Scrub nails with toothpaste using a nail brush or even an old toothbrush. A whitening toothpaste may even work better. The toothpaste will remove surface stains and give your nail a nice shine, too.*LEMON. Grab a lemon and squeeze a few drops onto each nail and rub for about 30 seconds and rinse.BUFF. Use a buffer and gently buff the nail surface. Wash hands with soap and water and then apply a moisturizing hand lotion. Just be careful not to buff too much. Small amounts of buffing can remove stains, smooth ridges, and promote nail growth but too much will weaken nails and lead to breaking.
