School Exterior Cleaning: Why It Is So Important To Keep Your School Grounds Clean


When our schools are clean, we have one less thing to worry about when ensuring a safe learning experience. Not only is it important for students’ health, but also keeping our teachers, faculty, and families at home safe as well. 

A clean school can promote positivity, allowing teachers and students to be present and focus more on the educational process, rather than concern for the cleanliness of their surroundings. It’s about more than just being sanitary, it shows school pride, and that the community cares about the place they learn and work.

The spread of germs via dirt and grime promotes the spread of communicable diseases, which can be devastating when passed throughout schools and to other members of the community. Keeping common areas of your school clean, just as you would at home, means less sick days taken by your staff, and fewer absences. 

COVID-19 has put extra focus on cleanliness inside and outside our schools, as well as utilising outdoor space and maintaining the sanitisation of high frequency touched spaces. It’s no longer just our indoor spaces that are an area of concern, but playgrounds or lunch areas are also places we must be vigilant about cleaning and disinfecting. 

Exterior Cleaning School Grounds

Sometimes when focusing on keeping the interior of our school clean, we forget about the exterior high touch surfaces that exist in the hustle and bustle of the school day. More than ever, it’s time to consider all aspects of cleanliness in our schools, especially after COVID-19 has made it difficult for everyone to safely learn in their classrooms. Aside from pathogens, there are other substances around your school property that can negatively affect sanitation — sap, mould, bird droppings, moss, or mildew can all be allergens and transmit bacteria. There are multiple ways to keep the exterior grounds of your school cared for to keep your campus sanitary and presentable for visitors, faculty, and students alike.

1. Concrete Surface Cleaning

School lunch areas, assembly areas, playgrounds, basketball or tennis courts, and other outdoor areas around your school are likely made of concrete. With many of these being high traffic areas, it’s easy for these spots to get dirty quickly. Incorrectly treating concrete can cause damage to its surface, and neglecting to clean these areas can allow buildup of organic substances that cause further damage. Hiring a professional exterior cleaning company will ensure that these areas are cleaned thoroughly, keeping dirt and mould away, as well as promoting the longevity of these areas. 

2. Building Soft Washing

Getting a soft wash done on your buildings can give a major boost to your campus’  appearance and help bolster its reputation. While power washing was the option of choice in the past, newer cleaning technology has made cleaning building exteriors safer and more efficient than ever. 

Soft washing is the absolute best way to clean the exteriors of your buildings, as sometimes power washing can actually be damaging to surfaces and do more harm than good in the long run. High-pressure washing can blast away the gunk from algae or mould on the surface, but doesn’t remove spores, letting algae or mould return and take root in the porous surfaces they grow on. Soft washing includes an application of safe, specialised chemicals that break down dirt, remove mould, and rinse away other small debris; with an added benefit of sanitising surfaces and removing germs as well. By soft washing, you cut down your exterior cleaning costs, ensuring the job is done correctly the first time.

3. High Touch Area Sanitisation 

There are plenty of common outdoor places where dozens — if not hundreds — of students and faculty place their hands throughout the day. These areas, like handrails, doors, benches, tables, or outdoor walls, all need to be kept clean in order to stop the spread of germs. Lunch areas are also places where a lot of students gather, adding drinks and food to the mix of dirt and grime. Prior to every term, it’s recommended to conduct a deep clean via soft washing, and follow up with daily disinfecting of high touch surfaces.

4. Playground Cleaning

We know recess can often be the most fun time of the day, and taking a break to go have a good time with your classmates shouldn’t involve the fear of getting sick. Playgrounds tend to be a breeding ground for harmful bacteria and viruses, and do need to be cleaned and sanitised regularly. Soft washing professionals will use a two-part cleaning, which first removes built up dirt and grime, and then second applies a special grade cleaning formula that helps kill any remaining germs.
