DIY vs Professional Kitchen Exhaust Cleaning
Some exhaust cleaning is everyday kitchen work; some needs trained contractors, access equipment and safety planning. Here is where the line usually sits.
By Apex Commercial Exhaust · · 5 min read
Key takeaways
- Staff can usually handle filters, gutters, drip trays and exterior wipe-downs.
- The plenum, ducts and rooftop fan need trained contractors with access and safety planning.
- Never enter ducts, climb onto roofs or work on energised equipment.
- Degreasers are hazardous chemicals; follow the label and safety data sheet.
- Combine daily DIY tasks with periodic professional cleaning of the whole system.
Many kitchens try to save money by cleaning the exhaust themselves. Some of the work is perfectly suited to trained staff; some of it is not. Here is a practical split.
What staff can do vs what needs a professional
| Part | Staff (DIY) | Professional |
|---|---|---|
| Grease filters | Clean or swap on schedule | Exchange programs, deep cleaning |
| Canopy exterior | Daily wipe-down | Detailed degreasing |
| Gutters & drip trays | Empty and wipe | Clean channels and blockages |
| Plenum | Not recommended | Degrease behind filters |
| Ducts | Never enter | Clean through access points |
| Rooftop fan | Never go on the roof | Isolate, clean, note concerns |
Why ducts and fans are not DIY jobs
Duct and fan cleaning usually involves working at height, isolating equipment and handling strong degreasers. In Victoria, falls from height are covered by Part 3.3 of the OHS Regulations 2017; other states follow codes like Safe Work Australia’s falls code. Degreasers should be managed using their safety data sheets (hazardous chemicals code).
The hidden cost of DIY
DIY cleaning tends to stop at what is visible. Grease left in the plenum, ducts and fan keeps building up, and there is usually no record of what was cleaned. When a landlord, insurer or inspector asks, it is hard to show the work was done. See what records to keep.
DIY vs professional: the best of both
Use a simple staff routine for filters and surfaces (checklist) and book periodic professional cleans for the whole system. Within the agreed scope, Apex cleans all accessible and reachable areas of the kitchen exhaust and provides photos where included.
Frequently asked questions
Can I clean my restaurant exhaust hood myself?
Staff can clean filters, gutters and exterior surfaces following site procedures. The plenum, ducts and fan need trained contractors.
Is it cheaper to clean the exhaust in-house?
Daily tasks in-house save time and money; but grease left in hidden areas keeps building up, which can make later cleans bigger.
What equipment do professionals use?
Suitable degreasers, scrapers, brushes, protection for the kitchen, and access equipment for ceilings and roofs.
