Is temperature of hot water effective in sanitizing?
Temperature: The temperature of the solution is crucial. The water must be warm enough to increase the activity of the solution, but not so hot that it increases the evaporation of the sanitizer. Generally temperatures between 75°F and 120°F allow sanitizers to work properly.
At what temperature does water kill bacteria?
Too Hot for Hand-Washing At higher elevations, water should be boiled for 3 minutes. 2 So that’s 212 degrees F (at sea level) to reliably kill bacteria and pathogens to make water potable.17 jul. 2020
At what temperature does water sterilize?
Water temperature must be at least 180°F, but not greater than 200°F. At temperatures greater than 200°F, water vaporizes into steam before sanitization can occur. It is important to note that the surface temperature of the object being sanitized must be at 160°F for a long enough time to kill the bacteria.
Does hot or cold water kill germs?

What bacteria can survive in hot water?
Some bacteria can survive at very high temperatures. These types of bacteria are called thermopiles, which means “heat loving.” Thermophiles are harmless to humans and grow best at temperatures between 113 to 176°F (45 to 80°C). They’re often found in hot springs and in hydrothermal vents deep in the ocean.16 sep. 2020

Will 120 degree water kill bacteria?
A study by the American Society of Sanitary Engineering showed that the bacteria cease to multiply when water temperature reaches 120 degrees. They are not destroyed at that temperature, however, and can survive to be conveyed to an outlet such as a shower head or faucet.
