How many cloths do I need per room?

Best practice is 4 cloths per room using the colour-coding system: blue for general areas, red for washrooms, green for kitchen/food areas, and yellow for clinical/isolation areas. Using different colours prevents cross-contamination between high-risk and low-risk areas.

What is the colour-coding system for cleaning cloths?

The British Institute of Cleaning Science (BICSc) colour-coding system is: RED for washrooms and toilets, BLUE for general low-risk areas (offices, corridors), GREEN for food prep and kitchen areas, and YELLOW for clinical or isolation areas. This system prevents cross-contamination.

How long do microfibre cloths last?

Quality microfibre cloths can withstand 200-500 wash cycles before losing effectiveness. At 60°C washing, most cloths maintain performance for 300+ washes. Replace when cloths no longer feel soft, start to smell even after washing, or visibly lose their pile and absorbency.

How many cloths should I have in total stock?

Keep enough cloths for at least 2 days of use — while one set is in use, the other set can be laundered and dried. This means if you use 20 cloths per day, you need at least 40 in stock. Having 3 sets provides more flexibility for laundry scheduling.

How We Calculate This

How the calculation works

This calculator estimates cloth needs based on the number of rooms and colour-coded cloths per room.

Formula

Daily cloths = rooms × cloths per room

Weekly cloths = daily × cleaning days per week

Total stock = weekly × 2 (for wash rotation)

Replacement cycle = wash cycles × stock ÷ weekly usage

We recommend a minimum of 2 full sets to allow for laundering rotation.
