Washing your vegetables in plain water can remove at least 80 percent of the residue of the pesticides that are used on vegetables.
Washing your Vegetables in Salt water or even Apple Cider Vinegar can help remove Pesticides as well as bacteria from the Vegetables.
Soak the Vegetables in a bowl of water with some apple cider vinegar for 15 to 20 minutes and then lightly scrub them to remove the pesticides and residue from them.
