As a refresher, the book I bought had a large sticker on the back that I needed to get off.
Here is a picture again:
I was planning on getting nail polish remover, but that was more of a backup plan. So, rather than nail polish remover, I went with Goo Gone and a plastic putty knife. The Goo Gone is a citrus and oil based cleaner. What I bought came in a spray bottle so I sprayed a small portion of the sticker and waited a few minutes and was able to easily peel it off. It took about 30 minutes of spraying a little of the page, gently peeling, and then wiping the Goo Gone off.
It looked a bit more used, but I was able to send it off to Amazon. Here’s hoping!
