The Chef’s Guide to Cleaning and Sanitising
Cleaning and sanitising is a basic yet vital step in a professional kitchen. It revolves around the discipline of cleaning during the day and between various tasks to prevent the transfer of pathogens. For a Head Chef, this pillar is the primary defence against cross-contamination. Within the HFS scientific logic, we distinguish between the daily operational discipline of clean-as-you-go and the structural necessity of deep cleaning.
2.0 Clean as You Go: The Operational Standard
The concept of clean as you go is the heartbeat of a safe kitchen. It ensures that bacteria do not have the opportunity to move from raw ingredients to ready-to-eat products. It is essential to implement this discipline during specific high-risk intervals:
- Between the preparation of raw meats and ready-to-eat food.
- After completing any cleaning tasks that involve chemicals or waste.
- Whenever a chef leaves their work station or switches sections.
3.0 The Two-Step Scientific Method
Many kitchens fail because they rely on a one-step process. However, international best practice and HFS standards dictate a two-step method. This is the only proven way to remove organic soil and kill Salmonella, E. coli, and other bacteria.
- Remove excess dirt, food debris, or grease from the surface.
- Spray on a multi-purpose cleaner to break down the remaining surface film.
- Wipe off using a clean material cloth. The physical scrubbing action is often more effective at removing bacteria than the chemical alone.
- Spray on a registered sanitiser over the now-clean surface.
- Allow for sufficient contact time—ideally 3 to 5 minutes.
- Wipe off with a disposable paper towel to ensure no chemical residue remains.
Bacteria can hide behind layers of grease and protein. If you spray a sanitiser directly onto a dirty surface, the chemical is neutralised by the organic matter before it can reach the pathogens. This is why the physical cleaning step must always precede the sanitising step. Without removing the grease first, the sanitation is an expensive waste of time.
4.0 Chemical Standards and Contact Time
Using an approved supplier is critical. Chemicals, especially sanitisers, should be registered and tested against local or international standards (such as EN 1276 in the UK). Sanitisers should be correctly diluted via an automatic dispenser to prevent chemical waste and ensure effectiveness.
Be wary of suppliers who promise instant results. The contact time for the sanitiser is paramount to its success. We advocate for a 3 to 5-minute window to ensure a 99.999% kill rate. Chemicals must also be correctly labelled at all times to prevent the catastrophic error of a cleaning agent being mistaken for a food ingredient.
5.0 Deep Cleaning Strategy and Risk Categories
Deep cleaning in the kitchen is distinct from daily maintenance. While the priority of the brigade is to serve food, the priority of the facility is to prevent bacteria from growing in hard-to-reach areas. To manage this without disrupting service, Chefs must develop a cleaning schedule based on risk:
- Critical (Daily): Food contact areas, cutting boards, and high-risk equipment. These items require both clean-as-you-go and end-of-shift deep cleaning.
- Major Risks (Weekly): Shelves, basins, door handles, and storage racks. These items come into indirect contact with food and can harbor pathogens if neglected.
- Minor Risks (Monthly/Quarterly): Walls, floors, table legs, and heavy cooking equipment. These areas build up dirt over time and require planned resource allocation to clean effectively.
Technical Note: The Table Paradox
You will notice that prep tables appear in both daily and weekly schedules. This is because tables are the primary workhorse of the kitchen. While they are cleaned constantly during service, a weekly deep clean is required to address the undersides, legs, and joints where grease and bacteria accumulate out of sight.
6.0 HFS Master Control: The Cleaning Schedule
A cleaning schedule is the only effective method to ensure all areas are addressed in a time-efficient manner. It moves the responsibility from a vague instruction of “keep it clean” to a specific, auditable task. To implement this, list every item in your kitchen and assign it a frequency and a responsible person.

Summary for the Kitchen Brigade
Cleaning is the foundation of culinary professionalism. By mastering the two-step method and adhering to a strict cleaning schedule, a Chef ensures that the kitchen remains a laboratory of safety rather than a source of illness. A clean kitchen is a profitable, efficient, and respected kitchen.
