I can provide you with some general information about dishwashers and their usage.
Modern dishwashers are designed to wash soiled dishes effectively without the need for prewashing. They use a combination of hot water, detergent, and powerful jets to remove food particles, grease, and stains from the dishes. Pre-rinsing or prewashing dishes before loading them into the dishwasher is generally unnecessary and can waste water and energy.
To get the best results from your dishwasher and save resources, you should scrape off large food debris from the dishes before loading them. However, it's not necessary to prewash the dishes with soap and water.
Dishwashers are also effective at sanitizing dishes. The high water temperatures and prolonged exposure to hot water during the wash cycle help kill germs and bacteria, leaving your dishes clean and sanitized.
For heavily soiled or baked-on dishes, some dishwashers have specific settings like "Heavy" or "Pots & Pans" that provide more intense cleaning cycles. If you encounter any particularly tough stains, you can also use dishwasher-safe cleaning agents like rinse aids or dishwasher cleaner to help maintain the dishwasher's performance.
Overall, dishwashers are convenient and efficient appliances that can handle most of your dishwashing needs without the need for prewashing, helping you save time, water, and energy.
