What is the Correct Order to Wash Your Hands? A Step-by-Step Guide to Effective Germ Removal

Washing your hands is one of the simplest and most effective ways to prevent the spread of germs and illnesses. But are you doing it right? Following a specific order of steps ensures you’re not just rinsing away soap, but truly eradicating harmful bacteria and viruses. This detailed guide will walk you through the scientifically proven method for squeaky-clean hands.

Why the Specific Order Matters

The order of handwashing isn't just a suggestion; it’s a protocol designed to maximize germ removal. Each step builds upon the last, creating friction and using soap’s chemical properties to dislodge and wash away microbes. Skipping steps or performing them out of order can leave unseen contaminants on your skin, defeating the purpose of the entire exercise.

The 6 Essential Steps to Proper Handwashing

The Centers for Disease Control and Prevention (CDC) outlines a clear, concise, and effective method for washing your hands. Let's break it down, step-by-step:

Wet your hands: Begin by turning on the faucet and thoroughly wetting your hands with clean, running water. This can be either warm or cold water – the temperature doesn't significantly impact germ removal, but warm water can be more comfortable.
Apply soap: Apply enough liquid, bar, or foaming hand soap to cover all surfaces of your hands. Don't be shy with the soap; a good lather is crucial for lifting dirt and germs.
Lather and scrub: Rub your hands together vigorously, making sure to lather all surfaces. This includes the backs of your hands, between your fingers, and under your nails. Scrub for at least 20 seconds. This is the equivalent of singing "Happy Birthday" twice.
- Scrub the palms of your hands together.
- Rub the back of each hand with your palm, interlacing your fingers.
- Rub your palms together with your fingers interlaced.
- Rub the backs of your fingers to your opposing palms with fingers interlocked.
- Rub each thumb by rotating it in the palm of your opposing hand.
- Rub the tips of your fingers by rotating them in the palm of your opposing hand.
Rinse thoroughly: Turn the faucet back on if you turned it off. Rinse your hands well under clean, running water, making sure to wash away all the soap.
Dry your hands: Dry your hands completely using a clean towel or airdryer. Damp hands can still harbor germs, so ensure they are thoroughly dry.
Turn off the faucet: If you used a paper towel to turn off the faucet, use that same towel to avoid recontaminating your hands. Otherwise, use a clean towel.

When Should You Wash Your Hands?

While it's beneficial to wash your hands frequently, there are specific times when it’s absolutely critical:

Before, during, and after preparing food
Before eating food
Before and after caring for someone who is sick
Before and after treating a cut or wound
After using the toilet
After changing diapers or cleaning up a child who has used the toilet
After blowing your nose, coughing, or sneezing
After touching an animal, animal feed, or animal waste
After handling pet food or pet treats
After touching garbage
When your hands are visibly dirty

The 20-second scrubbing rule is a key component. It ensures that soap has enough time to break down and lift away germs effectively. Don’t rush this vital step!

What About Hand Sanitizer?

When soap and water are not readily available, an alcohol-based hand sanitizer containing at least 60% alcohol can be a good alternative. However, it’s important to remember that hand sanitizers do not work well when hands are visibly greasy or dirty. In such cases, washing with soap and water is always the superior option. If you use hand sanitizer, apply enough to cover the entire surface of your hands and rub them together until they are dry.

Frequently Asked Questions (FAQ)

How long should I scrub my hands?

You should scrub your hands for at least 20 seconds. A good way to time this is to sing the "Happy Birthday" song twice.

Why do I need to use soap?

Soap is essential because it helps lift dirt and germs from your skin, making them easier to wash away. Soap molecules have a part that attracts water and a part that attracts grease and dirt, effectively encapsulating and removing them when rinsed.

What if the water is cold? Does it matter?

No, the temperature of the water does not significantly impact the effectiveness of handwashing. Both warm and cold water can be used. The key is the friction from scrubbing and the action of the soap.

Why is drying my hands important?

Drying your hands completely is crucial because germs can transfer more easily from wet surfaces. Damp hands provide a more hospitable environment for microbes to linger and spread.
