Rubbing the outer layer of produce under running water is the best way to remove pesticides. It also lowers bacterial count by tenfold. If your fruits or vegetables are hardy enough, use light friction when you rub. Some produce, however, like apples, peppers, cucumbers and tomatoes have an edible wax coating, which protects them from bruising but can also trap pesticides and dirt underneath. For these items, a mild soap and water mix or ready-made produce wash can help remove the wax and trapped dirt.
