You can wash Vegetables in Apple Cider Vinegar or even just plain water.
Washing Vegetables and fruits in Apple Cider Vinegar or plain water will remove most if not all the pesticide residue as well as any other dirt or grime that may be on the fruits or vegetables.
Soak the fruits and vegetables in a bowl of water with or without the Apple Cider Vinegar and let them sit for 20 minutes and then use a vegetable brush to gently and lightly scrub the Vegetables and fruits to remove any residue.
