Wedding-day white teeth! My dentist actually told me about this. Use a little toothpaste, mix in one teaspoon baking soda plus one teaspoon of hydrogen peroxide, 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.
Wash towels in Hot water and one cup of vinegar, then run a second time with 1/2 cup of baking soda. Do not add detergent. Leaves towels fresh and fluffy. Can also be used for bathing suits. I'm going to try it on my tee shirts that sat in the washer over night and smell bad after I wear them a few hours.
