    Car windscreen spray to prevent ice/frost

    Has anyone here used successfully a spray that can be put on a car windsreen to prevent / lessen ice/frost - do they work or just leave horrible smears/films. Any suggestions or recommendations?

    Ammonia spray removes ice and frost instantly, if I remember correctly. Doesn't prevent it; you just spray it on when you need to remove the cold stuff.

    Apologies if that's not what you mean/need.

    10 seconds with a scraper works well.

    Yup, that sounds like the stuff. It a revelation compared to scraping or waiting for a car to warm up.

    Sounds good.

    This Carplan De Icer 500ml Spray and this Prestone LOYPDEI0101A Deicer Trigger, -40 Degree C, 500 ml look very much like the spray I was thinking of. I make no guarantees though as I haven't been able to test the two I've linked to.

    Cling film prevents ice. I do not know of a spray.
    RainX also works well.

    Imagine cling film would take ages (or would next morning unpicking the mess on the roll).

    Something like RainX will certainly help and only has to be applied occasionally.

    Not very different to windscreen washer fluid - use that diluted (or not) as appropriate.

    You need a wrapmaster:



    Never had a messed up roll since we got ours 3 years ago. 2 or 3 length slightly overlapping in 1 minutes in the evening. Less than 10 s to remove in the morning and Robert’s your mother’s brother.

    Please tell me you aren't putting several metres of cling film in the bin every day through the winter. You do know that stuff will still be in the ground when your grandchildren's grandchildren's grandchildren are dead?

    Well trained indeed. 😋

    However Landrovers have very small windscreens.

    But you need long arms to reach the center of the screen. Sometimes it's not scraping, it's hacking the ice - especially when the temps have dropped after it has rained the evening before.

    old carpet is better.... less likely to blow off... thinking back to the days when I didn't have a garage - sorry am I rubbing it in a bit too much ;-)

    I apply Angelwax H2Go glass sealant which lasts 2-3 months. This usually results in a fine mist on windscreen or if particularly cold, ice/frost but which does not adhere to the glass and almost slides off.

    I applied it in August and it has now worn off (due to use of wipers) but side windows are relatively frost free. I do not have use of a garage to re-apply but it is very easy.

    At the moment I leave a two litre bottle of room temperature water in the kitchen at night which I then pick up in the morning and slosh it about and I am away in two minutes. I also wind down all windows for a minute or two as I park up the night before, this leaves hardly any condensation in the morning.

    A sheet will go under the wipers and inside the doors easier than carpet,and not as heavy and awkward to man handle than a frozen carpet.

    Check the wipers arent stuck then saucepan of water, from the cold tap, thrown on the windscreen. Jump in,shut the door and turn on wipers before it refreezes.
    Too much haste with the last step and you may get wet.
    Attempt to sneak the bosses best large saucepan back into the kitchen without her noticing when you get back home.
    Alternatively park the front as close as you can to some shelter such as a building or tree/busy if you can.

    Build a wooden trough the width and curvature of your windscreen, attach with HGV straps right over and under the car lengthwise, adjust to secure. Then fill the trough with warm cannonballs, that will defrost your windscreen, voila!

    That's what I've been doing wrong!!
    I have just been putting the HGV straps over the car, not under as well.
    Explains why the cannonballs keep rolling off down my steep hill and I have to call into the blacksmiths on the way to work each morning to order a new batch. Therefore negating anytime saved by not sparing 50p for a plastic scraper and less than a minute of my time in the first place.

    I have NEVER scraped a windscreen... all you need is a 2litre bottle of luke warm water to pour over the windscreen. Takes seconds.

    Added benefit is that it clears the inside of the windscreen too.

    Second this!

    During the winter months I keep a 2l bottle of room temp water in the porch and just start the car pour over the water run the wipers to remove the access before it refreeezes and job done.

    My wife’s Z4 is a right pain to get into, the windows tuck under the top of the roof and if the base rubber is frozen it’s almost impossible to get into the car.

    Trying every option but gummi and clingfilm are the best so far

    Sheet of cardboard cut to the windscreen size and held in place with the wiper blades, and just do the rest with a scraper.

    Tepid water (not hot), very quick and easy and the slight warming effect helps prevent the inside of the screen misting up.

    On the flip side - regarding the after affects of ice, I can thoroughly recommend AUTOGYLM DE-ICER....
    it clears ice much much quicker than any other spray

    Another here who pours warm water on, been doing it for years. Stops the inside fogging up as the glass warms up, defrosts the sprayers too. Would love heated glass, you can get aftermarket heated screens for most cars which is a tempting mod.
