What is the difference between cleaning and sanitizing?

• A. Cleaning removes dirt; sanitizing reduces germs to safe levels.
• B. Sanitizing removes dirt.
• C. Cleaning eliminates all germs.
• D. Sanitizing sterilizes surfaces.

Answer: (A)

Cleaning and sanitizing have different goals when we keep surfaces safe. Cleaning removes dirt, grease, and other visible soil with soap and water, which physically lifts residues off a surface. Sanitizing then lowers the number of germs to a level considered safe by health standards, using chemical sanitizers or heat. So cleaning is about dirt removal, while sanitizing is about reducing germs to safe levels. They often work together: you clean first to remove soil, then sanitize to minimize microbial contamination. The other ideas mix up these roles—removing dirt isn’t the same as reducing germs, cleaning alone doesn’t guarantee all germs are gone, and sanitizing isn’t the same as sterilizing, which would kill every microorganism.
