Does hand sanitizer work as well as soap?
Last updated September 3, 2026.
No - the CDC is unambiguous: soap and water is the best way to remove germs in most situations; 60%+ alcohol sanitizer is the backup when no sink exists. Sanitizer kills but does not remove - dirt, grease, and dead germs stay on; it underperforms on dirty hands; and norovirus, the stomach-bug champion, shrugs off alcohol, which is why CDC norovirus guidance says soap and water, not sanitizer alone. One honest point for sanitizer: a backup you actually use beats a sink you skip. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.
What to do
- Sink first: soap plus 20 seconds of friction beats every gel.
- Sanitizer for transit: check the label for 60%+ alcohol.
- Stomach-bug season = soap only: norovirus ignores alcohol.
- Get seen if: frequent stomach or respiratory bugs keep cycling through your household - hygiene habits are worth reviewing with a clinician.
