There could be harmful residue on the skin of the fresh fruits and vegetables and it is very important to get rid of them before consuming them. I like to soak my fresh produce in water mixed with veggie wash. You can also use a mix of 1 tbsp baking soda and 1/4 cup white vinegar in place of veggie wash to soak the fresh fruits and veggies. Fill a large tub with water. Add a cup of veggie wash or the baking soda and vinegar to it. Soak the fresh produce in the mixture for 30 minutes. Then rinse well and use.
