Overview
This SOP template defines the end-of-night closeout for a flat-top plancha station, including safe shutdown verification, scraping, polishing, seasoning, grease trough clearing, final inspection, and photo documentation. It is meant for kitchens that want a repeatable closeout sequence for a single plancha or a small group of matched stations, especially where surface condition and grease control matter for the next service.
Use this template when the station must be left clean, lightly protected, and ready for the next shift without carbon buildup or grease overflow. It is especially useful in restaurants, hotel kitchens, cafeterias, and catering operations where multiple people may close the same station and consistency is important. The photo step makes the final condition visible and gives supervisors a simple record for shift handoff or audit review.
Do not use this SOP as a substitute for deep cleaning, equipment repair, or chemical sanitation procedures that require a separate approved process. If the plancha is still too hot to handle safely, if the grease trough is damaged or blocked, if there is a gas, electrical, or fire hazard, or if the surface coating is flaking or pitted, stop and escalate to a supervisor or competent person. The template is for routine closeout, not maintenance work or hazardous intervention.
Standards & compliance context
- The template supports ISO 9001-style documented information by standardizing the closeout sequence, role assignment, and photo record.
- The cleaning and inspection steps align with HACCP, ServSafe, and GMP expectations for controlled sanitation and prevention of contamination.
- The safety verification step supports OSHA-style hazard control by requiring the operator to check for hot surfaces, grease exposure, and other cleaning hazards before work begins.
- The photo documentation step helps create traceable evidence for internal audits, shift handoff, and non-conformance follow-up.
- If your site uses local food-code, fire-safety, or chemical-handling rules, add those requirements to the station-specific version of this SOP.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Steps
This section matters because it turns the closeout into a controlled sequence with clear actors, verification points, and escalation triggers.
-
The line cook verifies the station is safe to clean
The line cook confirms the plancha gas valve is OFF, the surface temperature is ≤120°F (verified with an infrared thermometer), and no food is on the griddle; record the time and initials before starting.
-
The line cook scrapes food debris from the flat-top surface
The line cook uses the griddle scraper to remove loose food debris and carbonized residue from the cooking surface, working from the back edge toward the trough and keeping hands clear of the blade path.
-
The line cook polishes the cooking surface with a griddle pad
The line cook polishes the cooking surface with the approved griddle pad or screen until visible residue is reduced and the metal is evenly finished without gouging.
-
The line cook applies a thin seasoning layer to the plancha
The line cook applies a thin, even film of approved seasoning oil across the entire cooking surface and wipes away any pooling so no visible excess remains.
-
The line cook wipes the grease trough and clears waste
The line cook wipes the z-trough or grease trough clean, removes all pooled fat and buildup, and disposes of waste in the designated container without leaving residue at the station.
-
The kitchen supervisor inspects the final condition for cleanliness and coverage
The kitchen supervisor confirms the surface is clean, lightly seasoned, and the grease trough is clear with no visible residue or overflow before approving closeout.
-
The kitchen supervisor captures a photo of the completed station
The kitchen supervisor captures a clear photo showing the final condition of the flat-top surface and grease trough after all tools and waste have been removed.
How to use this template
- 1. The closing lead confirms the station is safe to clean by checking heat level, utility status, and any active hazards before assigning the task.
- 2. The assigned operator scrapes loose food debris from the flat-top surface and moves waste into the designated collection point.
- 3. The operator polishes the cooking surface with the approved griddle pad until residue is removed and the surface appears even.
- 4. The operator applies a thin seasoning layer to the plancha and wipes the grease trough clear of waste, pooled fat, and buildup.
- 5. The closing lead inspects the final condition for cleanliness and coverage, then captures a photo of the completed station and records any deviation or escalation.
Best practices
- Verify the plancha is cool enough for safe handling before any scraping or polishing begins.
- Use a thin seasoning layer only; excess oil creates sticky buildup and attracts carbon on the next shift.
- Scrape from the back edge toward the trough in controlled passes so debris does not fall back onto the cooking surface.
- Clear the grease trough before the final inspection so the photo reflects the true closeout condition.
- Treat damaged seasoning, pitting, or flaking as a deviation and escalate it instead of trying to cover it with extra oil.
- Take the final photo after the station is fully reset, not while tools, waste, or towels are still in place.
- Keep the same tool set and sequence across shifts so the closeout result is consistent and easy to audit.

Common use cases
Frequently asked questions
What does this SOP cover?
This SOP covers the end-of-night closeout for a flat-top plancha station: safety verification, scraping, polishing, seasoning, grease trough cleaning, final inspection, and photo documentation. It is designed for a single station or a defined line of planchas, not for a full kitchen deep-clean. The output is a clean, lightly seasoned cooking surface with the Z-trough cleared and documented.
Who should run this procedure?
A trained cook, closing lead, or steward can run it if they are competent in hot-surface handling and chemical-safe cleaning practices. The person assigned should know when to stop and escalate for damaged surfaces, excessive buildup, or a grease management issue. If your site uses permit-to-work or lockout steps for maintenance, those decisions belong to the supervisor or competent person.
How often should this SOP be used?
Use it at the end of each operating day or after the last cooking service on the station. If the plancha sees heavy protein, sugar, or high-fat production, you may also use parts of the procedure between shifts as needed. The key is consistency: the surface should never be left with debris, pooled grease, or an unprotected finish overnight.
Does this template have any regulatory or quality relevance?
Yes. It supports ISO 9001-style documented information by standardizing the closeout and photo record, and it helps reinforce sanitation and food-safety expectations used in HACCP, ServSafe, and GMP programs. Where hot surfaces, grease, or chemical cleaners are involved, the procedure also supports safe work practices consistent with OSHA-style hazard control. It is not a substitute for site-specific food-code or local fire-safety requirements.
What are the most common mistakes with plancha closeout?
Common mistakes include seasoning a dirty surface, leaving carbon buildup at the edges, overapplying oil so it pools, and forgetting the grease trough. Another frequent issue is taking the final photo before the station is fully dry or before waste is removed. This SOP is built to catch those failures with explicit verification steps.
Can I customize this for different oils, tools, or station layouts?
Yes. You can swap in your approved seasoning oil, change the scraper or pad type, and rename the grease trough to match your equipment, such as a Z-trough or drip channel. You can also add local requirements for PPE, chemical contact time, or waste handling. Keep the step order intact so the cleaning and seasoning sequence stays controlled.
How does this compare with ad-hoc closing routines?
Ad-hoc routines often miss one of the critical controls: safe cooldown, debris removal, trough clearing, or final verification. This template turns the closeout into a repeatable sequence with clear roles, expected outcomes, and photo evidence. That makes it easier to train new staff, audit performance, and reduce variation between shifts.
Can this SOP be integrated into a digital checklist or CMMS?
Yes. The steps map cleanly into a mobile checklist, a closing log, or a CMMS task with photo attachment and sign-off fields. You can add timestamps, station IDs, and escalation triggers for maintenance follow-up. If your operation uses ITIL-style runbooks for facilities or kitchen equipment, this template can function as the operational closeout record.
