What is the correct definition of clean according to the material?

• A. The visible condition of a surface
• B. A surface free of all microorganisms
• C. A surface that is completely sterile
• D. A surface that is always dry

Answer: (A)

Clean is about the visible condition of a surface—whether it looks free of soil, dirt, or residues. This concept focuses on removing what you can see so the surface appears clean and is ready for the next steps, like disinfection. It does not require removing every microorganism—that's the realm of disinfection or sterilization. Likewise, a surface doesn’t have to be dry to be considered clean; moisture can be present as long as there’s no visible soil. That’s why the best description is the surface’s visible cleanliness.
