Grease accumulates quietly inside canopies, plenums, duct runs and exhaust fans. Without kitchen extraction system cleaning, those residues harden into a flammable fuel layer that increases ignition risk, undermines hygiene, and impairs extraction performance. For hotels and restaurants, a specialist programme, covering kitchen canopy cleaning, grease duct cleaning and exhaust fan cleaning, helps you reduce fire load, stabilise airflow, and pass inspections with audit‑ready reporting and a clear compliance certificate.
Fire Safety and Hygiene in Commercial Kitchens
During every service, heat and aerosolised fats are captured at the canopy and drawn into the extraction path. Baffle filters remove part of this load, but fine particles pass through and deposit on the plenum, elbows, horizontals and fan housing. Over time this leads to:
- Elevated fire risk: deposits are readily ignitable by cookline flare‑ups, motor overheating, or sparks during maintenance.
- Restricted airflow: the system must work harder, increasing wear on motors and bearings.
- Hygiene issues: residue films trap odours and can contribute to non‑conformities during audits.
A proactive, evidence‑based cleaning plan brings the system closer to design performance and supports safer, cleaner kitchens.
What Proper Extraction System Deep Cleaning Includes
“Wipe‑downs” won’t satisfy auditors, or insurers. A compliant deep clean treats the entire air path from canopy to discharge:
- Survey & Access Planning
A trained team maps canopies, plenums, risers, horizontals, fan housings and discharge points; identifies blind spots; and specifies access door installation so critical sections can be reached safely. - Containment & Protection
Drip control and sheeting protect appliances and finishes. Where appropriate, sections are isolated and placed under negative‑pressure capture to prevent re‑entrainment of debris. - Mechanical Source Removal
- Baffle filter cleaning (soak/clean or replace)
- Plenum cleaning (heated, food‑safe degreasers; scraping of heavy deposits)
- Grease duct cleaning (sectional agitation/scraping along risers and horizontals)
- Exhaust fan cleaning (blade and housing degreasing; clear drains; check free rotation)
- Baffle filter cleaning (soak/clean or replace)
- Rinse, Neutralise & Reassemble
Surfaces are rinsed and neutralised; access doors are re‑sealed; drains and bearings are checked; the fan is returned to service. - Verification & Reporting
The team documents before/after photographs, records observations on grease levels, and issues a compliance certificate with recommended intervals.
This engineered method converts “we think it’s clean” into defensible proof.
Our Deep Cleaning Services for Hotels and Restaurants
Hospitality operations need a solution that protects service windows and stands up to scrutiny. Concept Clean Africa delivers:
- Full‑path cleaning: canopy → plenum → ducts → fan → discharge
- Out‑of‑hours works to protect service and revenue
- High‑level access capability for long risers and rooftop fans
- Audit‑ready reporting: photos, access maps, findings and interval guidance
The goal is a clean, efficient, verifiably safe system, without disrupting your trading day.
Documentation That Satisfies Inspectors and Insurers
Maintain a compliance file that includes:
- A dated service certificate describing scope and any temporarily inaccessible sections (with reasons)
- Before/after photography of canopies, representative duct sections and the fan
- An access door map to streamline future maintenance
- A recommended cleaning interval tailored to your menu and production volume
This pack evidences control of a known risk and helps avoid disputes with insurers.
Scheduling and Downtime, Keep Operations Moving
We design programmes that respect kitchen rhythms:
- Overnight or dark‑kitchen slots to avoid lost covers
- Phased works for multi‑kitchen sites so at least one line stays open
- Filter exchange between deep cleans to preserve capture efficiency
- Clear start‑up/shut‑down procedures for fans and electrics
With proper staging, even complex duct runs can be cleaned with minimal operational impact.
How Often Should You Clean?
Intervals depend on production volume, menu, duct geometry and housekeeping discipline:
- Heavy use (frying/grilling): every 1-3 months
- Moderate use: every 3-6 months
- Light/seasonal: annually, with periodic inspections
Adjust based on verification photos and observed grease rates, shorten intervals when volumes or menus change.
The Cost of Skipping Deep Cleaning
- Smoke rollback and odour in work or guest areas
- Higher energy draw as fans fight restriction
- Accelerated wear on motors and bearings
- Compliance exposure without audit‑ready reporting
Preventable issues compound quickly; cleaning is far cheaper than downtime and damage.
