I use this recipe to clean the pesticides off my produce. It was featured on Oprah last year.
1 cup water
1 cup distilled white vinegar
1 Tbsp. baking soda
20 drops of grapefruit seed extract
Combine all ingredients in a large container. Then, transfer to a spray bottle with a pump. Spray mixture on produce, and rinse thoroughly after 5 to 10 minutes.
