Any good method to prevent windshield frosting in cold weather?

I meant the out side of windshield (NOT inside). I get up and leave for work 7:30 in the morning, sicken tired of chipping off that thin layer of ice/frost on my windshield. And it's there every single day! I tried white vinegar last night, didn't work, will try onion tonight...

Honestly, go fill your wiper fluid jug with RainX winter formula wiper fluid (color is orange creamsicle-ish)

Start the truck and let it warm up a bit, turn on front defrost then before you drive off hit the windshield with a quick spray. It might freeze a bit but it should get rid of most and if you have at least some warm air going on the windshield it should clear up pretty quickly.

careful with the rain x i found if it sits it wil clog up the wiper lines and pump as it has wax in it
Correct! Many posts about RainX killing the pump.

MANY years ago when I was stationed in North Dakota I installed something like this in my truck and tied it into my block heater plug. From that day on, I NEVER has to scrape my windshield. It doesn’t keep it hot in there, but it keeps it warm enough for the windshield not to freeze up.

Vinegar was the wrong solution. Try 70% isopropyl alcohol(2 part alcohol/1 part water)

Honestly letting it run for at least 10 mins in that weather is the best way. Before I had a remote starter put on I always went outside and started it manually 10 mins before I had to head to work.
And if you have to modify a stair rail to fit it in your garage I'd be all over that.

Plus letting the engine warm up and get all the juices flowing before you take off is better for the engine.

Now to wait and see how many people say that consumes to much gas. :popc1:

Absurd, what is the point of such a law?

I use a windshield cover on mine. It has straps that go around the mirrors to prevent it from blowing away. In the morning I take it off throw it in the truck and drive away with no ice on the windshield to deal with.

How to Quickly Remove Ice From Your Car Windows

Fill up a spray bottle with two parts rubbing alcohol (70-percent isopropyl alcohol) and one part tap water, says David A. Katz, M.Sc., a chemistry professor at Pima Community College in Arizona. Keep it at room temperature—not in your car—between uses.

Spray the mixture on your windshield and the ice will start melting immediately. Let it sit for a minute, then use your scraper to wipe off the ice, Katz says.

The mixture’s warm temperature causes some of the ice to thaw. Heat then transfers from that melting mess to the unbroken ice around it, which triggers even more melting.

So why not just splash regular room-temperature water on your windshield? While warm H2O would melt the ice, it’ll just freeze again, Katz says.

The rubbing alcohol/water mixture has a much lower freezing point (5 degrees Fahrenheit) than water’s 32 degrees. That means it won’t refreeze on your windshield unless the temperature outside dips close to 0 degrees, he explains.

=======================================

The 3 minute rule is for diesel engines with Turbos
It comes from Truckers pulling off of the Highway & into a parking lot & immediately shutting the diesel engine Off.
Doing that ruins the TURBO fairly quickly, because TURBOS need a stream of oil to cool down the fins in the turbo. Shutting off the diesel engine, cuts the oil off & the Bearing within the Turbo burns out due to no lubrication.

Truckers are suppose to pull into the parking spot & watch the trucks Pyrometer until it gets down to 3 or shut it down after 3 minutes. Whichever comes first.

What happened is when some paper pushers heard about those diesel engineers recommendations, they put 2 & 2 together & used it to combat air pollution.

Now truckers have to shut the diesel down after 3 minutes & at this time of year they would freeze their asses off while sleeping in the semi truck at night.

Now Trucking companies have to install an APU, auxiliary power unit, for heating & cooling
It can be powered by battery power, or small engines that have 1, 2, or 3 cylinders using gasoline or propane.

I have been watching the Weather Channel
One thing that i have noticed with snow covered vehicles
No one lifts the Wipers off of the windshield when they park & it is snowing or going to snow.

I recall when i lived where it snowed, my family always lifted the wipers away from the windshield.
Doing that made clearing the windshield easier & the wiper rubber didn't freeze to the glass

Excellent! I really like how it covers the windshield wiper area as well. Seems like it would hold up in high winds as well.
