Four-Color System: Definition and Application in Building Cleaning

How does the Four-Color System work?

The four-color system has become an established method in building cleaning. It helps prevent the spread of germs and ensures long-lasting hygiene by using different colored cleaning cloths for specific cleaning areas. The colors used in the four-color system are red, blue, yellow, and green.

When cleaning with the four-color system, the cloth rotation method is also used. This means that a fresh cloth is used for each new room or cleaning area. Used cleaning cloths are washed at the designated temperature before their next use.

What colors are there and what do they mean?

• Red cleaning cloths are used for toilets and urinals, as well as the surrounding tiled areas.
• Yellow cleaning cloths are used in the rest of the bathroom for tiles, sinks and shelves, fixtures, mirrors, shower cabins, and bathtubs.
• Green cleaning cloths are used for kitchen areas and hospital rooms.
• Blue cleaning cloths are used for cleaning surfaces, furniture, and objects in living rooms, children's rooms, and offices.
