The best way of loading a dishwasher, according to Consumer Reports, involves placing cups, glasses and small bowls in the top rack. Forks and spoons should be placed facing down, while knives should be placed with handles sticking up.
Plates and serving bowls, and other large items should be placed on the bottom shelf. Over-sized items should be placed towards the sides and back, so they don’t block the water and detergent.
