What industrial cleaning covers: from production lines to silos
Updated
Industrial cleaning is a label covering half a dozen genuinely different trades. Knowing which one you are buying is the difference between three comparable quotes and three quotes for three different jobs.
The main types of work
- Production line and machinery cleaning
- Cleaning plant, conveyors, guarding, mixers and process equipment, usually during a shutdown, often with isolation and permits. The variables are residue type, how much dismantling is needed, and whether the contractor or your engineers break down the equipment.
- High level cleaning
- Roof structure, beams, cable trays, lighting, sprinkler heads and ductwork. Bought for dust control, fire risk, light levels and hygiene audits. Priced on access method far more than on area.
- Tank, silo and vessel cleaning
- Internal cleaning of storage and process vessels, pits and sumps. Frequently a confined space entry, and priced as a specialist operation with gas monitoring, rescue cover and a permit to work.
- Post-construction and handover cleaning
- The clean that turns a finished build into a usable space: construction dust, protective films, adhesive residue, sanitary and glazing finishing. Scheduled tightly against a handover date, which is itself a cost driver.
- Spill and contamination response
- Reactive attendance for a product release, oil spill or contamination event, including containment, recovery, decontamination and disposal of the arisings. Priced reactively and usually out of hours.
- Extract and ductwork systems
- Process extract, dust extraction and ventilation ductwork. Kitchen extract systems are a separate specialism with their own standards and are normally bought from firms that do only that.
What contractors need to know before they can price
- What the residue is. Dust, oil, carbon, product, flour, resin and biological soiling all clean differently and need different chemistry.
- How high, and how you get there. Ground level, platform, tower, rope access or reach and wash decides the crew and the equipment.
- Whether anyone has to enter anything. Tanks, silos, pits and vessels move the job into a different category entirely.
- What window exists. A shutdown date, a night, or a rolling programme around production.
- Where the water and waste go. Effluent restrictions, interceptor capacity and waste classification shape the method before the price.
How to write an enquiry that gets comparable quotes
- Name the work type from the list above rather than asking for a deep clean, which means different things to different contractors.
- State the area and the soiling in plain terms, with photographs if you can. Photographs of a dirty beam save two site visits.
- Give the window and the constraints, including permit systems, hygiene standards and anything that must stay running.
- Ask for the same scope from everyone. Send one written scope to each contractor, and the quotes become comparable for free.
Where the job includes confined space entry or work at height, treat it as a separate conversation rather than a line in a cleaning quote. Our guide to confined space and high level cleaning explains what changes and what to ask the contractor to confirm.
