Nail polish remover
Commercial nail polish removers are often loaded with chemicals and artificial scents. Switch to baking soda which can remove old nail polish and nail stains just as effectively. Mix 1 tablespoon of baking soda with 1 teaspoon of hydrogen peroxide in 1/2 cup water to create a dipping solution. Dip the nails in the solution for 3 minutes. The polish and stains should come off easily once you rinse.
