  5. How.com.vn English: Watermark How.com.vn to Wash Your Hands
    Put one hand on top of the other so both of your palms face down. Put the fingers from your top hand in between the ones on your bottom hand. Move your hands up and down along the lengths of your fingers to scrub them. Then interlace your fingers with your palms together and repeat the process.

  7. How.com.vn English: Watermark How.com.vn to Wash Your Hands

    • If you’re using reusable hand towels, wash them at least every 2 or 3 days so germs don’t build up.

Using Hand Sanitizer

Download Article
  1. How.com.vn English: Step 1 Decide if hand sanitizer is appropriate.
    There are some situations where you can use alcohol-based hand sanitizer instead of using soap and water to wash your hands. However, you may want to take a moment to evaluate the situation. Some things you should consider include:[17]
    • Whether or not your hands are visibly dirty. If you can see the dirt or grease on your hands, then use soap and water to clean them.
    • What you have on your hands. Alcohol-based hand sanitizer will not eliminate all of the germs on your hands and it will not remove certain substances, such as pesticides and heavy metals. In these situations, opt for soap and water.
    • The availability of water. If you don’t have running water, then use alcohol-based hand sanitizer since it’s better than leaving your hands dirty. However, if you have access to soap and running water, wash your hands instead.
  2. How.com.vn English: Step 2 Apply a coin-sized amount of hand sanitizer to one hand.
    Opt for a hand sanitizer that has at least 60% alcohol so it’s more effective at killing harmful bacteria. Push down on the pump to squirt a coin-sized amount of the sanitizer directly into your palm.[18]
    • You can also use alcohol cleaning wipes if you have them.
  3. How.com.vn English: Watermark How.com.vn to Wash Your Hands
    Rub your hands together for about 20 seconds, and move the hand sanitizer around them as if you are washing your hands. Interlace your fingers to clean between them and rub your palms with your fingertips to get underneath your nails. Keep moving your hands around until they feel dry.[19]

      Article SummaryX

      Washing your hands can help protect yourself and others from getting sick. To wash your hands properly, start by wetting your hands with clean, running water. Then, apply soap to your hands and rub them together to form a lather. Rub your palms, the backs of your hands, in between your fingers, and under your nails. Keep scrubbing for at least 20 seconds, or the amount of time it takes to hum the “Happy Birthday” song twice. Finally, rinse your hands off under clean, running water and dry them with a clean towel. Use hand sanitizer to wash your hands if you don’t have access to soap and water. However, according to the Centers for Disease Control and Prevention, hand sanitizer isn’t as effective at killing germs as soap and water, so use soap and water whenever possible. Always wash your hands before and after preparing food, before eating, after using the bathroom, and after sneezing, coughing, or blowing your nose. You should also wash your hands before and after caring for a sick person, or after touching an animal, animal feed, or animal waste. If you want to learn how to disinfect your hands with hand sanitizer, keep reading the article!
