How to wash your hands 1. Don’t use antibacterial soap (抗菌肥皂) –it does little extra good and can create “super-bugs (超级细菌)”. Regular soap will do. 2. Wash for 30 seconds with warm water and soap. You can keep track by singing “Happy Birthday” twice. 3. Be sure to get oft-neglected(经常忽视的)places: fingertips, between fingers (webbing), and under the nails. 4. How you dry your hands is up to you, but a hands-free dryer (干手器) is the best for both cleanliness and the environment. 5. Use a paper towel or your sleeve (袖子) to open the door when you are leaving. 6. Hand sanitizer (洗手液) is better than nothing.
