Post it note stain on wall

Long time lurker, first time poster. I have an interesting cleaning issue. In order to learn more nouns in my second language, I started using sticky notes to “label” random objects in that language.

What you’re looking at is the spot my “towel” sticky once sat. I guess the steaming up of my shower caused this. I’m gonna see if I can do anything to get it out… wish me luck…

Second photo is what 91% alcohol got me. But its currently having diminishing rewards. Any suggestions? I think i might have to repaint.
