A colour-coded microfiber system assigns one cloth colour to each zone so cloths used on toilets never touch kitchen counters. The most common convention is red for toilets and urinals, yellow for other washroom surfaces, blue for general areas and green for kitchens and food areas.
The common four-colour convention
| Colour | Use for | Never use for |
|---|---|---|
| Red | Toilets and urinals | Anything else |
| Yellow | Washroom sinks, counters, dispensers, partitions | Kitchens, food areas |
| Blue | Offices, desks, glass, general surfaces | Washrooms |
| Green | Kitchens, breakrooms, food-contact areas | Washrooms |
Rolling it out
- Post the colour chart in every janitor closet and on carts.
- Stock enough of each colour for a full shift so staff never substitute.
- Wash colours separately or in mesh bags, and keep red cloths in their own load.
- Skip fabric softener and bleach: both clog microfiber and reduce how much it picks up.
Common questions
Is there an official microfiber colour code?
There's no single legal standard. The red, yellow, blue, green convention is widely used; what matters most is that your whole team follows one chart.
How often should microfiber cloths be replaced?
Replace cloths when they feel stiff, stop picking up dust, or show wear. Washing without softener and at moderate temperatures extends their life.
