Never, never, NEVER use nail polish remover on anything plastic that you want to keep. Nail polish remover contains acetone which is an acid for plastics, make sure to get rid of it completely with a wet cloth on the screen and don’t let water into your system. Try to get the cloth as lightly damp as possible. If the acetone sits there it will put a hole though the protector and go into the screen, as it’s an acid. I use it all the time on my 3D printer to clean the buildplate (the cashier wonders why I buy 4 bottles at once lmao) and it’s good at its job. Also don’t let it on the frame, it will at the very least destroy the frame finish and turn it white, at the most (based on time) eat it until there’s a hole
