Same story as everyone: park outside at work, drive home in the wee hours, lazy.

I know about putting a blanket or something over the window before it freezes. I do that when I'm home, but my car already collects moisture so I worry about throwing a damp towel into the back while I blast the heater. Keeping a wet blanket in a sealed container is just starting a mold farm.

It's not bad enough here (and I'm not lazy enough) to call for that spray-can de-icer, especially not every single night.
 
Solution
To help prevent moisture buildup, use rainx or some other hydrophobic sealant. If you don't have any or are too poor (not judging, I get it), cut a spud in half and rub the exposed inside part on the windshield. The sugar and starches perform a similar, if less effective, function as the rainx. Canned or bottled deicer is a scam, make your own. I do it in big batches, 2 quarts of isopropyl alcohol to 1 quart water. I do this because it's cheaper to buy the bigger bottles of alcohol and the one quart ones make the most sense. Mix well and just fill up any spray bottle you have and go to town. If you live in an area like I do that receives ice storms and frequent freezing rain in the winter, and you encounter an extra thick sheet of ice...
Best solution I've found is to put rain repellent wax on the windscreen and back window (local trade name is C-Thru, probably called something else in the US) which stops condensation from staying on the windscreen.

Pouring lukewarm water over the ice to melt it also works if you can't get something like that.

I'd advise against a heat gun or similar implement - my uncle tried that and his windscreen bent and popped out of the holder.

I have Rain-x on my shopping list, but man, something about "use a potato" is really enticing.

Concerned it's just a trick to have a gang of Irish steal my windshield, though.

Tried this out, but of course the ice wasn't heavy on the night I was ready for it. It did make it a snap to clean.

(It'll get colder and wetter as the winter wears on, but I'm trying to, like, get prepared for once.)

Kek. No it's legit. If you do it, have high quality paper towels or a rag on hand that won't leave bits of paper or fiber and wipe away any starch lines the potato leaves. It dries clear and helps prevent condensation, similar to Rain-X.
 
I've used one of those aluminum space blankets to cover up my windshield. It won't mold, is easy to fit into place, and can be stored very easily.

Oh, this sounds clever. Where I work, a hobo might take it, but I'll try it.

Works amazing, you never have frosted windows ever.
