What can I use to remove the stains?

Help! And although I stupidly left our Macbook on my desk and my little sister painted on it a little on the stickers (which are on my laptop) and wanted to do it, but it smeared itself afterwards and if my mother sees it, she'll kill me. How can I clean this up?

Ok i got it anyway thank you😅

With a cotton swab, first try very carefully with nail polish remover in one place, but take acetone-free. You can also test cooking oil, margarine, vodka, clear window glass, etc. Beforehand.
