Use hydrogen peroxide and baking soda to clean your old cookie sheets. NO scrubbing!
How to get white toenails: mix a small amount of baking soda and hydrogen peroxide together. Make into a paste. Get a tooth brush and scrub the paste onto your toenails. Then soak your toenails in the paste. Let them sit for 5-10 min. Then rinse off toes.
Put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, and half a teaspoon water. Thoroughly mix then brush your teeth for two minutes. Remember to do it once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two. - And to think I almost shelled out $40 at the store for some whitening strips!
