What is the difference between cleaning and sanitizing?

• A. They are the same process
• B. Sanitizing removes dirt; cleaning kills pathogens
• C. Cleaning removes dirt; sanitizing kills pathogens
• D. Both processes remove dirt

Answer: (C)

Cleaning and sanitizing are two steps with different purposes. Cleaning removes dirt, soil, and residues from a surface using soap or detergent and water, often with physical scrubbing. Sanitizing reduces the number of microorganisms on the surface to a level considered safe, typically using a chemical sanitizer or heat. The key distinction is that cleaning targets visible dirt and debris, while sanitizing targets microbes to lower their count to safe levels. In practice, you clean first to remove soil, then sanitize to reduce pathogens, and you must follow the sanitizer’s label for concentration and contact time. The other statements mix up the roles or say they’re the same, which doesn’t reflect how these two steps function together.
