Man oh man. We had to wrap our books in a type of thick, glossy paper. The books were borrowed from the school, so they expected them back in flawless condition. I kid you not, we even had to take sandpaper and file the 3 “paper sides” of the books to remove any stray pencil marks.
It was run by nuns, go figure.
If you don’t want to attempt cleaning it, you could just bury them outside?
Edit: Everyone didn’t like that.
Keep it on your shelf forever Wrap it in layers of newspaper and toss it out Just clean it. It’s glass. Use an ultrasonic
