How does nail polish remove nail polish?

It doesnt. It jsut covers up the previous color Correction: putting nail polish on old nail polish then quickly wipeing it of takes it off because the new nail polish grabs the old like insta glue and takes the old when you wipe it off.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
