The world was put to a halt when the pandemic hit in 2020. This global health crisis has highlighted the importance of making sure that observe have the proper cleaning and disinfecting measures to help prevent the spread of infectious diseases. Below are some tips for reducing the spread of infectious diseases in schools through cleaning and disinfecting.

1. Learn the Difference Between Cleaning and Disinfecting

Cleaning and disinfecting are two different things. Cleaning is the process of removing dirt, germs and impurities from objects or surfaces. This method does not essentially kill germs, but it reduces the amount and the possibility of spreading infection.

On the other hand, disinfecting is the process of using chemicals on surfaces or objects to destroy bacteria. This process is usually done after the cleaning.

2. Prioritise Cleaning and Disinfecting Frequently Touched Objects and Surfaces

Clean and disinfect materials and surfaces that are frequently touched, such as door knobs, desks, faucets, handrails, computer keyboards, toys, countertops, toilets, sinks and basins. Noticeably dirty surfaces should be cleaned right away.

Follow standard precautions and use necessary cleaning gear, such as gloves and mask, when removing soiled objects with blood or body fluids to prevent contact with such fluids. After removing the spill, clean and disinfect the object or surface.

3. Perform Regular Cleaning and Disinfecting

Standard cleaning and disinfecting routines are sufficient to kill flu viruses. It is not mandatory to close schools when doing routine cleaning and disinfecting to reduce the spread of the flu. Fumigating or spraying air deodorisers is unnecessary and not recommended. Such methods can hurt the eyes, throats, and skin; worsen asthma; and may cause undesirable aftereffects.

4. Clean and Disinfect Properly

Apply disinfectant or detergent solution when cleaning surfaces that are often touched at least every day or when noticeably soiled. Use EPA-registered cleaning products and disinfectants to eliminate germs and viruses.

For surfaces that are not touched often, like ceilings, floors and walls, use detergent solutions or wipes to clean general exteriors. Clean blinds and walls when visibly dirty. Vacuum carpeted floorings and ensure the vacuum has a high-efficiency particulate air filter. Remember to vacuum only when there are no more people around.

The school’s common areas such as the toilets, gym, canteen and main office must be cleaned and disinfected at least every day and when noticeably dirty.

Routine cleaning of outdoor areas is also needed. However, spraying disinfectant on wooden surfaces like tables and benches is discouraged. You may perform routine cleaning and disinfecting on frequently touched outdoor surfaces made of metal or plastic.


5. Read the Labels on the Cleaning Products

Be sure to read the directions and warnings on the cleaning product labels. Follow the directions when sanitising or disinfecting regarding the dwell time of the product on the surface and rinsing procedures, if there are any. Always wear gloves when using any chemical cleaning solutions. Wear protective eyewear and a mask for extra protection.

The custodial staff and other school staff who use cleaning and disinfecting products must understand how to use them properly. The school should provide training and instructional materials to avoid accidents when using cleaning products and disinfectants.

6. Proper Waste Disposal

Handle waste disposal properly. Abide by your school’s standard system for managing waste, such as wearing gloves to prevent direct contact with potentially infectious materials and when handling contaminated objects or surfaces.

Throw one-use or disposable items right away in the garbage bin after use. Do not touch used tissues and other garbage when emptying trash cans. Always wash your hands with soap and water after dealing with the trash.


Schools are very prone to infectious diseases such as flu and cold since many students and staff move in and out of the classrooms daily. Cleaning and disinfecting routine must be implemented properly in all schools to reduce the spread of infectious diseases. Follow the tips above on how to clean and disinfect the right way and how to handle waste materials properly.
