I dissolve some baking soda into water and soak my veggies and fruits for about 10-15 minutes. I do this especially with grapes and strawberries. You will notice a big difference especially when you see how murky the water gets.

And baking soda is also great as a teeth whitener. Sprinkle some on your toothbrush and brush. Then rinse mouth with water. Do this everyday and you will have sparkling white teeth!
