Applying nail polish too often stains the nails. The discolored nails, although harmless, prompt you to paint your nails all the time. However, whitening stained nails is easy. It is always advisable to whiten the nails after removing the nail polish and before manicure. One of the easiest ways to whiten the nails is to scrub the stained nails with baking soda paste. Adding few drops of lemon juice to the baking soda paste helps to remove stubborn polish stains from the nails. If both these aforementioned whitening recipes fail to remove the paint stain, add a teaspoon of hydrogen peroxide to the baking soda paste.
