fuse, blows. It is worth identifying where this fuse is fitted on your vehicle, checking your handbook and purchasing a few spare fuses for the cold weather.
Expensive prestige vehicles have small heater elements in their washer bottles and quickly turn the ice back to water then switch off again when the water temp reaches a given point.
Less expensive vehicles have nothing but you can purchase these heater element kits and fit them yourself should you be that way inclined.
Another way to help prevent the water from freezing is to use a higher concentration of washer fluid with an antifreeze content but in extreme cold not even this works. Go to your local garden centre and purchase one of those pump action spray gun bottles, fill it with a high concentration of washer fluid, you will have to stop when you screen is covered with too much salt but at least you can spray it on the screen to see and be safe. Sadly until the water defrosts in your washer bottle you may have to stop a few times especially on a long journey but again you will be safe. The same spray gun can be used to clean off the salt from your rear and front lights and number plates, so that you stay safe and legal..!
