Cleaning vs Sanitizing

Cleaning and sanitizing are two separate but connected steps in food-premises hygiene. Cleaning removes food residue, grease, dirt and other soil from a surface. Sanitizing reduces microorganisms on a properly cleaned food-contact surface to a level considered acceptable under the applicable standard.

Correct sequence for food-contact surfaces

1. Remove debris: scrape or wipe away food particles and loose soil.
2. Wash: use the approved detergent and method to remove grease and remaining soil.
3. Rinse: remove detergent and loosened residue when required by the procedure.
4. Sanitize: apply an approved sanitizer at the specified concentration, temperature and contact time.
5. Air-dry: allow the surface to dry as directed by the product label and local requirements; do not wipe away the sanitizer prematurely.

Why cleaning must come first

Food residue and grease can physically shield microorganisms and interfere with sanitizer performance. Applying sanitizer to a dirty surface does not replace proper cleaning. The surface must be cleaned first so the sanitizer can contact the area effectively.

Cleaning versus sanitizing versus disinfecting

Cleaning removes soil. Sanitizing reduces microorganisms on food-contact surfaces to the required level. Disinfecting is a different process generally used for non-food-contact surfaces or specific public-health purposes and may involve products not approved for direct food-contact use.

Chef’s tip: Use test strips or another approved method to verify sanitizer concentration, and follow the label for contact time and rinse requirements. Never mix cleaning chemicals.

Key distinction: Cleaning removes soil; sanitizing reduces microorganisms after cleaning. Both steps are necessary for effective food-contact surface hygiene.
