Away!
I’m with @HiHoeSilver on this.
If you through warm/hot water on a windshield in the middle of a Midwest winter, the thermal shock will shatter your glass. Seen it when I was a teenager. A guy from Texas moved in next door and was making fun of me being a hick and scrapping my windshield. He said “this is how you get ice off of a windshield” as he threw a pan of warm water on his windshield only to get a loud boom as the windshield shattered.
I reached into my trunk and handed him my spare scrapper and told him to use it the next time after he gets his windshield replaced.
With dials set to 90 and fan on high, my dash vents are my scraper. Lol.
