Colour Coding in Commercial Cleaning Explained
Using colour-coded cleaning equipment helps reduce the risk of cross-contamination.
One of the simplest ways to improve workplace hygiene is to use a colour-coding system for cleaning equipment. By assigning different colours to different areas, businesses can help prevent bacteria and contaminants from being transferred from one location to another.
Colour coding is widely used across healthcare, care homes, schools, hospitality, catering and commercial cleaning environments, but it's equally useful in offices and other workplaces.
Having a clear system also makes it easier for staff to know which equipment should be used where.
Why Is Colour Coding Important?
Using the same cloth or mop throughout a building can spread bacteria between different areas.
A colour-coding system helps:
- Reduce the risk of cross-contamination.
- Improve workplace hygiene.
- Make cleaning procedures easier to follow.
- Support consistent cleaning standards.
- Protect staff, customers and visitors.
Choose the Scheme for Your Setting
Always follow your organisation's approved colour-coding policy and the guidance applicable to your setting. Colours are not a universal label for risk: different official schemes give yellow different meanings. Do not change an established system without checking with the person responsible for cleaning or infection prevention.
For example, NHS England's National Standards of Healthcare Cleanliness 2025, section 6.2, uses the following scheme:
🔴 Red
Bathroom facilities, including toilets, showers, washroom basins and bathroom floors.
🔵 Blue
General areas, including wards, departments, offices and basins in public areas.
🟢 Green
Catering departments, ward kitchens and patient food-service areas.
🟡 Yellow
Isolation areas in this NHS England scheme, rather than every clinical or treatment area.
Why You May See Different Advice
UKHSA's guidance for children and young people's settings gives an example using yellow for hand-wash basins and sinks, red for toilets and washrooms, blue for general areas and green for kitchens. Dental guidance in HTM 01-05, section 6.53 (PDF) describes yellow for clinical and decontamination areas. These examples are setting-specific: confirm the scheme your organisation is required to follow before ordering or labelling equipment.
Colour Coding Doesn't Just Apply to Cloths
Many workplaces also colour code:
- Buckets
- Mops
- Mop heads
- Brushes
- Cleaning gloves
- Cleaning trolleys
Using matching equipment throughout your cleaning routine helps maintain consistency and reduces mistakes.
Train Your Team
A colour-coding system only works if everyone understands it.
Simple wall charts, staff training and clear labelling help ensure equipment is always used correctly.
Regularly replacing worn cloths and damaged equipment also helps maintain hygiene standards.
