Vinegar can work to remove pesticides from your vegetables but I would use Apple Cider Vinegar to remove pesticides from the vegetables instead as Apple Cider Vinegar works much better at removing Pesticides and bacteria from Vegetables.
Apple Cider Vinegar contains antibacterial properties in it which can kill off bacteria as well as get rid of pesticide residue from the vegetables.
Fill a bowl with water enough to cover the vegetables and then add a cup of Apple Cider Vinegar to the bowl of water and then place the vegetables into the Apple Cider Vinegar and let them soak for 15 to 20 minutes and then remove them and rinse the vegetable and use a vegetable brush to clean the pesticide residue from the vegetables and then rinse them again in cold water.
