The science of loading a dishwasher

Daily Mail, UK - Engineers at the University of Birmingham tracked water movement inside empty and fully loaded household dishwashers using radioactive isotopes

They found the water was most powerful close to the jets on the rotating arms and about 60cm (23 inches) up from the bottom of the appliance . This is the best place for crockery caked with stubborn carbohydrate food

Dishes packed close to the walls on the lower shelf are allowed to soak in detergent for longer making them ideal for cleaning protein like egg yolk

The researchers say overloading stops water to reaching all the surfaces
