When Hand Sanitizer Beats Soap (and When It Doesn't)

They're not interchangeable — and one has real limits.

Sanitizer and soap both "clean" your hands, but they work differently — and knowing when to use which actually matters.

Soap removes, sanitizer kills

Soap lifts germs, dirt, and oils off your skin and rinses them down the drain. Sanitizer kills many germs in place but removes nothing — so on visibly dirty or greasy hands, it barely works.

The gaps

Alcohol sanitizer (look for 60%+) is great in a pinch, but it's weaker against certain bugs like norovirus and doesn't clear off grime or chemicals. It's a backup, not an upgrade.

The move

Soap and water when you can — especially before eating and after the bathroom. Sanitizer when there's no sink. And skip "antibacterial" soap; plain soap works just as well without the extras.
