Washing Your Hands the RIGHT Way

Follow these steps every time.

  1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
  2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
  3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
  4. Rinse your hands well under clean, running water.
  5. Dry your hands using a clean towel or air dry them.

Here is a demonstration from the World Health Organization as to how to properly wash your hands: WHO: How to Handwash

Use Hand Sanitizer When You Can’t Use Soap and Water

Washing hands with soap and water is the BEST way to get rid of germs in most situations. However, if soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label.

Sanitizers can quickly reduce the number of germs on hands in many situations. However,

  • Sanitizers do not get rid of all types of germs.
  • Hand sanitizers may not be as effective when hands are visibly dirty or greasy.
  • Hand sanitizers might not remove harmful chemicals from hands like pesticides and heavy metals.

When possible, people should wash their hands with warm water and soap, as directed above.

How to use hand sanitizer

  • Apply the gel product to the palm of one hand (read the label to learn the correct amount).
  • Rub your hands together.
  • Rub the gel over all the surfaces of your hands and fingers until your hands are dry. This should take around 20 seconds.

Disinfecting Surfaces

Frequently touched surfaces, such as door knobs, light switches, phones, keyboards/computer screens, toilets, table tops, etc., should be cleaned often in order to prevent the spread of germs.

  • Wear disposable gloves when cleaning and disinfecting surfaces. Gloves should be discarded after each cleaning. If reusable gloves are used, those gloves should be dedicated for cleaning and disinfection of surfaces for COVID-19 and should not be used for other purposes. Consult the manufacturer’s instructions for cleaning and disinfection products used. Clean hands immediately after gloves are removed.
  • If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
  • For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
    • Diluted household bleach solutions can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
      • Prepare a bleach solution by mixing:
        • 5 tablespoons (1/3rd cup) bleach per gallon of water or
        • 4 teaspoons bleach per quart of water
    • Products with EPA-approved emerging viral pathogens are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).
  • For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces. After cleaning:
    • Launder items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely, or
    • Use products with the EPA-approved emerging viral pathogens claims that are suitable for porous surfaces.
Here are instructions for how to properly mix bleach and water for a disinfecting solution.
