A trick for removing dark nail polish stains

I recently read about an awesome French trick for cleaning the dark nail polish stains off of your fingernails. All you do is hold your nails in a dish of lemon juice mixed with a bit of water for a few minutes and the stains fade instantly. Cool, right?

I was a little skeptical that it would work, but when I tried it myself after using my darkest polishes several weeks in a row, it really did help! Lemon juice is apparently good for both whitening nails and strengthening them when used in an olive oil mixture.

This is a really helpful tip to learn going into spring because I like to transition from my dark shades to lighter, more pastel hues, and the light colors can a little dirty with dark stains behind them.

Have you ever tried this trick before? What beauty tricks do you swear by?
