The soap can be liquid or powdered and is squirted or placed into a designated area or receptacle. Another option is a small packet in which dish-washing soap is contained which can be thrown inside a dishwasher almost anywhere. Once loaded and with soap placed inside, users close and often lock the dishwasher before turning the device on.
Once on, the dishwasher takes in water from connected water hoses, heats the water to a high temperature, and then sprays the dishes with the hot water, rinsing them thoroughly. The process is repeated when the device adds the dish-washing soap or detergent to the hot water spray at high pressures, scouring stubborn stains, dirt and grease from dishes. A final step included on many dishwashers is a dish dryer, which leaves dishes warm, dry and free of spots. This last addition is awesome, as spotless dishes make it appear as if I hand-dried my own dishes before putting them away.
Remember to read the manufacturers instructions about the quantity of detergent. More is not better.
