* Soap: This is the most important ingredient. Soap helps to lift and remove dirt, grease, and microbes from the skin.
* Water: Running water is needed to wet the hands, lather the soap, and rinse away the dirt and soap.
* Towel: A clean towel is used to dry the hands after washing. Using a clean towel prevents recontamination.
Optional but beneficial items:
* Hand sanitizer: An alcohol-based hand sanitizer (at least 60% alcohol) can be used when soap and water are not available.
* Hand lotion: Hand washing can dry out the skin, so lotion can help to moisturize and prevent cracking.
* Nail brush: A nail brush can help to clean under the fingernails where dirt and germs can accumulate.
* Warm Water: While not essential, warm water can help to dissolve soap and remove grease more effectively than cold water.
* Touchless Soap Dispenser/Faucet/Towel Dispenser: Reduces the risk of recontaminating your hands after washing.
The most important thing is to use soap and water properly and to wash your hands for at least 20 seconds.
