Toothpaste Stain Removal - Certain nail polishes can really stain your nails in a way that cannot be cleaned by acetone. An easy way to combat this is to massage whitening toothpaste onto your nails, scrub them and rinse off (repeat if necessary).
How to get white toenails: mix a small amount of baking soda and hydrogen peroxide together. Make into a paste. Get a tooth brush and scrub the paste onto your toenails. Then soak your toenails in the paste. Let them sit for 5-10 min. Then rinse off toes.
