put a tiny bit of toothpaste into a small cup, mix in one teaspoon baking soda 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.
my mom does this-Cleaning fruit - fill sink with water, add 1 C. vinegar, mix. Add all fruit and soak for 10 minutes. Water will be dirty and fruit will sparkle with no wax or dirty film. Great for Berries too--keeps them from molding. I do this with strawberries and they last for weeks!
