How frequently should the walls and ceiling of a clean room be washed and sanitized?

The cleaning and sanitization schedule for clean rooms is critical to maintaining a controlled environment, particularly in pharmacy settings where sterile preparations are made. Washing and sanitizing the walls and ceiling on a monthly basis strikes a balance between maintaining cleanliness and managing operational efficiency.

In a clean room, dust, particulate contamination, and microbial growth can significantly impact the sterility of products being prepared. Monthly cleaning ensures that these surfaces are kept in optimal condition, reducing the risk of contamination.

Daily or weekly cleaning schedules may be excessive and could require significant labor resources without proportionate benefits, especially if airflow dynamics and other cleanup processes are already in place. On the other hand, cleaning every 6 months could allow for the accumulation of contaminants, increasing the potential for contamination during compounding procedures. Therefore, the monthly schedule is the most effective and practical for ensuring cleanliness in a clean room setting.
