How To Prevent Cross Contamination At The Office

Jul 23, 2020

During the COVID-19 pandemic, it’s safe to say that nearly everyone has increased the amount they are cleaning. Between handwashing and disinfecting frequently touched surfaces, we have all had a crash course in Cleaning 101. But, did you know that even while cleaning or disinfecting, it is possible to spread germs from one place to another? For workplaces especially, this can be a critical problem. However, by changing a few aspects of your regimen, you can prevent cross contamination at the office.

According to the CDC, routine cleaning and disinfecting is an important part of keeping the workplace as safe as possible. However, the method you use is just as important. There are a few tips to keep in mind to reduce the likelihood of cross-contamination.

Label Everything

Follow dilution and application instructions closely. If you are using a diluted solution in a unmarked bottle, it is important to add a label to specify what is in the bottle and how to use it. When diluting powerful chemicals, labeling prevents the wrong chemicals from getting mixed together, or mixed up. For example, never mix bleach with ammonia or vinegar. Unless your bottles are clearly labeled, accidents can happen. In addition to labeling, color coding can help you keep your tools and solutions separate. The British Institute of Cleaning Science offers a standardized color chart that you may choose to implement in your office. This type of color coding and labeling is an excellent practice for cleaning and disinfecting any time, but especially now as we work to curb the spread of COVID-19.

Invest In Quality Tools

If your cleaning tools are worn, broken, or ineffective, consider upgrading before re-opening your office. Microfiber cloths, for example, actually help attract particles and trap them. Using microfiber cloths instead of cotton or terry can reduce the likelihood that you are spreading the germs around as you wipe. As a result, it also reduces the potential for cross contamination at the office. Microfiber cloths come in a wide variety of colors and can last for years. The material works well for wiping cloths as well as wet mop material.

Start High

Most professional cleaning companies already do this, but it’s worth mentioning. As you wipe down surfaces, dust and particles that are not picked up initially will fall to the floor. Following the wipe down, disinfect the surfaces and allow to dry. Finally, vacuum and mop the floors. Cleaning the floor last allows you to collect anything remaining without re-contaminating the surfaces you have already cleaned and disinfected.


One of the best ways to avoid cross contamination at the office is to actually assign different people to clean and disinfect specific areas. This way, tools are not being transferred from the bathrooms to the kitchens.
