Preventing Germs: How Summer Cleaning Protects Schools Year-Round

Schools are full of life, learning, and unfortunately, germs. Every day, students and staff bring in and spread bacteria and viruses through high-touch surfaces, shared materials, and close contact. While daily cleaning during the academic year plays an important role, it’s the deep summer cleaning that gives schools the upper hand in preventing germs from taking hold. When classrooms and hallways are quiet, there’s a critical opportunity to break the cycle of infection before the next school year begins.

Continue reading to explore how strategic summer cleaning prevents the spread of germs and the areas that need the most attention, and discover why partnering with school janitorial services makes all the difference.

Why Summer Is the Best Time for Germ Prevention

Even the most dedicated custodial staff are limited by time and daily demands during the school year. Summer provides a window to clean and sanitize beyond the surface.

By targeting the places where germs hide, removing buildup that routine cleaning can miss, and applying long-lasting disinfectants, schools can drastically reduce the risk of infection when students return.

This proactive approach to preventing germs helps schools:

Start the year with cleaner, safer classrooms
Lower the chances of outbreaks during flu season
Build good hygiene habits in a healthier environment

Proper summer cleaning isn’t just a once-a-year chore. It’s a powerful investment in the health and well-being of everyone who walks through your doors.

The Science of Germ Spread in Schools

Understanding how germs spread helps explain why summer deep cleaning is so effective. Germs are passed through touch, air, and surfaces, and schools are full of all three.

Students touch desks, door handles, lockers, and tech devices all day long. Germs can live on these surfaces for hours or even days, especially in enclosed spaces with little airflow.

Respiratory viruses like the flu and COVID-19 can travel through the air or settle onto surfaces. If a student touches a contaminated surface and then their face, they can easily get sick. That’s why high-touch areas need more than just a quick wipe—they need thorough, professional disinfection for schools.

Before we break down the top germ hotspots, let’s take a closer look at what makes a summer cleaning routine so powerful.

What Makes Summer Cleaning So Effective?

With empty classrooms and no daily interruptions, cleaning crews have the time and access they need to reach every surface, corner, and crevice. The summer months allow for:

Extended dwell times for disinfectants, ensuring more effective germ kill
Use of electrostatic sprayers and fogging machines that reach hard-to-clean areas
Deep cleaning of surfaces that are often skipped during routine cleanings

This level of thoroughness is hard to achieve during the academic year, when janitorial staff are focused on quick turnaround between school days.

Done right, summer cleaning becomes a foundation for better hygiene throughout the entire school year.

Germ Hotspots That Require Summer Focus

Not all areas in a school carry the same level of germ risk. Some surfaces and spaces see much more activity and exposure, making them prime candidates for enhanced cleaning.

Desks and Classroom Furniture

Students spend hours at their desks, often eating, sneezing, or touching shared supplies. Wiping down every surface, including chairs, tables, whiteboards, and shelving, helps eliminate hidden bacteria.

Restrooms and Locker Rooms

These areas are a major priority for disinfection in schools. High humidity and frequent use make them ideal environments for germs to multiply. Cleaning teams should scrub and sanitize toilets, sinks, stalls, and floors, and check ventilation systems.

Cafeterias and Kitchens

Shared eating spaces demand food-safe cleaning products and extra care. Tables, trays, prep surfaces, and high-touch zones like fridge handles and serving lines should all be disinfected thoroughly.

Door Handles, Railings, and Switches

Touched dozens, even hundreds of times per day, these are the silent culprits behind many infections. Summer cleaning should include disinfecting every handle, button, and railing in your building.

Tech and Shared Equipment

Classroom computers, tablets, smartboards, and lab tools are used by many hands each day. Specialized cleaning methods are needed to disinfect them without damage.

By giving extra attention to these high-risk areas, schools dramatically reduce the chance of bacteria surviving into the new school year.

Summer Cleaning Sets the Tone for the Year

When students walk into a clean, fresh-smelling building, it sends a message. It tells families you care about their child’s health. It builds confidence among teachers. And it encourages students to take care of their environment.

Starting the year off with clean desks, sanitized restrooms, and well-maintained classrooms helps prevent illness and sets the tone for personal responsibility and respect.

Just as importantly, it can help schools avoid the early-year spike in colds, stomach bugs, and other illnesses that often spread rapidly through classrooms.

Prevent Illness by Cleaning Beyond the Surface

Surface-level cleaning is helpful, but it’s not enough to prevent illness. Schools must go deeper to truly break the chain of transmission.

Professional cleaning crews can:

Use EPA-approved disinfectants proven to kill bacteria and viruses
Apply sanitizers to both hard and soft surfaces, including carpets and furniture
Disinfect ventilation systems to improve air quality

Even items like gym equipment, musical instruments, and playground structures should be cleaned and disinfected before students return. With the right cleaning methods and tools, germs have fewer places to hide.

Why Professional Help Matters for Preventing Germs

While your in-house custodial team does an amazing job during the school year, summer cleaning requires extra time, manpower, and expertise.

A professional partner like Brenner Facility Services brings:

Certified technicians trained in school-specific sanitation
Advanced tools such as electrostatic sprayers and fogging units
A strategic plan tailored to your school’s unique needs
Experience with cleaning high-risk areas and hard-to-reach spaces

Partnering with professionals ensures that no surface is missed and that your school is fully prepped for the return of students and staff.

The Long-Term Benefits of a Healthy Environment

Preventing germs in schools goes beyond just cleaning. It’s part of creating a culture of health and safety. When students stay healthier, they attend school more consistently. When staff avoid illness, schools operate more smoothly.

A summer deep clean isn’t just a seasonal task—it’s the foundation for:

Lower absenteeism
Higher staff retention
Improved academic performance
Greater trust from families and the community

It also helps schools stay compliant with public health guidelines and reduces liability risks.
