The COVID-19 pandemic dramatically altered our lives, emphasizing the critical importance of hygiene and sanitation. While vaccines and treatments have become more readily available, the practices of cleaning and disinfection remain vital in mitigating the spread of the virus and other infectious diseases. This article provides detailed, practical, and up-to-date recommendations for cleaning and disinfection to protect yourself, your family, and your community during the ongoing pandemic and beyond.
Understanding the Difference: Cleaning vs. Disinfecting
It’s crucial to understand the distinct differences between cleaning and disinfecting. These terms are often used interchangeably, but they represent separate processes with different goals.
Cleaning involves removing visible dirt, debris, and impurities from surfaces using soap or detergent and water. This process doesn’t necessarily kill germs, but it lowers their numbers and the risk of spreading infection. Cleaning is a necessary first step before disinfecting.
Disinfecting, on the other hand, uses chemicals to kill germs on surfaces. This process doesn’t necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.
Cleaning removes dirt, while disinfecting kills germs. Both are important in preventing the spread of disease.
Key Principles of Effective Cleaning and Disinfection
Effective cleaning and disinfection go beyond simply wiping down surfaces. Several key principles should guide your efforts to maximize their impact.
Identify High-Touch Surfaces
Knowing which surfaces are touched most frequently is paramount. These are the surfaces most likely to harbor germs and require more frequent attention.
Examples of high-touch surfaces include doorknobs, light switches, countertops, tables, handles, faucets, toilets, keyboards, phones, and remote controls. In shared spaces, consider elevator buttons, shared workstations, and shared equipment.
Focus your cleaning and disinfection efforts on these high-touch areas to break the chain of transmission. Regularly assessing and updating your list of high-touch surfaces based on usage patterns is also helpful.
Choose the Right Products
Selecting appropriate cleaning and disinfecting products is crucial for effectiveness and safety. Not all products are created equal, and some may be more suitable for certain surfaces or situations than others.
For cleaning, use soap and water or a general-purpose cleaner. For disinfection, choose products that are EPA-registered disinfectants and have demonstrated effectiveness against SARS-CoV-2, the virus that causes COVID-19.
Always follow the manufacturer’s instructions for use, including dilution ratios, contact times, and safety precautions. Pay close attention to the product’s label and safety data sheet (SDS).
Follow Proper Procedures
Even with the right products, improper procedures can render cleaning and disinfection ineffective. Adhering to established guidelines is essential.
Begin by cleaning surfaces to remove visible dirt and debris. Then, apply the disinfectant according to the manufacturer’s instructions, ensuring adequate contact time. Contact time refers to the amount of time the disinfectant needs to remain wet on the surface to effectively kill germs.
Allow the surface to air dry whenever possible. If wiping is necessary, use a clean cloth or paper towel. Always wear appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling cleaning and disinfecting products.
Frequency Matters
How often you clean and disinfect depends on several factors, including the level of traffic, the potential for contamination, and the presence of individuals at higher risk for severe illness.

What is the difference between cleaning and disinfecting, and why are both important during the COVID-19 pandemic?
Cleaning refers to the removal of dirt, debris, and germs from surfaces. This is usually done with soap and water or a general-purpose cleaner. Cleaning doesn’t necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection. Think of it as a first step to reduce the overall germ load on surfaces.
Disinfecting, on the other hand, uses chemicals to kill germs on surfaces. This is done after cleaning. Disinfecting significantly reduces the risk of spreading infection because it actively destroys viruses and bacteria. Using both cleaning and disinfecting provides a comprehensive approach: cleaning removes visible dirt and some germs, while disinfecting kills any remaining germs, offering maximum protection.
Which disinfectants are effective against the virus that causes COVID-19?
The Environmental Protection Agency (EPA) maintains a list of disinfectants that meet their criteria for use against SARS-CoV-2, the virus that causes COVID-19. These disinfectants have been shown to effectively kill the virus on surfaces. Common active ingredients in these disinfectants include bleach, hydrogen peroxide, quaternary ammonium compounds (quats), and alcohol (at least 70% concentration).
Always check the EPA registration number on the product label to ensure it’s on the EPA’s List N. Carefully follow the manufacturer’s instructions for proper use, including contact time (the amount of time the disinfectant needs to remain on the surface to be effective). Ensure adequate ventilation during use and wear appropriate personal protective equipment (PPE) such as gloves.
How often should I clean and disinfect surfaces during the COVID-19 pandemic?
The frequency of cleaning and disinfecting depends on several factors, including the level of community transmission, the number of people using the space, and the frequency of touch. High-touch surfaces like doorknobs, light switches, countertops, faucets, and toilet handles should be cleaned and disinfected more frequently – ideally daily, especially in shared spaces or when someone in the household is sick.
For surfaces that are not frequently touched, cleaning and disinfecting can be less frequent. Use your judgment based on the specific circumstances. In general, cleaning visibly dirty surfaces should always be done immediately. It’s also important to remember that cleaning and disinfecting are just one part of preventing the spread of COVID-19; handwashing, mask-wearing, and social distancing remain crucial preventative measures.
What are some best practices for cleaning and disinfecting surfaces?
