Eco-Friendly Cleaning: How to Choose Products and Use Them

Federal law does not require cleaning-product makers to list every ingredient; only EPA-registered disinfectants must declare their active ingredients. California's Cleaning Product Right to Know Act (SB 258, 2017) requires online and on-label disclosure for products sold there, which is why many labels have improved. Even so, the single word "fragrance" can still stand for several components that are not itemized.

"Natural" and "non-toxic" are advertising claims: under the FTC's Green Guides a seller must be able to substantiate them, but the words alone don't tell you whether a product suits your surface or your household. What does: the ingredient list, any EPA logo, the signal word, and the directions.

The most useful logo on a cleaner is EPA Safer Choice. To carry it, every intentionally added ingredient is reviewed against EPA's criteria for human health and the environment, the product must pass performance testing for its category, and it must meet limits on VOCs and packaging. Antimicrobial products cannot carry Safer Choice; the equivalent review for registered disinfectants is EPA's Design for the Environment (DfE) logo. Neither logo means a product is risk-free, and neither replaces the directions on the label. EPA also notes that a "natural" origin does not by itself mean lower risk.

Cleaning, sanitizing and disinfecting are different claims. Only an EPA-registered product can be labeled as a sanitizer or disinfectant, and only for the organisms and contact time on its label — look for the EPA registration number. A general-purpose plant-based cleaner cleans; it does not disinfect. Plant-derived surfactants lift soil the same way petroleum-derived ones do; where an ingredient comes from is not a guarantee of zero residue. Wiping, rinsing and drying as the label directs is what leaves a surface clean.

Ventilation matters as much as the product. The EPA's guide to indoor air quality notes that indoor levels of some pollutants may be 2 to 5 times higher than outdoor levels and lists household cleaning products among the sources of indoor VOCs, which linger longest in poorly ventilated rooms such as bathrooms.

Children breathe more air for their body weight than adults, crawl on floors, and put their hands in their mouths. Pets walk on cleaned floors and groom by licking. Whatever is left on a floor — dust, residue, a product that was not wiped up — reaches them more directly than it reaches an adult. That does not mean a given product has harmed a child or a pet; it means wiping, drying and re-entry directions on the label matter more in those homes.

Two observational studies are worth knowing. In the Canadian CHILD birth cohort, Parks et al. (CMAJ, 2020) found that infants in homes with frequent use of household cleaning products had a higher risk of recurrent wheeze and asthma by age 3. In adults, Svanes et al. (AJRCCM, 2018) associated regular cleaning at home, especially with sprays, with faster decline in lung function over 20 years. Both are associations, not proof that any product causes disease, and neither says anything about a particular cleaning service.

For pets, the ASPCA Animal Poison Control Center lists household cleaners among common hazards and singles out pine-oil (phenol) products — often marketed as natural — and chlorine products as concerns, cats in particular. Keep pets out of the room while any strong product is used, ventilate, and follow the label's re-entry directions rather than relying on the smell fading.

Before a visit, tell us about infants, pets, allergies or fragrance sensitivities so the team can plan the order of rooms and drying times around them. Your pediatrician or veterinarian is the right source for a specific child or animal.

Montgomery County, Washington DC and Northern Virginia sit inside the Chesapeake Bay watershed. According to the Chesapeake Bay Program, the watershed covers about 64,000 square miles across parts of six states and all of DC, and excess nitrogen and phosphorus — mostly from agriculture and stormwater — are the main drivers of its water-quality problems. A household's share is small, but it is the share a household controls.

What a home can do is on the label: use the dilution and quantity it calls for, follow its disposal directions, never mix products, and never pour concentrates down a drain or into a septic system. "Readily biodegradable" is a label claim about the surfactant, not a promise about how any treatment plant or septic system performs. Where a product does not state disposal directions, your county's household hazardous waste program is the right place to ask.
