Highlights
- Pre-Op focuses on surface readiness; Post-Op focuses on soil removal and shutdown.
- Visual inspections catch missed debris, cross-contamination risks, and wet surfaces.
- A simple Clean → Inspect → Disinfect workflow creates cross-shift accountability.
- Rinse and air dry steps prevent residue buildup on food-contact surfaces.
- HOCl is a safer alternative for high-touch and prep areas because it leaves no harsh fumes.
- Standardized checklists reduce training time and help maintain consistent outcomes.
Understanding Pre-Op and Post-Op Sanitation in Commercial Kitchens
Running a commercial kitchen means every shift begins and ends with a consistent sanitation routine. Pre-Op and Post-Op workflows aren’t just housekeeping — they help maintain safer food-contact surfaces, prevent cross-shift contamination, and build accountability across teams. This article breaks down an easy-to-follow Pre-Op and Post-Op checklist designed for commercial kitchens, food plants, and commissary environments.
Follow all local regulations and product label directions.
If your team needs a safer, no-rinse option for food-contact surfaces, explore the School & Workplace Collection on the CleanSmart Canada website.
The Difference Between Pre-Op and Post-Op Sanitation
Pre-Op (Before Production Starts)
The goal is to prepare a clean, dry, residue-free workspace. This includes visual inspection, touchpoint verification, and confirming that the previous shift completed their shutdown tasks.
Post-Op (After Production Ends)
This workflow focuses on removing soils, debris, and organic load before disinfecting or sanitizing. Surfaces should be left clean, rinsed (where required), and allowed to air dry.
Both routines rely on the same logical sequence:
Clean → Inspect → Disinfect → Rinse → Air Dry.
Pre-Op Sanitation Checklist (Before Production)
1. Remove Visible Debris
Brush, wipe, or collect crumbs, residues, and packaging fragments from prep stations, slicers, scales, and work tables.
2. Wash Surfaces
Apply a cleaning solution and remove soils from stainless steel tables, sinks, cutting surfaces, and equipment exteriors. Cleaning always comes before disinfection.
3. Rinse (If Required)
Some cleaners require rinsing. Follow product label instructions and site protocols.
4. Inspect Surfaces
Use both visual and tactile checks:
- Are surfaces completely free of residue?
- Are corners and underside edges clean?
- Are areas fully dry before disinfecting?
5. Disinfect Food-Contact Surfaces
Use a disinfectant appropriate for your workspace. Hypochlorous acid (HOCl) technology, such as CleanSmart’s 1 L Surface Cleaner & Disinfect, can be applied without leaving strong fumes.
6. Allow to Air Dry (Where Applicable)
Drying time supports proper contact duration and surface readiness.

Post-Op Sanitation Checklist (After Production)
1. Breakdown & Remove Food Soils
Clear tools, trays, prep pans, and utensils. Scrape, wash, and soak as required.
2. Clean All Surfaces
Remove grease, proteins, starch buildup, and other organic materials from:
- Counters
- Workstations
- Sinks
- Handles, knobs, and touchpoints
3. Rinse Thoroughly (If Required)
Ensure surfaces are free of detergent or cleaning residues.
4. Disinfect Work Areas
Apply your approved disinfectant to:
- Cutting boards
- Prep tables
- High-touch zones
- Equipment exteriors
- Cold room handles
5. Air Dry and Leave Surfaces Ready for Pre-Op
A clean, dry surface is the first signal for the next team that the area is safe to use.
Building Accountability Across Shifts
Commercial kitchens often run multiple shifts. A structured Pre-Op and Post-Op workflow helps:
- Reduce downtime
- Standardize expectations
- Create audit-ready documentation
- Minimize cross-contamination
- Improve team communication
Posting the checklist in prep areas, dish pits, and production zones ensures visibility.

Frequently Asked Questions (FAQs)
Q1. What is the difference between Pre-Op and Post-Op sanitation?
A. Pre-Op prepares surfaces for production, while Post-Op focuses on soil removal and disinfecting before closing the shift.
Q2. Can HOCl be used on stainless steel prep tables?
A. Yes. Hypochlorous acid is compatible with stainless steel and leaves no harmful fumes.
Q3. Do all cleaners need to be rinsed?
A. No. Follow product label directions. Some cleaners require rinsing, while HOCl-based solutions do not leave chemical residues.
Q4. Why is air drying important?
A. It ensures surfaces remain residue-free and ready for the next shift’s Pre-Op inspection.
