Yes! getting a nailpolish stain can be removed by first dabbing
the carpet with a non-acetone nailpolish remover. IF that does not
completely remove the stain, then spray some Windex on the stain
and rub with a clothe.

doesn't have a special chemical inside it to remove nailpolish. I
don't know what the chemical is called, but you can always go to
the nail polish store or go to CVS to find nailpolish remove
