What You’ll Need Before You Start Cleaning Factory Machinery

The work of cleaning factory machinery safely starts long before anyone picks up a tool. Get the prep wrong and you risk injury, damaged equipment, or a production line down for days. At Pure Steam Cleaners, we supply machines to manufacturers, food plants, and contract cleaners, and the same rule holds everywhere: preparation is the job.

You need five things in place first:

• The machine’s manual and its lock-off procedure
• Correct PPE: gloves, eye protection, and non-slip footwear
• Dry brushes, vacuums, and lint-free cloths for debris
• A suitable cleaning machine rated for industrial use
• A written risk assessment covering the task

A 2026 machine-safety review identifies a thorough risk assessment as the first step before selecting any cleaning method or device (Stronghold Safety’s machine safety trends). Skip it and you are guessing.

If you are unsure which machine suits your site, contact our team for advice before you buy.

Machinery Cleaning Safety Precautions You Cannot Skip

The most important safety precaution is isolation. Never clean a machine that can start, move, or release stored energy. Everything else follows from that.

Beyond lock-off, keep these rules in place:

• Keep the area around machinery clean, tidy, unobstructed, and well lit, as the International Labour Organisation’s machinery guidance advises
• Never reach into guarded areas, even with the power off
• Check for hot surfaces and let them cool before you start
• Keep water and steam away from electrical panels and control boxes
• Ventilate the area if you use any cleaning agents

Chemical exposure is a real concern. A 2024 review of machinery safety and training notes that operators need proper instruction before working with equipment (MDPI’s review of machinery safety and training). If you want to cut chemicals out entirely, our guide on how to switch to chemical-free cleaning sets out the steps.

Step 1: Isolate and Lock Off the Machine

Isolation is the step that keeps people alive. Lock off the machine at its isolation point, remove the key, and keep it with you. Test that the machine will not start before you go any further.

Follow this order:

1. Shut down the machine using its normal stop procedure
2. Isolate all energy sources: electrical, pneumatic, hydraulic
3. Apply your lock and tag
4. Release any stored pressure or energy
5. Try to start the machine to confirm isolation

Watch out: a common mistake is isolating the power but forgetting stored energy in rams, springs, or pressurised lines. That energy can move a component the moment you touch it.

Step 2: Dry-Clean Loose Debris First

Dry cleaning comes before any wet method. Remove loose dust, crumbs, swarf, and build-up with brushes and a vacuum. This stops debris turning into a paste that spreads contamination.

Work top to bottom so loosened material falls away from clean surfaces. Use a vacuum rated for the dust you are dealing with, especially in food plants where flour and sugar dust can be explosive.

A 2026 guide to industrial facility cleaning frames routine cleaning as part of safer, more efficient operations (Goodway’s industrial facility cleaning guide). Dry cleaning first is a big part of that. It cuts the wet work and reduces how much grime you have to shift later.

Step 3: Steam Cleaning Manufacturing Equipment

Steam cleaning is the most effective way to clean factory machinery without harsh chemicals. Dry steam lifts grease and residue from metal surfaces, then a vacuum pulls the loosened waste away.

Steam is particularly effective for removing stubborn residues, though specialised solvents are often required when cleaning industrial ink from delicate printing components.

Our heavy-duty machines suit this work. The Pure i8 produces steam at 8 bar with a 10-litre reservoir for over three hours of running time, and its 23-litre waste tank handles the extraction. The Pure i6-SV offers 6 bar and 53 g/min in a lighter body for tighter spaces. Both run on a standard plug and use very little water.

How to Remove Grease from Industrial Machinery

Grease removal comes down to heat and dwell time. Steam softens baked-on grease so it lifts instead of smearing. Hold the wand close, let the steam work for a few seconds, then wipe or vacuum.

For stubborn build-up:

• Steam in small sections rather than rushing the whole panel
• Give thick grease a second pass
• Use the vacuum to catch run-off before it spreads
• Wipe with a lint-free cloth while the surface is warm

If grease is your main problem, our page on steam versus built-up grease explains why heat beats chemical degreasers on heavy deposits.

Your Factory Equipment Cleaning Checklist

Use this factory equipment cleaning checklist to keep every job consistent. Print it and tick each line before the machine goes back into service.

• Risk assessment completed and briefed to the team
• Machine isolated, locked off, and tested
• Stored energy released
• PPE worn by everyone on the task
• Loose debris removed with brush and vacuum
• Guards and panels checked for damage
• Steam cleaning completed, section by section
• Waste and run-off extracted
• Surfaces dried and inspected
• Lock removed and machine restarted under supervision
• Cleaning logged with date and operator

How Often Should Factory Machinery Be Cleaned?

Most factory machinery needs a daily clean of contact surfaces, a weekly deep clean, and a full steam clean monthly. High-risk areas in food production may need more.

Set frequency by risk, not habit:

Area	Frequency	Method
Food contact surfaces	Every shift	Steam and vacuum
Conveyors and guards	Weekly	Dry clean, then steam
Grease-heavy drives	Monthly	Steam clean
Full machine deep clean	Quarterly	Full strip and steam

Hard water areas need extra care. Limescale shortens boiler life, so build descaling into your schedule. Our step-by-step guide on how to descale commercial steam equipment shows you how to spot limescale early and protect your machine.

Frequently Asked Questions

Can steam be used to clean industrial machinery?

Yes, dry steam is suitable for many factory machines, particularly stainless steel, conveyors and food-contact surfaces. It lifts grease and grime without harsh chemicals and uses very little water. Avoid direct steam on sensitive electronics, open bearings and any component the manufacturer says is not steam-safe. Always isolate the machine first and test on a small area. Steam cleaning manufacturing equipment works best when paired with vacuum extraction, which removes loosened debris rather than spreading it.

How do you remove grease from manufacturing equipment?

Start by scraping or wiping off loose grease, then apply dry steam at pressure to soften the residue. A machine with a detergent supply, such as the Pure i6-SV at £2,495.00, can handle stubborn areas where a specialist degreaser is needed. Work from the top down so runoff does not soil clean sections, and use the vacuum to capture loosened grease immediately. For heavy build-up, repeat in passes rather than holding the wand in one spot.

What checks should be made before restarting machinery after cleaning?

Confirm all guards and panels are refitted, no tools or cloths are left inside, and all electrical enclosures are dry. Check that lockout tags are removed only by the person who applied them, and that the machine is clear of people before power is restored. Run a short no-load test and listen for unusual noise. Record the restart in your maintenance log so the next clean can reference it.

How often should factory machinery be cleaned?

Frequency depends on the process and the risk. Food-contact surfaces are typically cleaned after every shift, while general plant and low-risk equipment may be cleaned weekly or monthly. Build the schedule from your risk assessment and the manufacturer’s instructions, then adjust if you see grease build-up or contamination between cleans. Document each clean in your factory equipment cleaning checklist so intervals stay consistent and auditable.
