Hygiene in schools

In schools, floor surfaces wear out, furniture surfaces may appear scratched, and cloakroom areas can become littered. The cleaning objectives in schools thus emphasize the maintenance of functionality and the condition of surfaces.

In our guidelines, you will find information about the cleanliness of schools, that are typically bustling with indoor traffic. Classrooms, entrances and corridors endure heavy usage. Special attention to frequently touched surfaces such as doorknobs, desks, chairs, and shared equipment, especially with probiotic cleaning agents, ensures a safe environment for all students and staff members.

Utilizing the school holiday periods in cleaning

Mechanical cleaning and maintenance tasks in classrooms and other spaces within schools are better to be scheduled for times when students are on vacation and classrooms are vacant for a sufficient duration. Summer holiday season is optimal for comprehensive basic cleaning measures, including deep cleaning of all surfaces and polishing floors if necessary.


Floor maintenance is an important part of regular maintenance of premises. Daily cleaning aims to maintain the agreed cleanliness level, while basic cleaning is less frequent and more thorough. Both are carried out according to a pre-agreed plan.

Correct cleaning agents and methods are chosen according to the floor material. It’s also important to pay attention to the correct dosing to ensure the desired level of cleanliness.

Tip! Clean floors thoroughly with a universal cleaning agent, such as the Kiilto Pro Universal Probio, three times a week and to preserve the beautiful appearance of floors, use a caring agent, like Kiilto Pro Illusia 10, twice a week. This way the cleaning machine can be used every weekday, but for different tasks.

In staircases or smaller areas, where machine methods are not possible, floors can be cleaned and maintained manually. As with machine methods, taking care to prepare solutions properly and thoroughly clean the surface is essential. You can find instructions for cleaning different floor materials, such as rubber floor, in our floor care section.


Toilet facilities in schools undergo regular and meticulous cleaning to maintain high standards of hygiene
and sanitation. Cleaning schedules typically involve multiple daily inspections and cleanings. Toilet bowls, sinks, and other fixtures are cleaned using appropriate cleaning agents to eliminate germs and bacteria.

Moreover, restocking essential supplies such as toilet paper, soap, and hand sanitizer is a priority to uphold
cleanliness standards and promote good hygiene practices among students, teachers and other staff members.

Additionally, periodic deep cleaning sessions are conducted to address hard-to-reach areas and to
prevent the buildup of grime and odors. This comprehensive approach to restroom maintenance helps
create a comfortable and hygienic environment conducive to the well-being of everyone within the school
