The EPA reports that indoor concentrations of volatile organic compounds run two to five times higher than outdoor levels — and it lists cleansers and disinfectants among the household and commercial products that release them.
That’s an uncomfortable fact for anyone buying cleaning services. The products meant to make a building healthier can quietly work against it, especially in offices and facilities that run sealed up for months at a time.
Green janitorial services exist to close that gap. Not by cleaning less thoroughly, but by choosing products and methods that get the same result without loading the air with what caused the problem.
We clean commercial buildings for a living, and eco-friendly products have been our default for years. Here’s what actually changes when a building switches, what to look for in a provider, and where “green” claims tend to fall apart.
What Makes a Cleaning Program Actually Green
The term gets used loosely. A vendor who swapped one product for a bottle with a leaf on the label is not running a green program.
A real one covers four things:
- Product selection. Biodegradable, low-VOC formulations with third-party certification behind them rather than marketing language.
- Dilution and application. Using the right amount. Over-application is one of the most common ways a green product stops being green.
- Equipment and process. Microfiber instead of disposables, HEPA filtration in vacuums, equipment that uses less water and power.
- Waste handling. Reusable materials, concentrate refills instead of single-use bottles, and recycling built into the routine.
Miss any one of those and the other three do less than you’d think. A certified product applied too heavily in an unventilated room is still a problem.
Pro Tip: Ask a prospective vendor what their dilution process looks like. If the answer involves someone eyeballing it from a jug, the product certification on the label is doing less work than you’d hope.
What Changes for the People in the Building
This is the part that matters most to the businesses we work with, and it shows up faster than people expect.
- Fewer airborne irritants. Conventional cleaners release VOCs that can cause eye, nose, and throat irritation, headaches, and nausea. Switching products removes a recurring source.
- Better conditions for people with asthma. Cleaning-product fumes are a recognized asthma trigger. In a building with any meaningful number of occupants, some of them are affected.
- Less residue on surfaces people touch. Desks, handles, and shared equipment stop carrying a film of whatever was sprayed on them.
- No lingering chemical smell. Often the first thing clients notice, and the thing their employees comment on.
Worth being straight about: nobody should promise that green cleaning cures anything. What it does is remove an avoidable source of irritation from a space where people spend most of their waking hours.
The Ventilation Problem Nobody Mentions
Buildings in cold climates run sealed from late autumn through early spring. Whatever goes into the air stays there.
That’s precisely when conventional products do the most damage, and precisely when most cleaning contracts don’t change anything about their approach. If your building is closed up for months, product selection stops being a preference and starts being the main lever you have over indoor air.
Clean, Disinfect, and Why the Order Matters
Green or conventional, this is the part most crews get wrong — and getting it right often means using less product, not more.
Step | What it does | When you need it |
Clean | Soap or detergent and water lifts away soil, oils, and residue | Always first — dirt physically shields germs from whatever comes next |
Disinfect | An EPA-registered product kills germs left on the surface | High-touch hardware, restrooms, and after illness in the building |
The CDC’s guidance for offices and community facilities makes the same point: clean first, because impurities make disinfectants less effective.
Here’s why that matters for a green program. Disinfectants are the harshest products in any cleaning cart. A crew that cleans properly needs to disinfect fewer surfaces, less often — which reduces chemical load without reducing hygiene. Crews that skip cleaning tend to compensate by disinfecting everything, constantly.
Pro Tip: Disinfectant doesn’t belong on every surface in a building. Routine cleaning handles most of it. If a vendor’s plan has them disinfecting every square foot daily, that’s not a thorough program — it’s an expensive one that’s harder on your air.
The Certifications Worth Checking
Anyone can call a product green. Third-party certification is the only part of the claim that’s been checked by someone with no stake in selling it.
Certification | What it covers | Why it matters |
Every ingredient reviewed against safety criteria, with performance testing | Federal program, searchable product database, hard to fake | |
Health, environmental, and performance standards across the product lifecycle | Long-established nonprofit, widely recognized in commercial cleaning | |
UL ECOLOGO | Multi-attribute lifecycle standards for cleaning products | Common in institutional and government purchasing |
ISSA CIMS with Green Building designation | Certifies the provider’s management systems, not just products | The only one that evaluates how a company operates |
That last row is the one most buyers overlook. Product certifications tell you what’s in the bottle. CIMS tells you whether the company using it has the training and processes to apply it properly.
Pro Tip: Ask for Safety Data Sheets — SDS — for anything used in your building. A vendor who can produce them quickly is a vendor who keeps track of what their crews carry. If someone still calls them MSDS, that terminology was retired over a decade ago, which tells you something about how current their training is.
What It Costs
The honest answer is that green cleaning is roughly cost-neutral over a full contract, and the reasons are more specific than “it pays for itself.”
Where it costs more:
- Certified products often carry a higher unit price than commodity chemicals.
- Switching mid-contract means retraining and sometimes new equipment.
Where it costs less:
- Most certified products are concentrates, so the per-use cost lands closer than the shelf price suggests.
- Microfiber replaces a recurring spend on disposables and lasts through hundreds of washes.
- Fewer products in the closet means less waste from expiry and overbuying.
- Properly diluted product gets used at the rate it was designed for, which is usually less than crews pour by habit.
Where the real money is:
Floors, fixtures, and surfaces last longer under a correct cleaning regimen than under an aggressive one. Harsh chemistry degrades finishes. Replacing flooring early costs more than any difference in product pricing across the life of a contract.
Pro Tip: When comparing quotes, ask what’s included in the product line rather than just the monthly number. A cheaper bid that burns through finishes is more expensive by year three.
How to Choose a Green Janitorial Provider
Most of the evaluation is the same as hiring any commercial cleaner. These are the questions specific to a green program:
- Which certifications do your products carry? You want names — Safer Choice, Green Seal, ECOLOGO — not “eco-friendly.”
- Can you provide SDS for everything used in our building? A good vendor says yes without hesitating.
- How do you handle dilution? Listen for dispensing systems and training, not estimates.
- What do you use for disinfecting, and on which surfaces? The answer should be “specific surfaces,” not “everywhere.”
- Do you use microfiber, and how is it laundered and separated? Color-coding between restrooms and other areas is the baseline.
- What’s your approach when a client has someone with chemical sensitivities? Tests whether they can actually adapt.
- Will you document what was used and when? Useful if anyone ever raises an air quality complaint.
If you’re evaluating vendors more broadly, our guide to hiring local business cleaning services covers the general process.
How We Handle Green Cleaning
Eco-friendly products are our default rather than an upgrade we sell. We use natural products including vinegar-based solutions as a baseline, and when a job needs a stronger disinfecting agent or calcium removal, we ask first rather than reaching for it automatically.
That conversation matters more than the product list. A medical clinic and a daycare have genuinely different requirements, and both differ from an office — our medical and clinic cleaning and daycare cleaning work runs on tighter product rules than a standard commercial account.
What we bring to any account:
- Background-checked, trained staff, briefed on confidentiality and privacy before entering a client facility.
- $5,000,000 commercial general liability coverage. We’re bonded and insured — ask any vendor for a certificate before they start.
- A signed checklist on every visit, so you have a record of what was done.
- Two-hour response and a 24-hour re-clean guarantee. If something’s missed, we fix it within a day at our cost.
- Month-to-month terms. No long contract.
- 24/7/365 scheduling, which also means product application happens when the building is empty.
Offices, break rooms, and shared common areas fall under our janitorial cleaning services, and larger buildings fit our facilities cleaning scope.
We serve businesses across Minneapolis, St. Paul, and the surrounding metro from our office in Edina — see our service areas. Call (952) 683-0955 or request a free estimate, and we’ll walk your building, look at what’s being used now, and show you what would change.
Frequently Asked Questions
What are green janitorial services?
Green janitorial services use certified low-toxicity cleaning products, reusable materials like microfiber, and equipment that reduces water and energy use — while meeting the same cleanliness standards as conventional commercial cleaning. The difference is in product selection, dilution control, and waste handling rather than in how thoroughly the work gets done.
Are eco-friendly cleaning products as effective as conventional ones?
For routine cleaning, yes. Certified products are performance-tested, not just screened for safety. Where a genuine disinfectant is required — restrooms, high-touch hardware, after illness — you still need an EPA-registered product, and a good green program uses one on those specific surfaces rather than treating the whole building.
Does green cleaning cost more?
Over a full contract it tends to be close to cost-neutral. Certified products often cost more per bottle but most are concentrates, microfiber replaces recurring spend on disposables, and gentler chemistry extends the life of floors and fixtures. The upfront switch can cost more if it means retraining or new equipment.
What certifications should I look for in a green cleaning company?
EPA Safer Choice and Green Seal are the most recognized product certifications, with UL ECOLOGO common in institutional purchasing. ISSA’s CIMS with Green Building designation certifies the provider’s own management systems rather than their products, which is the one that tells you whether a company can apply those products properly.
Can green cleaning improve indoor air quality?
It removes one recurring source of indoor air pollution. The EPA lists cleansers and disinfectants among the products that release volatile organic compounds, and reports indoor VOC concentrations running two to five times higher than outdoor levels. Lower-VOC products reduce that load, which matters most in buildings that run sealed through winter.
Is green cleaning better for people with asthma or allergies?
Cleaning-product fumes are a recognized asthma trigger, so reducing VOC exposure generally helps. It won’t resolve an underlying condition, and anyone with a diagnosed sensitivity should talk to their own clinician. What a building owner controls is whether the cleaning program is adding to the problem.
Where to Start
You don’t need to overhaul a contract to find out whether this matters in your building. Ask your current provider for a list of what they use and the SDS for each one.
That single request tells you most of what you need to know. A vendor who sends it the same day is tracking their chemistry. A vendor who can’t is probably not managing dilution either — and that’s the gap where a green program either works or doesn’t.
