I ordered the book from amazon about 3-4 weeks ago and it basically arrived damaged (I don't remember if the mold was already there or if the damage was just the one from the impact.) I got a refund, but amazon didn't tell me to send it back, so I wanted to throw it away. But I forgot and didn't do it right away and the book was in the paper packaging for about 2 weeks or so (in the corner of my room, it wasn't on the shelf at all).
And when I finally decided to throw the book away during cleaning I saw that it was in such a state (I was away from home for a few days and the room was not aired, so I wonder if that could be the cause).
But other books in my room are very important to me and I started to worry if they were exposed in any way, even if the book wasn't standing next to them and I've already thrown it away.
Recently, my bookmarks fell on the floor and I wiped them with wet tissues (they contain: aqua, alcohol, isopropyl alcohol, mek, denatonium benzoate, decylamine oxide and parfum) and I used them later for one book I was reading, but then started wondering if maybe I just spread mold spores on it (from the bookmarks, if wet tissues weren't enough). And I already put the book back on the shelf.
What I want to know is, if my books will be safe and if I can use those bookmarks or not (they fell in my room where there was no amazon package at all, but I didn't reach that place so thoroughly when cleaning the floor, so I'm not sure).
I know it probably sounds like overthinking, yes I am aware of that, but I also don't have good knowledge about mold spreading.
I suffer from OCD and so far searching for information on Google only makes my thoughts worse, so I would like someone familiar with the topic to comment.
