Does A Dishwasher Get Hot Enough To Kill Bacteria?

The dishwasher is effective at disinfecting dishes and killing bacteria, as the enzymes in the dish soap combined with boiling water are effective in killing germs. To sanitize dishes, you must first wash the dishes and then soak them in a disinfectant solution to kill bacteria. During a normal wash cycle, the water temperature is between 140 and 145 degrees, and with a disinfectant rinse, the temperature reaches at least 150 degrees so that the water circulates in the dishwasher and kills bacteria present on plates and glasses.

Most dishwashers offer specific wash settings, and when this cycle is selected, the washing machine absorbs hot water and heats it up even more. This is possible thanks to the electrical resistance, which does most of the hard work and allows the inside of the dishwasher to bring the water to a higher temperature and resist the added heat.

While hot water does not kill many bacteria, it helps wash dishes and clothes, thereby ridding them of potential bacteria hosts. Washing dishes with hot water kills germs, although the temperature must be above 65 ° C for deep and effective cleaning.

This is good news for anyone with a dishwasher that operates in temperatures between 130 and 170 degrees Fahrenheit. But most people can’t stand water temperatures above 104 degrees, which means those of us who get tired of washing up are more likely to leave some bacteria on our plates. Dishwashers use a lot of water to wash dishes, even relying on hot water production to achieve a high wash temperature. Consequently, dishwashers are more hygienic in terms of the equipment used to wash the dishes.

Dishwashers are great at removing food waste and dirt from your plates and cutlery, leaving them safe for next use. However, skipping them in the dishwasher doesn’t mean your dishes have been sterilized – sterilization requires professional-quality equipment – but disinfecting pots, pans, plates and cutlery in the dishwasher is all that is needed for safe cooking. food. As long as your dishwasher heats up to the right temperature, you are guaranteed clean and sanitized dishes.

Most dishwashers have a separate disinfection cleaning cycle or special settings. After reaching the ideal temperature, the dishwasher will circulate hot water throughout the equipment to extend the cycle time, just like the disinfection function. The higher temperature used in the dishwasher disinfection cycle will always work.

Dishwasher disinfection cycles use warmer water and longer wash times to kill 99.999% of foodborne bacteria. The National Sanitation Foundation requires them to heat water to at least 150 degrees Fahrenheit, although some dishwashers can go further. Basically, dishwashers can use incredibly hot water and much stronger detergents than regular dish soap to get the job done. Like hand soap, dish soap doesn’t kill bacteria; it pulls them away from surfaces so they can be washed off with water.

It does not physically kill viruses, but like hand soap, it removes germs and bacteria from cooking and food preparation surfaces so they can be easily washed off with water. If you have a dishwasher with a disinfecting function, use a continuous hot water rinse to kill germs and bacteria.
