Using microfibre cloths and a colour-coded cleaning system will result in cleaner, more hygienic facilities. It will also reduce the risk of cross-contamination considerably.
There is no formal national standard for which colour should be used for which application. However, many facilities follow the National Patient Safety Agency colour coding scheme:
Red/pink cloths are often used in bathrooms, where the risk of cross-contamination is higher. This ensures cloths that have been used to clean toilets are never used in offices or in food preparation areas.
Green cloths can be considered all-purpose cloths for cleaning offices and common areas. In healthcare settings, they can also be used for cleaning patient rooms or food preparation areas.
Blue cloths can be used to clean above the floor surfaces in common areas. Glass and polished surfaces are often cleaned with special a blue microfibre cloth. Cloths for cleaning glass or windows have a special silky texture that reduces streaking and dries free of traces.
Yellow cloths are used in the isolation areas of healthcare facilities. In office environments, they can be used to clean areas where the risk of cross-contamination is higher, such as cafeterias or kitchens.
