摘要

Forks up, knives down and be sure to pre-rinse. Or was it bowls down, knives up? And why do I need to rinse? Isn't that what the dishwasher is for? Deep mystery of the universe it is not, yet proper use of the dishwasher is an endless cause of domestic turmoil. We all have our kitchen quirks, whether reasoned or the result of years of habit. Now, finally, research provides definitive answers about which loading techniques just won't wash. The most common mistakes include the placement of bowls and tall items-and there are logical solutions to these dirty habits (see and in diagram, opposite). But settling more controversial dishwasher dilemmas requires a more technical approach. To study how water travels around a dishwasher, Raul Perez Mohedano at the University of Birmingham, UK, and his colleagues injected water with radioactive tracers. They could then use the tracers to follow the movement of the water when the dishwasher was put inside a scanner. The technique, called positron emission particle tracking, revealed water direction and velocity during a normal wash cycle. It turned up a few surprising insights.
