Isopropyl and ethyl alcohol are different. Ethyl you can drink.
I do like ethanol for cleaning purposes, but difficult to get from a store as just good old ethanol plus a few things in small quantities.
Both work for sanitizing, I would have to look up the differences for deicing one would be better at lower temps. I find ethanol to be a bit nicer to work with. Denaturing just means throwing stuff into ethanol that prevent people from drinking it, nasty tasting stuff, toxic stuff, etc. Otherwise it's typically taxed, although not for lab use, hence the logging of what we used it for.
Amen.
But use it as a prop or an assist, not a crutch. I had a prof in library school who basically just read his transparencies as the whole lecture. I cringe at the thought of him with Powerpoint. Sadly, he is no longer with us. Terrible prof but not a bad guy otherwise.
It is what you stand on when you are on a ship!
