Clean, healthy looking toenails and fingernails are a sign of good grooming. Discoloured, yellow or ragged nails are not aesthetically pleasing. Toenails tend to yellow or darken easily as they are thicker than fingernails. One reason that they may have become discoloured is if you have been wearing dark-coloured nail polish on them. Another cause of toenail discolouration is due to foot fungus. Whatever the reason, bleach toenails to make them look clean and white.
Dampen a cotton ball with hydrogen peroxide. Rub the cotton ball underneath your toenails and across the top of them. Let the hydrogen peroxide dry. There is no need to wash them afterward.
Cut one lemon into small slices. Use one slice of lemon to rub on top and underneath your toenails on one foot. Use another slice of lemon and do the same thing on the other foot. If you have any cuts or hangnails, you may experience some stinging or pain. Wash feet with warm water when you're done.
Squeeze some whitening toothpaste onto a toothbrush. Make sure it's an old toothbrush, or one that you will not use again. Brush the toothpaste onto your toenails, just as you would your teeth. Brush underneath and on top. Do this daily for one week.
Do not get any of the whitening ingredients in your eyes.
