* Don't use cold water: Warm or tepid water is more effective at removing germs and bacteria than cold water.
* Don't skip the soap: Soap is essential for lifting germs from your skin. Just rinsing with water isn't enough.
* Don't rush: You need to wash your hands for at least 20 seconds (about the time it takes to sing "Happy Birthday" twice). Rushing through the process leaves germs behind.
* Don't neglect areas: Make sure you're washing all surfaces of your hands, including:
* Palms
* Backs of hands
* Between fingers
* Under fingernails
* Wrists
* Don't forget to dry: Wet hands spread germs more easily than dry hands. Dry your hands thoroughly with a clean towel or air dryer.
* Don't turn off the faucet with your bare hands: If you used your hands to turn on the faucet, they might be contaminated again. Use a paper towel to turn off the faucet, if possible.
* Don't use a dirty towel: Using a dirty or damp towel to dry your hands can recontaminate them.
* Don't touch your face while washing: Avoid touching your face (eyes, nose, mouth) during handwashing, as this can transfer germs.
* Don't use hand sanitizer as a replacement for soap and water when hands are visibly dirty: Hand sanitizer is great when soap and water aren't available, but it's less effective if your hands are visibly soiled.
* Don't use public towels (if you can avoid it). Public towels can harbor a lot of bacteria. If possible, use a paper towel or let your hands air dry.
By avoiding these mistakes, you can make sure you are washing your hands effectively and protecting yourself and others from illness.
