Sanitizing Stainless Steel in Commercial Kitchens
Beyond cleaning, sanitizing stainless steel in commercial kitchens is paramount for food safety. Sanitizing kills bacteria and other microorganisms.
When to Sanitize
- After cleaning, especially if there’s been contact with raw meat, poultry, or fish.
- Between tasks involving different types of food.
- Regularly throughout the workday, as per your establishment’s hygiene protocols.
Effective Sanitizing Methods
- Approved Sanitizing Solutions: Use commercially available sanitizing solutions approved for use in food service environments. These are typically quaternary ammonium compounds (Quats), peracetic acid, or chlorine-based sanitizers. Always follow the manufacturer’s dilution and contact time instructions precisely.
- Heat Sanitizing: For items that can be immersed, hot water (at least 170°F or 77°C for 30 seconds) is an effective sanitizer. This is often done in commercial dishwashers.
- Alcohol-Based Sanitizers: Isopropyl alcohol (70-90%) can be used as a sanitizer. Apply to a cloth and wipe the surface, allowing it to air dry.
Important Sanitizing Considerations
- Clean First: Sanitizers are not cleaners. Surfaces must be thoroughly cleaned before sanitizing to be effective.
- Contact Time: Most sanitizers require a specific contact time to kill bacteria. Ensure the surface remains wet with the sanitizer for the recommended duration.
- Rinse (If Required): Some sanitizers require rinsing with potable water after the contact time, while others are “no-rinse.” Always check the product label.
- Ventilation: Ensure adequate ventilation when using chemical sanitizers.
