When completing hand rubbing, how long should you rub your hands for?

• A. 5 seconds
• B. Until they dry or at least 15 seconds (whichever comes second)
• C. 2 minutes
• D. 20 seconds

Answer: (B)

Rubbing with an alcohol-based hand sanitizer should last long enough to cover all surfaces and allow the product to dry. The best guidance combines both ideas: rub for at least 15 seconds to ensure sufficient contact time, and continue until the sanitizer has dried on the hands. This ensures even coverage on palms, backs of the hands, between fingers, and under the nails, and that the antimicrobial action can take effect. Shorter times may not provide adequate coverage, while waiting for drying ensures the product remains on the skin long enough to work.
