What’s Involved in a Commercial Kitchen Deep Clean?
Jul 03, 2025
If you run a restaurant, café, or food preparation facility, cleanliness isn’t just about appearance—it’s a matter of health, safety, and compliance. A spotless commercial kitchen is essential for passing health inspections, protecting your staff and patrons, and maintaining your business's reputation. That’s where a professional deep clean comes in.
Unlike daily surface-level cleaning, a commercial kitchen deep clean is thorough, technical, and detail-driven. It targets areas that are easily overlooked during routine maintenance and removes the build-up of grease, grime, and bacteria that can lead to serious issues if left unchecked.
Let’s break down exactly what’s involved in this intensive process.
1. Degreasing Walls, Floors, and Ceilings
Commercial kitchens are hotspots for airborne grease and moisture, which tend to settle on walls, floors, and even ceilings over time.
Industrial degreasers are applied to break down tough grime
Scrubbing and steam-cleaning ensure total removal of residue
Special attention is given to high-traffic and high-heat areas
These surfaces may look clean at a glance but can harbor layers of hidden buildup that increase the risk of fire and bacteria growth.
2. Deep Cleaning of Kitchen Equipment
Professional cleaners don’t just wipe down stoves and fryers—they take apart and clean equipment thoroughly, inside and out.
Ovens, grills, deep fryers, and steamers are dismantled where needed
Burners, trays, and filters are soaked and scrubbed
Exteriors and interiors are degreased and sanitized
This step extends the life of your equipment and improves performance by removing clogs and baked-on residue.
3. Exhaust Hoods and Ventilation Systems
Grease and smoke accumulate quickly in your ventilation system, posing fire and health hazards if not properly cleaned.
Exhaust hoods are scrubbed and polished
Grease filters are removed and soaked
Ductwork is inspected and cleaned to code
This is one of the most critical—and often legally required—components of a kitchen deep clean, particularly for fire prevention and air quality.
4. Sanitizing Prep Surfaces and Food Contact Areas
Even if surfaces look clean, they can harbor bacteria invisible to the eye.
Worktables, cutting boards, and countertops are disinfected with food-safe products
Undersides and corners are scrubbed to remove trapped debris
Sinks and splashbacks are descaled and sterilized
This process ensures all food-contact surfaces meet health code requirements and reduces the risk of cross-contamination.
5. Cleaning Cold Storage Units
Refrigerators, freezers, and walk-ins are deep cleaned to prevent mold, odors, and spoiled inventory.
Shelving and bins are emptied, cleaned, and sanitized
Fans, gaskets, and door seals are scrubbed
Mold and mildew are treated with specialized solutions
Professionals also check for ice buildup and airflow issues that can affect storage efficiency.
6. Floor Drain and Grease Trap Maintenance
Floor drains and grease traps can be breeding grounds for bacteria and foul odors if neglected.
Drains are flushed and cleared of debris
Grease traps are pumped out and sanitized
Cleaning agents are used to eliminate odors and bacteria
This is an essential part of maintaining kitchen hygiene and preventing costly plumbing issues down the road.
7. Final Sanitization and Detailing
The deep clean ends with a comprehensive walkthrough to ensure no area is missed.
Door handles, light switches, and shelving units are wiped down
Disinfectant fogging or steam cleaning may be used for final sanitization
A final inspection ensures the kitchen meets all hygiene standards
This ensures every inch of your kitchen is clean, safe, and ready for the next health inspection—or a busy dinner rush.
Conclusion
A commercial kitchen deep clean is an intensive, methodical process designed to tackle the grease, grime, and bacteria that everyday cleaning can’t reach. It helps protect your business from health code violations, fires, and equipment failures—while creating a safer, healthier environment for your staff and patrons.
