Commercial cleaning is professional cleaning of non-residential buildings: offices, warehouses, hospitals, schools and other large facilities. It differs from home cleaning in scale, traffic, equipment and the rules a facility has to meet.
This guide draws on ISSA, the cleaning industry association, and on Nilfisk, a commercial cleaning machine maker. It covers what the work includes, where it happens and what crews use to do it.
- ISSA defines commercial cleaning as professional cleaning services for businesses, institutions and commercial buildings, handling larger spaces, higher foot traffic and stricter industry regulations than residential work.
- The service mix runs from routine janitorial work (dusting, trash removal, sweeping, mopping) through floor care such as stripping, buffing and waxing to specialty jobs like window washing, post-construction cleanup and pressure washing, per ISSA.
- Per ISSA, citing the U.S. Bureau of Labor Statistics, over 3 million janitors and building cleaners worked in more than 1.2 million businesses in 2023, mostly in small companies of under ten people.
- Nilfisk says commercial work usually needs larger teams, industrial-grade equipment and knowledge of sector-specific regulations.
What Is Commercial Cleaning?
Commercial cleaning is the professional cleaning of businesses, institutions and other non-residential buildings. ISSA describes it as professional cleaning services provided to businesses, institutions and commercial buildings, and Nilfisk as the cleaning of spaces such as offices, warehouses and hospitals that needs a trained team using specialized equipment and set protocols.
The phrase covers the work whether a contractor does it or the facility's own staff does. What makes it "commercial" is the building, not who holds the mop.
How Is Commercial Cleaning Different From Residential Cleaning?
Commercial cleaning deals with bigger buildings, more people and more rules. ISSA says commercial work handles more complex tasks because of larger spaces, higher foot traffic and strict industry regulations.
| Commercial cleaning | Residential cleaning | |
|---|---|---|
| Where | Offices, warehouses, hospitals, schools, hospitality venues | Houses, apartments, condominiums |
| Team and equipment | Larger teams, industrial-grade equipment | Compact, versatile, lightweight tools |
| Rules | Sector-specific regulations and protocols | Set around the homeowner's preferences and schedule |
The comparison follows Nilfisk's breakdown.
What Services Does Commercial Cleaning Include?
Three groups of work cover most of it. ISSA lists them as routine janitorial services, floor care and specialty cleaning, and notes that programs are customized to building size, use and industry requirements.
| Service group | Examples (per ISSA) |
|---|---|
| Routine janitorial | Dusting, trash removal, restroom cleaning, sweeping, mopping |
| Floor care | Carpet cleaning, floor maintenance, stripping, buffing, waxing |
| Specialty | Window washing, post-construction cleanup, pressure washing |
For a task-by-task, frequency-sorted version of the routine group, see the commercial cleaning checklist. For the floor care group, start with how to strip and wax a floor.
Where Is Commercial Cleaning Used?
Anywhere people work, learn, shop, heal or travel in a non-residential building. Nilfisk names offices, warehouses, hospitals, airport terminals, factory floors and hospitality venues, and says each setting has its own challenges that call for specific techniques and equipment.
That variety means one program rarely fits two buildings, so the routines and machines differ by site. ISSA also points to its GBAC STAR accreditation, which covers cleaning procedures, staff training, cleaning technology and chemical management for facilities that want a recognized standard.
How Big Is the Commercial Cleaning Industry?
It is large and made up mostly of small companies. ISSA reports, citing the Bureau of Labor Statistics, over 3 million janitors and building cleaners employed in more than 1.2 million businesses as of 2023, with industry revenue forecast to pass $108 billion in 2025.
ISSA adds that most commercial cleaning companies employ fewer than ten people. Labor and equipment are both listed by ISSA as pricing drivers; see commercial cleaning cost per square foot for published rates and the formula to benchmark your own.
The routine damp-mop product for daily hard-floor care. It is pH-neutral, low-residue and low-foam at label dilution, needs no rinse under normal conditions, and is labeled for mop or cleaning-system use on concrete, stone, ceramic, wood, laminate, marble, granite and terracotta. Test a hidden spot first. On a scrubber, look for foam in the recovery tank on the first fill, because foam pulled into the vacuum motor damages it.
What Equipment and Supplies Do Commercial Cleaners Use?
Machines for floors, plus the chemistry that goes in them. Nilfisk says commercial work demands industrial-grade equipment.
| Task | Example machine | What the listing states |
|---|---|---|
| Large open hard floors | Dapper Supply walk-behind floor scrubber | 20 in. brush, 31.5 in. squeegee |
| Small areas and tight spaces | Dapper Supply mini automatic floor scrubber | 15 in. brush, 17 in. squeegee |
| Carpet extraction | U.S. Products Pegasus Pro 500H | Dual-cord, heated, 12.5 gal, 50 to 500 PSI |
Browse floor scrubbers, carpet extractors and commercial vacuums. Wet work creates slip hazards, so keep walking surfaces clean and, to the extent feasible, dry per OSHA (29 CFR 1910.22(a)(2)), and schedule it after hours where you can.
Should You Hire a Provider or Clean In-House?
Hire when the scope or the standard is beyond your crew; clean in-house when you have steady, predictable work and the equipment to do it. ISSA lists four factors for choosing a provider: reputation and experience, certifications and training, willingness to customize the plan, and transparent communication on pricing, contracts and standards.
If you go in-house, the buying list is short: the right machine for your floor area, pads or brushes, a floor chemical sized to the machine, and a written checklist. Compare your own cost per square foot with published contract rates before deciding.
