A commercial kitchen usually has two very different cleaning problems. The burners, hoods and floors need scrubbing, and the pipework above and behind them needs a plan nobody thinks about until a leak appears. Pipe exteriors collect a film of cooked-on grease and airborne oil that ordinary wiping only smears. Before any cleaning begins, walk the kitchen and write down what you actually have.
1. A pipe map you can stand on
Start with a simple drawing of the exhaust duct runs, water supply lines, drain lines and any gas piping, showing what is above the cookline, above the prep area, in the wall chase and in the ceiling void. Mark the access panels, the shut-off valves and the points where pipes pass through a wall. Note which lines are hot and which are cold, and where condensation forms. If the kitchen has a fixed steam cleaning machine already assigned to the site, record where its power supply reaches, since an outlet that exists in the prep area may not exist at the far end of the cookline.
2. What the coating on the pipe actually is
Name the soil before you choose a method. A sticky, soft film that has formed in weeks behaves differently from a hard, dark lacquer that has been baking on a duct for a year. Grease near a hood is usually thicker and older than grease on a water pipe two metres away, and the pipe material matters too: stainless steel, galvanised steel and painted steel tolerate different treatment. Record pipe material, diameter, insulation and whether the surface is reachable by hand or only by a ladder and a long tool. That detail decides whether your crew works from the floor, from a platform, or needs a machine with a lance and hose long enough to cover the run.
3. Access, clearance and safety
Measure the gap between the pipe and the wall, and the height of the working platform. Note any insulation that has to be removed and refitted, and any drip or condensate that could reach an electrical fitting. List the isolations you need: hot water, and any electrical equipment near the work area. Confirm what may be sprayed near electrical panels and light fittings, and confirm what the local fire authority requires for duct work, since a cleaning plan that blocks the kitchen for the wrong hours costs more than the cleaning itself. Decide who supervises the work, who moves equipment out of the way, and how the kitchen keeps serving during the shift.
4. Method and equipment on the list
For overhead pipework, hot water under pressure removes a built-up grease film far faster than a bucket and a rag. The PowerDe HW02 steam cleaner is a fixed 220 V unit with a 6 kW heater and an 80 L tank, which means a crew can work along a long pipe run without running back for water every few minutes; its dry-steam setting suits surfaces where a soaking wet rinse would drip onto the line below. For kitchens where the pipe route changes between buildings or the machine has to travel, commercial steam cleaning equipment in a mobile format is worth comparing instead. Write down which machine, which nozzle, which hose length, and what happens to the run-off.
5. Containment and drainage
Grease-heavy water cannot be allowed to fall onto a cooking surface or run across a serving area. Note where the run-off will land, which floor drains are nearby, and whether a strainer is needed so solids do not enter the drain. Check whether the local water authority has rules for that discharge in your area and record it in the plan. Skirting, drainage trays and a method for collecting what falls off a vertical pipe belong in the assessment, because they change the labour estimate more than the cleaning itself.
6. Drying, inspection and sign-off
A wet pipe above a cold area keeps dripping long after the crew has left. Plan for ventilation, a wiping pass, or a dry-steam finish, and state how long the area stays closed. Then define how the job is judged: which runs are checked, from where, against a photograph taken before the work, and who signs the sheet. A short re-inspection after the kitchen has been running for a shift shows whether the coating came off or was simply pushed into the insulation.
7. Frequency and the next assessment
A kitchen that grills and fries all day builds up a heavier coating than one that only reheats. Set the next cleaning interval from what you found this time, and keep the pipe map current whenever equipment is moved or a duct run is extended. When a site changes hands, or when you are quoting a kitchen you have never worked in, send someone to walk it and repeat the assessment rather than copying the old sheet.
