Simple Rules of Hand Hygiene: When to Wash and When to Use Hand Sanitizer

“Wash your hands” is something we’ve all heard since childhood. After COVID-19, “sanitize your hands” became just as common. Both are essential for preventing germs — but they’re not the same. Knowing when to wash and when to sanitize is one of the simplest ways to protect your health and keep infections away.

Handwashing: The Best Deep Clean

Handwashing with soap and water is the most effective method of removing germs, dirt, oils, and chemicals from your hands. Soap molecules break down bacteria and lift them off the skin, and water rinses everything away.

Wash your hands whenever:

• Your hands look or feel dirty
• Before eating or handling food
• After using the restroom
• After touching garbage, cleaning supplies, or chemicals
• After touching animals
• After coughing, sneezing, or blowing your nose
• When caring for someone who is sick

How to wash properly:
Scrub for at least 20 seconds, including the backs of your hands, between your fingers, under your nails, and around your wrists.

Hand Sanitizer: The Quick Option When You Can’t Wash

When soap and water aren’t available, alcohol-based hand sanitizers (60% and above) are a fast and convenient alternative. They work by breaking down the proteins and outer layers of germs, killing them on contact. However, sanitizers do not remove dirt — they only disinfect.

Use hand sanitizer when:

• Entering public or crowded spaces
• After touching high-contact surfaces (elevator buttons, door handles, shopping carts)
• When soap and water aren’t available
• In healthcare or clinical environments

How to sanitize properly:
Apply enough sanitizer to cover your hands completely. Rub until fully dry — usually about 20 seconds.

Wash vs. Sanitize: The Simple Rule

• If your hands are visibly dirty → wash with soap and water.
• If they look clean but you need protection → use hand sanitizer.

Both work best when used together as part of your daily hygiene routine.
