Okay, we'll settle the great debate. Here's the proper way to load a dishwasher:
Manufacturers advise that cutlery be loaded with the "business" end facing up, a.k.a. the end that touches food. The reason? Better water circulation. Facing the business-end down in the basket restricts water flow. However, sharp knives and utensils should always face down to help prevent injury when unloading the dishwasher. Care should be taken, of course, when removing these utensils from the basket.
Dishes and cookware should have exposed surfaces facing the spray arms. Knives and other cutlery with wooden handles are best washed by hand because over time, detergent can cause wood to become brittle and crack.
