What is the recommended water temperature for effective handwashing?

The recommended water temperature for effective handwashing is 100°F. Using water at this temperature is comfortable for most people, which encourages thorough cleaning without causing skin irritation. This temperature ensures that the soap can effectively emulsify and lift away dirt, grease, and bacteria from the skin.

Furthermore, warm water enhances the lathering ability of soap, making it easier to wash away contaminants. While higher temperatures may seem more effective, they can lead to discomfort and discourage people from washing their hands properly and for the recommended duration. Keeping handwashing practices comfortable and effective is essential for maintaining good hygiene in any foodservice setting, including Starbucks.
