Cleaning, disinfection, sterilization: what's the difference?
An essential part of management of a successful business is to maintain a clean environment. Whether you're keeping track of your cleanliness using a cleanliness checklist or scheduling, making sure your location is cleaned regularly can help keep your staff and customers healthy.
It is important to understand the different depths of cleaning to decide what method and practices you should take in your location to stop the spread of diseases and viruses. We will explore the differences between cleaning, disinfecting, and sterilizing so that you can better incorporate them into your cleaning regimen.
What is the difference between cleaning and disinfecting?
The main difference between cleaning and disinfection cleaning is the act of cleaning debris and deposits on a surface, while disinfection involves killing bacteria after the surface has already been cleaned.
When comparing cleaning to disinfection, you want to make sure that cleaning is done first, regardless of the surface, and that disinfection continues to be area dependent. Items that come into contact with food and are often touched need to be disinfected, whereas places like hallway floors and windows do not need to be disinfected regularly as they are considered low risk surfaces.
Cleaning something means removing all visible surface contamination, including dirt, spills, food particles, dust, etc., by washing, brushing or cleaning the area. This process is superficial and does not kill germs, but it can help reduce their number. This is expected to be the first step in the cleaning process. Common cleaning products include:
- Feather dusters
- Glass cleaners
Disinfecting means reducing the amount of microorganisms such as bacteria, viruses, and fungi on a surface after it has been cleaned. The disinfectant used must reduce the amount of bacteria to the level that public health regulations consider safe. To meet CDC requirements, sanitizing chemicals must kill 99.999% of test bacteria in less than 30 seconds.
Although disinfection reduces the growth of harmful bacteria, it does not kill all viruses on a surface. Disinfection is intended to be used as a preventive measure and is an extremely important practice in restaurants, schools, corporate offices and hospitals. Every surface that comes into contact with food should be disinfected regularly, often several times a day.
Disinfect vs. sterilize
The difference between disinfecting and sterilizing is based on the amount of bacteria that each process eliminates. While disinfection claims to kill most germs, it cannot make antiviral claims. Disinfection is more powerful than disinfection and can kill almost 100% of bacteria, viruses, and fungi, while targeting microorganisms that carry specific diseases such as the influenza virus, norovirus, and coronavirus.
Because disinfection is more intense than disinfection, the disinfectant will often be used in areas with a vulnerable population, such as healthcare facilities and childcare facilities. Disinfection would suffice for food service items like tables and cutting boards, but a disinfectant would be needed for places like bathrooms and gyms.
Disinfecting means killing viruses and specific pathogens on a surface using a disinfectant. These cleaning agents must kill 99.999% of infectious bacteria, viruses, and fungi within 5-10 minutes. Disinfecting frequently touched surfaces is recommended. Bathrooms should always be disinfected due to pathogens that these surfaces can harbor and that can lead to the spread of disease. Common disinfectants include:
Difference between sterilizing and disinfecting
Although the terms are used interchangeably, there are differences between disinfection and sterilization. Disinfection removes almost 100% of viruses and bacteria on surfaces, while sterilization will kill all viruses, bacteria, fungi, and bacterial spores in one item.
While disinfection is useful in most settings and on surfaces that are regularly touched, sterilization is generally only reserved for instruments used in medical facilities and hospital settings.
Sterilizing an item means completely eradicating microbes on its surface, including bacterial spores, bacteria, viruses, and fungi. Health care facilities rely heavily on the sterilization of food, medicine, and equipment to prevent wound infections and the spread of disease from one patient to another. Some methods can be used to sterilize products:
- Chemical products
What is the correct way to disinfect a table that has been used to prepare food?
Follow these steps to disinfect a table that has been used to prepare food:
- Clean: The surface of any visible residue.

- Allow the surface to air dry for a minimum of 30 seconds to one minute to allow the disinfectant to work. Use this time to implement a clean break if your location requires that food preparation be documented in batches and time shifts.
Because of the ease with which bacteria can transfer into food and cause disease, proper disinfection practices are very necessary in food environments. restaurants. It is important to use disinfection methods in your kitchen restaurant to clean tables, cutting boards and utensils for prevent cross contamination This can cause food poisoning and allergic reactions.

Do disinfecting wipes kill viruses?
Because sanitizing wipes have shorter residence times than most sanitizing chemicals, there is concern that they may not have enough time to kill viruses on a surface. The key to successfully disinfecting a surface is reading the details of the cleaning wipes you choose to use. To confidently target viruses such as norovirus, influenza, rhinovirus, and coronavirus, the CDC recommends using disinfectant wipes that contain at least 60% alcohol.
