At a minimum, how often should PT sanitize the walls and ceilings of a clean room?

• A. Weekly
• B. Monthly
• C. Daily
• D. Quarterly

Answer: (B)

Regular cleaning frequency is driven by how likely a surface is to harbor contaminants and how often it is touched. Walls and ceilings in a clean room aren’t typically contacted or in direct contact with sterile products, so they don’t accumulate residues as quickly as floors or benches. Because of this, sanitizing them at least once a month is a reasonable minimum to control dust and microbial buildup without overdoing maintenance. Daily cleaning usually targets floors and work surfaces that directly contact products, while more frequent cleaning would be required if a spill or contamination event occurs. Always follow your facility’s SOPs and applicable standards for any deviations.
