Using heat gun to defrost windows?

[SSSnail]

C5 Corvette windshields are pretty easy to crack, they are thin to save weight and are also made a bit differently for the HUD.

I thought only the back window is thinner, because the front glass has to meet certain safety standards. And if they are, they won't crack if you pour luke warm water over it to defrost.

If you live anywhere that water will just freezes immediately when you pour it over the windshield to de-ice, you need to move to a warmer place.

And no, your windshield won't crack if you just pour luke warm water over it, if it does, you have shitty windshield and it's time to get another car.

immediately no?

like I said, its going to run into all the cracks on the car, and then refreeze.


and freeze on the driveway

its been below 10F here for about 2 weeks now, the ground is frozen, the roads are cold as hell ETC

you dont add water to an object thats sitting at 30F, its just silly.

a girl on my local motorcycle board used hot water to unfreeze her triple tree, and she ended up having the key frozen in the ignition after about an hour

I do agree it wont crack through, beyond being a really bad idea



ice scrappers cost like 4 bucks......

Just put cardboard saturated with a water/vinegar mixture on your windshield the night before and you'll be fine.

Disclaimer: DO NOT ACTUALLY DO THIS.

What does this end up doing?

I did not try it yet as it seems the inside frost went away magically overnight, but I don't think it will work. I figured a heat gun would clear the ice out of my gutters in no time, and it did nothing but get it a little wet! So if it can't melt ice in gutters I doubt it will do much to a cold car, but I'll have to try it anyway next time I get ice on it.

It will also go well to melt the snow that gets where the wipers are, if it does work. It's impossible to get in there with the snow brush because of how my car is made so it ends up accumulating and is not very good for the wiper motor.

And yeah what does that vinegar cardboard thing do? I'm curious now. I'm guessing it peals off the "plastic" that is on the windchill?

You end up with a frozen stuck-on piece of cardboard on your windscreen...

A joke?

Vinegar/water = summer's eve. Summer is warm so no freezing! :sneaky:

Weird double post.

Seriously? Warm/hot water on a frozen window? Now I'm from Texas and have never had a window frozen enough to require more than a 15 second scrape/windshield wipers to clear up, but I have always been told warm/hot water will crack/shatter glass.

I haven't try hot tap water on cold/frozen wind shields beyond -14C (6.8F for the metric impaired), and I haven't once crack a wind shield or window yet.

I do agree it wont crack through, beyond being a really bad idea

4" & 8" drywall tapping knife take less than 1/4 the time to scrape than ice scraper. Hot tap water clears frost instantaneously compare to scraper/running engine. Thawing out frozen/lock with hot tap water take less than 5 second in any condition.

Well, whatever floats your boat... I live in Southern California right now, and it's ~80 degrees today.

On the rare occasions that I have frost on the windows on the cars parked outside, I dump a bucket of water on the car, the proceed to drive. Like I said, you guys need to move to a warmer place, screw all that scrapping stuffs in freezing ass weather. If you feel like standing outside turning into a snowman scrapping your auto glass, while your car is warming up, more power to you.

Sucks to be you. And NO, it's not a "really bad idea" to dump water on your windshield to defrost.

I wouldn't be terribly concerned about water getting into the engine compartment or between cracks on the front of the car, because, you know, there is a 200F engine in there.

Water in the cowl vents might be problematic for your HVAC system if it freezes in the vent.
