How to Clean and Disinfect High-Touch Surfaces Properly

In today's world, cleanliness and hygiene have become increasingly important. With the rapid spread of infectious diseases, it has become essential to understand how to properly clean and disinfect high-touch surfaces to protect ourselves and others from harmful pathogens. High-touch surfaces, which include objects and areas frequently touched by hands, can harbor bacteria, viruses, and other harmful microorganisms that may contribute to illness.

Understanding the importance of high-touch surface cleaning, the proper techniques, and the right products to use is crucial for maintaining a healthy environment, whether at home, at work, or in public spaces. This article will provide an in-depth look at the process of cleaning and disinfecting high-touch surfaces properly, focusing on the importance of hygiene, best practices, and practical steps to ensure thorough cleaning.

The Importance of Cleaning and Disinfecting High-Touch Surfaces

High-touch surfaces, such as door handles, light switches, remote controls, keyboards, faucets, and smartphones, are constantly exposed to human contact. Since people often touch these surfaces without thinking about it, they can accumulate a wide range of germs and viruses. These germs can spread through direct contact with the surface or indirectly through objects like clothing or food.

The importance of cleaning and disinfecting high-touch surfaces lies in reducing the risk of transmission of diseases, especially those caused by bacteria, viruses, and fungi. For example, the coronavirus (COVID-19) pandemic highlighted how quickly viruses can spread from surface to surface. In fact, high-touch surfaces in shared spaces like offices, schools, and hospitals are particularly susceptible to contamination.

By adopting effective cleaning and disinfection practices, we can minimize the presence of harmful microorganisms and reduce the risk of illness. This is especially important in homes with children, elderly individuals, or people with weakened immune systems.

What Are High-Touch Surfaces?

High-touch surfaces are those that people frequently come into contact with throughout their day-to-day activities. These surfaces are particularly important because they act as potential transmission points for viruses, bacteria, and other pathogens. Some common high-touch surfaces in homes and workplaces include:

• Door handles and knobs: Common in almost every room and area of the house.
• Light switches: Used multiple times a day in every part of the house.
• Faucet handles: Found in kitchens, bathrooms, and laundry rooms.
• Remote controls: Typically found in living rooms and bedrooms.
• Smartphones, tablets, and laptops: Personal devices touched multiple times a day.
• Countertops and tabletops: Often used for meal preparation, studying, or working.
• Toilet handles and flush buttons: Frequently touched in bathrooms.
• Elevator buttons: Common in public places and shared buildings.
• Railings and handrails: Found on stairs, walkways, and escalators in public spaces.

Other surfaces that may be high-touch include keys, shopping carts, cash registers, gym equipment, and more. Since these surfaces are touched frequently by many individuals, they provide an ideal environment for germs to thrive and spread.

The Difference Between Cleaning, Disinfecting, and Sanitizing

Before delving into the specifics of how to clean and disinfect high-touch surfaces, it's important to understand the difference between cleaning, disinfecting, and sanitizing. While these terms are often used interchangeably, they have distinct meanings in the context of hygiene and disease prevention.

1. Cleaning

Cleaning involves the removal of dirt, dust, grime, and visible debris from a surface. This is typically done with soap or detergent and water. Cleaning is important because it removes the physical particles and organic matter that can harbor germs. However, cleaning alone does not eliminate germs or kill bacteria and viruses.

2. Disinfecting

Disinfecting is a more thorough process that uses chemicals or antimicrobial products to kill harmful pathogens on surfaces. Disinfectants are designed to target specific types of microorganisms, such as bacteria and viruses, by destroying their cells. To disinfect effectively, it's important to follow the instructions on the product label, as some disinfectants need to remain on surfaces for a certain period to be effective.

3. Sanitizing

Sanitizing refers to reducing the number of germs on a surface to a safe level, as determined by public health standards. Sanitizers are typically used on surfaces like food contact areas (such as kitchen counters) to ensure they are free from harmful microorganisms. Sanitizing is less intensive than disinfecting, and it is often used when cleaning and disinfecting are not necessary.

Step-by-Step Guide to Properly Clean and Disinfect High-Touch Surfaces

Now that we understand the importance of cleaning and disinfecting high-touch surfaces and the difference between cleaning, disinfecting, and sanitizing, let's break down the proper steps to ensure these surfaces are effectively cleaned and disinfected.

Step 1: Gather the Necessary Supplies

To clean and disinfect high-touch surfaces properly, you'll need the right tools and products. Here is a list of essential supplies:

• Cleaning cloths or paper towels: Microfiber cloths are ideal for cleaning, as they trap dirt and debris.
• Soap or detergent: Used for cleaning surfaces and removing dirt.
• Disinfectant: Look for EPA-approved disinfectants or those specifically labeled as effective against viruses, bacteria, and other pathogens.
• Gloves: Wear disposable gloves to prevent cross-contamination.
• Spray bottles: Use spray bottles to apply cleaning and disinfecting products effectively.
• Trash bags: Use to dispose of any paper towels or wipes used during cleaning.

Make sure the disinfectant you choose is suitable for the specific surface you're cleaning. For example, harsh chemicals may damage wood surfaces, while gentler products may be needed for electronics.

Step 2: Clean the Surface

Before disinfecting, it's important to clean the surface to remove dirt, grime, and other visible debris. Cleaning with soap and water helps to eliminate organic matter, which can interfere with the effectiveness of the disinfectant.

1. Apply soap and water: Use a damp cloth or sponge with a small amount of soap or detergent and wipe the surface thoroughly. Focus on areas that may have visible dirt or stains.
2. Remove dirt and debris: Pay attention to corners and crevices where dust and dirt can accumulate. This is especially important on surfaces like keyboards or remote controls.
3. Dry the surface: After cleaning, use a dry cloth or paper towel to wipe down the surface to remove excess moisture. Some surfaces may need to dry completely before moving on to the disinfection step.

Step 3: Disinfect the Surface

Once the surface has been cleaned, it's time to disinfect. Disinfecting involves using chemicals or antimicrobial agents to kill harmful microorganisms on the surface.

1. Choose the right disinfectant: Make sure the disinfectant is effective against the types of germs you're trying to kill. Look for products with labels that mention killing viruses, bacteria, and fungi. The disinfectant should also be EPA-approved for use against pathogens like the flu virus or coronavirus.
2. Follow product instructions: Always read and follow the instructions on the disinfectant label. Some disinfectants need to remain on the surface for a certain amount of time (also known as "dwell time") to be effective.
3. Spray or wipe down the surface: Depending on the product you're using, spray the disinfectant directly onto the surface or apply it with a clean cloth or disinfecting wipe. Ensure the surface is covered evenly with the disinfectant.
4. Allow the disinfectant to sit: Let the disinfectant sit for the required amount of time (usually between 1 to 10 minutes) to ensure maximum effectiveness.
5. Wipe away excess disinfectant: After the disinfectant has had sufficient time to work, wipe away any excess using a clean, dry cloth or paper towel.

Step 4: Repeat Regularly

To maintain a hygienic environment, it's important to clean and disinfect high-touch surfaces regularly. In high-traffic areas or during flu season, cleaning and disinfecting should be done at least once a day or more often if necessary. Be mindful of shared spaces, such as offices or classrooms, and ensure that surfaces are cleaned and disinfected multiple times throughout the day.

For personal devices like smartphones and tablets, disinfect them regularly using alcohol-based wipes or a microfiber cloth lightly dampened with water and a small amount of mild soap. Always check your device manufacturer's instructions to avoid damaging your electronics.

Step 5: Practice Proper Hygiene After Cleaning

After cleaning and disinfecting high-touch surfaces, it's essential to practice good hygiene. Here are a few steps to take:

1. Dispose of used wipes and cloths: Dispose of any paper towels, wipes, or disposable gloves properly.
2. Wash your hands: Wash your hands thoroughly with soap and water for at least 20 seconds after handling cleaning materials. If soap and water are unavailable, use hand sanitizer with at least 60% alcohol.
3. Clean your cleaning tools: If you're using reusable cleaning cloths or sponges, make sure to wash them regularly to avoid cross-contamination.

Additional Tips for Disinfecting High-Touch Surfaces

• Use alcohol-based disinfectants: If you don't have access to an EPA-approved disinfectant, a solution containing at least 70% alcohol can be effective at killing viruses and bacteria.
