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.
How to clean your garbage disposal. Start by running hot water through your garbage disposal for a minute. Pour about 1/4 c. baking soda into the drain. Flip the garbage disposal on for 2 seconds, just to whirl the baking soda inside, and then leave it alone for 10-15 minutes. Follow with 1 c. of vinegar. Watch the bubbles erupt out of your drain. (Yay!) Rinse through one last time with very hot water and run your garbage disposal for 5 seconds.
