you can get these big carpet cleaners and they should do the trick! (trust me i am a teen and have done it many times be4) i think u can rent them at any drycleaning place!
I tried this trick, it's easy. I know it sounds odd---but try it. Coat the area of your nails that has nail polish onn with another type of nail polish. Leave the polish on for about 10 seconds, then...
The main ingredient in nail polish is acetone and in some cases acetate. The acetone dissolves the nail polish; liquifying it. This makes it easy for it to wipe off with a cotton ball or tissue.
