A mixture of three parts water and one part white vinegar can be used to make an inexpensive wash for fruits and vegetables. Use a spray bottle filled with the mixture to clean smooth-surfaced fruits like apples and pears, then rinse under cold water. Clean berries and other delicate fruits in the mixture in a bowl and then rinse gently with cold water.
Wash fruits with inedible skins, such as oranges and melons, before cutting to remove any bacteria.
