酒精性乾洗手（Alcohol-based hand rub）是臨床上快速且有效的手部衛生方式。其殺菌機轉為透過酒精使蛋白質變性，進而殺滅病原體。為確保足夠的殺菌效果，必須使用足量的洗手液，並確保雙手每個表面（指縫、指尖、手心、手背）均被覆蓋，且必須摩擦至雙手完全乾燥，因為酒精揮發的過程即是殺菌過程的一部分。
When using an alcohol-based hand rub, sufficient product must be applied to cover all hand surfaces. Hands should be rubbed until completely dry, as the friction and evaporation process are essential for effective microbial reduction.
