Let's say I've ignored their advice and woken up with a thick coating of ice on my windshield, as I did yesterday.
What's the fastest way of getting rid of it all so I can get to work on time?
If you have a heated windscreen, stick that on first, it'll loosen the ice from surface it's stuck to and it'll just slide off with a little push. If you don't have heated windscreen, still stick your heaters on full and point them at the windscreen. Any heat is going to help.
With a scraper, work from one side and make sure you're scraping underneath the ice, removing the problem from the source, not just taking layers off.
De-icer spray works from the top, so I don't think it's that brilliant. But if you have any, it's not gonna do much harm. It may be useful if the ice is being pretty resilient.
Finally, don't forget to de-ice your lights! Turning your lights on while your doing your windscreen will probably warm up the ice enough that it will have fallen off by the time you finish.
I've used the spray cans of de-icer and they work great. Looking at the ingredients, they used forms of alcohol to get the job done. So I tried the spray of 2:1 rubbing alcohol to water and it worked great. I know some people who have even added it to their washer fluid tank directly.
I would advise against using warm or hot water on the window. You may get away with it 10 times, but I have seen someone use that method and the temperature difference was so far apart and the change in temp so quick that the glass cracked.
I would prefer you to wash your cars window using water with a hose and it can do the trick unless atmosphere temperature solidify this water(which means if your regions temperature is too low, this can not become practical).
Another option is to sprinkle table salt on it, this will melt the ice off and it is economical too.
Sounds like a good problem for an extension cord and a BlowDryer.
I know this is an old thread, but I've had amazing results with using RainX. It helps prevent snow, freezing rain, and ice from accumulating. Even when it does build up, it makes it Much easier to scrape off. RainX brand also makes defroster sprays that work well to help break up accumulated ice as you scrape. It has RainX in the deicer, so it also helps to maintain the RainX on your windshield. This trick works so well that I use it on all of my car's outward facing glass, including side mirrors.
As mentioned in other answers, using the car's defroster setting is a good add to the procedure.
Using all of these options gets the ice started to be removed from the glass from both sides of the ice. This greatly improves your ability to scrape it off with an ice scraper.
I first added RainX to the ice scraping routine almost 2 decades ago. The ice that winter was as thick and hard as I remember ever seeing. I broke countless scrapers, to the point where I would buy 2-3 ice scrapers every time I saw them available. We're talking +3/4" ice every morning and every night for at least a week, and that was under +6" of snow drifts on the car. Sometime during that week, I applied RainX to my windshield, side windows, and rear window. The next time I had to scrape, the ice came off in large chunks, instead of finely shaved ice. I didn't even break the scraper!
When I found the RainX brand deicer years later, I got some and have now been using it for many years. It works great on frost as well as thick sheets of ice. I even use it in the summer to put down a quick layer of RainX. For $4 a can/bottle, I feel it's well worth freezing my fingers less and getting to work sooner. I used to give it as Christmas presents!
As an added bonus, RainX works while you're driving. It lets your wipers remove splashed slush, falling snow, etc. better. If you turn up your front defroster, the snow that turns to water slides off really easily. RainX brand also makes a wiper fluid that has RainX in it, which just so happens to be rated down to negative thirty-something degrees Fahrenheit, which helps keeps your windshield coated with RainX and free from freezing sh-tuff.
Full disclosure: I'm not in anyway endorsed or paid by RainX, I just really love what it does for me.
Water and vinegar on the windshield is supposed to de-ice a windshield.
Origins: Claims about using a mixture of vinegar and water to remove ice from a car's windshield hit the Internet every year around the time of the first freeze in mid- to late-autumn. In recent years this advice has been widely spread as information suggesting that spraying vinegar and water (mixed in a 2:1 or 3:1 ratio) will remove ice from an already iced-over windshield, but the tip originated not as a de-icing method but rather as a way of stopping ice from building up on a windshield in the first place, as noted in a 1992 newspaper Read more at http://www.snopes.com/inboxer/household/vinegar.asp#g2YAmZvvTbC6y0MF.99
However some say it pits the windshield.
A 1980 "Hints from Heloise" column advocated the same idea: Looking at the world through cloudy, streaked windows? Clean them with a mixture of vinegar and water. Same with the windshield. Vinegar also helps retard frost on those cold mornings if you pour it on the windshield the night before (three parts cider vinegar to one part water). The issue of whether this method of ice prevention will indeed pit windshield glass is a matter of contention, with some cautioning that it does: Pour a mixture of vinegar and water on the windshield so that it freezes to the glass before the rain does, thereby preventing ice. Unfortunately, vinegar eats pits into the windshield glass.
I'm assuming keeping the car in a garage isn't an option, so . . .
I like the rubbing alcohol and water solution (2-2) and the tip to put rubbing alcohol into the washer reservoir (3-3). Going to try it this year rather than buying commercial solution. Hopefully it will work as well as it does in the video I saw. I'll do it with the heater/defrost on full blast to give it a little extra help.
A NYLON comb makes a great, easy-to-find, and effective ice scraper in a pinch. Nylon is strong and does not damage the parts of the car that you might hit while you work. No pots of hot or boiling water, electricity, or chemicals needed.
When you're finished, you can still use it to smooth your coif after the workout. : )
FYI: Born in Maine, I live in Montreal, Canada where salt water freezes
if you have a good car scraper, and theres thick ice on the windows, don't use the flat side of the scraper. use the back side of your scraper which should have some flat bumps on it. use long strokes and and forth over the windows with this side, which will get through the ice quick. do the whole window this way first and resist taking the ice off completely. then flip it over, and scrape with the flat blade. it should come off very easy. i just did my sedan which had a quarter inch of ice on it in about 5 minutes, and some people had been scraping for half an hour.
These can all work as deicers in a pinch.
