Yes, dishwashers are designed to sanitize dishes and utensils. Most modern dishwashers have a built-in heating element that heats the water to a high temperature during the wash cycle, typically around 140-145°F (60-65°C). This high temperature, combined with the use of detergent and the mechanical action of the dishwasher, helps to remove food particles, grease, and bacteria from the dishes.
Additionally, many dishwashers offer a sanitizing cycle or an option to boost the water temperature during the wash cycle. This further increases the water temperature to around 155-160°F (68-71°C) for a specific period, usually around 10 minutes or more. This extended exposure to high heat helps to kill bacteria, viruses, and other harmful microorganisms that may be present on the dishes.
It's important to note that not all dishwasher cycles have a sanitizing function. Some shorter or energy-saving cycles may not reach the same high temperatures needed for effective sanitization. Therefore, if sanitization is a concern, it is advisable to use a cycle specifically designed for that purpose or select the appropriate option if available.
To ensure proper sanitization, it's also important to scrape off excess food from dishes before placing them in the dishwasher and to load the dishwasher correctly, allowing water and detergent to reach all surfaces. Additionally, using a dishwasher detergent that is specifically formulated for sanitizing can help achieve better results.
Overall, when used correctly and with the appropriate settings, dishwashers are effective at sanitizing dishes and can help maintain good hygiene in the kitchen.
