Leftover Lemons for Nail BrighteningAfter using lemons in drinks and recipes, I store them in a container in the fridge to use when my nails need a bit of a pick-me-up. Using nail polishes can leave stains on your fingernails, even with a light base coat. With clean fingers and nails, dip your fingertips into the lemons and twist. The alpha-hydroxy acid in the lemon will brighten your nail fibers and break down any other grime in your nails. Rinse with water, dry, and apply a hand lotion or oil. Your nails will look so fresh!
