PrestoneTrigger De-Icer 500ml x2 + Spray Can 600ml x2

First discovered this product from it winning an auto express test - always use it now

I always used to forget to buy deicer until you really needed it and you end up forking out £5 for a substandard can of the stuff.This is hands down the best stuff i have used i really prefer the spray bottle because i dont think manufacturers have quite grasped that when its cold enough to freeze your car it makes metal very cold to the touch.This stuff works in no time at all and i wont be changing anytime soon.

I've found the best way to use this is to lightly score the frost with an ice scraper, then spray with Prestone, turn engine on to heat the inside of the car for a few minutes, then use the windscreen wipers (front and rear) to clear the windscreens, and you are good to go. This is the best deicer I have used, very quick and easy.

The aerosol is fantastic, but I wouldn't recommend the spray. Both leaked all over my car despite being stored correctly with it screwed shut and nozzle "off". The formula works brilliantly for both, but because of the packaging for the spray it looses a star.

It's got very cold here lately and my car doors have been frozen shut. Thus has worked a treat to allow to open them and defrost the windscreen. It's probably one of the better brands I've used.

Best on the market. Saves you money in the long run as you don't need liads

Very Quick to defrost tends not refreeze like some do

really fast acting, i keep one set in the car and one in the house just in case the car doors fully freeze shut. The solution works really quickly.
