Wash it
You need to be carful with carpet, and take into consideration what type of carpet you have. Some people have ended up with permanent stains because they have used something which has made it worse. Non acetone nail polish remover is good. Have you trid an acetone nail polish remover? Gentle rubbing of the stain with shaving cream.
Carpet cleaner usually works for me! Just put some on the nail polish and rub!
It depends on what item the nail polish is staining. It is nearly impossible to remove nail polish from fabrics/carpet/tablecloths because the nail polish remover will bleach and damage the fabric before it will remove all the color of the polish. Commercial stain remover products will not be effective on nail polish as it is paint based. If it was spilled on glass then it is safe to use nail polish remover. On wood furniture it will also remove the varnish and wood stain along with the polish so that isn't good either. In other words, your parents are going to "notice" wherever you spilled the polish.
NO, but Goof Off might.
