To remove nail polish from carpets, nail polish remover will work but you need to USE CAUTION because it can also remove dye from your carpet or upholstery. On light colored carpet it might not be noticeable but on darker colors. TEST FIRST!
Otherwise, a little nail polish will be the least of your worries. How about having to replace a whole roomful of carpet or trying to match the carpet color to dye one patch? For carpet, always test any kind of chemical stain remover/cleaner in an out of the way place like a corner.
Under a cushion might be a good spot for upholstery. More.
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.
