Industrial Paint Booth Cleaning. Certified Crews. Minimal Downtime.
Paint booth buildup is a fire hazard, a compliance violation, and a drag on finish quality. iSi's certified crews clean industrial paint booths for manufacturers nationwide — fixed pricing, most jobs completed in a single shift.
The Booth That Almost Burned Down
A Midwest manufacturer ran three downdraft booths for seven years without professional cleaning. Overspray buildup in the exhaust plenum exceeded two inches. During a routine production run, a spark from a contaminated filter ignited the accumulated residue. The fire suppression system activated, but the booth was offline for three weeks. Insurance covered the equipment — not the $340,000 in lost production, the OSHA inspection that followed, or the two-year increase in fire insurance premiums.
The professional cleaning that would have prevented it: roughly $8,000 per booth per year.
What Paint Booth Cleaning Includes
Every booth cleaning follows the same scope framework — adapted to your booth type, size, and paint chemistry.
Walls, Ceiling & Floor
Full interior scraping and cleaning of all booth surfaces. Overspray residue removed from walls, ceiling panels, and floor grates. For downdraft systems, pit cleaning is included.
Plenum & Exhaust Ducts
Exhaust plenum cleaning and duct scraping. This is where the heaviest accumulation builds and where booth fires typically start. Returned to clean, unobstructed airflow.
Filters & Airflow
Filter inspection and replacement coordination. Light fixture and diffuser cleaning. Airflow balance verification after cleaning to confirm booth performance is restored.
Waste Disposal
All collected overspray and residue is properly packaged, manifested, and disposed of in compliance with applicable waste regulations. No residue left on site.
Documentation
Post-cleaning report documenting scope completed, booth condition before and after, and any observations about filter condition, airflow issues, or maintenance needs. Useful for compliance records and insurance documentation.
Scheduling
iSi schedules around your production calendar. Most clients schedule during planned shutdowns or between shifts. Single-booth jobs typically complete in one shift. Multi-booth facilities: 2-5 days depending on scope.
The Compliance Math: What Skipping Cleaning Actually Costs
Paint booth cleaning is required under OSHA 1910.107, OSHA 1910.94, and NFPA 33. These aren't suggestions — they're enforceable standards. But the real cost of skipping cleaning isn't the citation. It's everything else.
The cleaning pays for itself in reduced rework alone for most high-volume operations. Add the fire risk reduction and OSHA compliance, and it's one of the simplest ROI calculations in facility maintenance.
What Happens Around Booth Cleaning
The cleaning itself is about 40% of the compliance picture. The other 60% is what goes wrong when you don't have the right team doing it.
Filter management. Waste manifesting. Air permit documentation. Post-cleaning airflow verification. Insurance documentation that proves your booth was maintained. Coordination with your production schedule so the booth is down when you can afford it.
Because iSi also provides industrial hygiene, environmental compliance, and air permitting services, your booth cleaning plugs into a broader compliance program. If your booth operation triggers air permit requirements, iSi's consulting division handles that too — same company, same point of contact. No separate vendor for the environmental side.
Booth Types We Clean
Downdraft
Air flows top-to-bottom through floor grates. Includes pit cleaning, plenum access, and exhaust duct scraping.
Crossdraft
Air flows horizontally from intake to exhaust. Wall and filter bank accumulation is the primary concern.
Semi-Downdraft
Hybrid airflow — intake from ceiling, exhaust from rear wall. Cleaning covers both ceiling-mounted intake and rear exhaust systems.

Paint Booth Cleaning Questions
How often should paint booths be professionally cleaned?
OSHA 1910.107 and NFPA 33 require routine cleaning of spray booths to prevent hazardous accumulation of overspray residue. The frequency depends on your production volume, paint type, and booth configuration. High-volume operations may need quarterly cleaning; lower-volume facilities may clean annually. If you can see buildup on walls, plenums, or exhaust ducting, you're overdue.
What does professional paint booth cleaning include?
Full interior scraping and cleaning of walls, ceiling, and floor grates. Plenum and exhaust duct cleaning. Filter replacement coordination. Light fixture and diffuser cleaning. Booth pit cleaning for downdraft systems. Proper disposal of collected overspray waste. The booth is returned to production-ready condition.
How long does paint booth cleaning take?
Most single-booth cleaning jobs complete in a single shift. Multi-booth facilities with heavy buildup may require 2-5 days depending on booth count, size, and condition. iSi schedules around your production calendar — many clients schedule during planned shutdowns or shift changes.
Does iSi clean all types of paint booths?
Yes — downdraft, crossdraft, and semi-downdraft paint booths of all sizes, from single-bay automotive booths to large aerospace and industrial coating booths exceeding 40 feet. Crews handle urethane, epoxy, polyester, waterborne, and powder coat applications.
What are the OSHA and fire code requirements for paint booth cleaning?
OSHA 1910.107 (Spray Finishing) requires spray booths be kept free from combustible residue deposits. OSHA 1910.94 covers ventilation. NFPA 33 requires regular cleaning and maintenance of spray areas and exhaust systems. Violations can result in citations starting at $16,550 per instance — but the real exposure is fire risk and lost production.
Does iSi travel nationwide for paint booth cleaning?
Yes. Crews travel nationwide. Mobilization costs are hotel and per diem only — no travel markup on labor rates. Multi-booth facilities and repeat clients can set up scheduled cleaning programs that reduce per-visit cost.
