Vinegar
Pros
- Kills approximately 98% of surface bacteria on produce

When to Use Baking Soda
Use a baking soda soak for produce where pesticide removal is the priority: conventional (non-organic) apples, grapes, strawberries, peppers, and other items on the Environmental Working Group's Dirty Dozen list.
When to Use Vinegar
Use a vinegar wash for quick-rinsing of leafy greens, herbs, and delicate berries. A solution of 1 part vinegar to 3 parts water works well for a 1-2 minute soak followed by a water rinse.
