When it comes to washing fruits and vegetables in order to ensure that they are clean enough to eat, Janet Bond Brill, PhD, RDN, FAND, LDN, a nutrition and fitness expert, follows the US Food and Drug Administration’s recommendation and uses plain water to rinse them clean. This method eliminates 98% of the germs that may be present on these foods. Soaps, detergents and special fruit/vegetable washes are not necessary, so Dr. Bond Brill urges people not to waste money on them. You can scrub apples to remove the waxy finish if you prefer, but this, too, is not necessary.
