Cleaning products are a major source of indoor air pollution. The EPA has found that indoor VOC concentrations during cleaning activities can be 100x higher than outdoor levels. The irony: the products you use to clean your home are also contaminating its air.
Most of the damage is from three sources: synthetic fragrance (a cocktail of undisclosed VOCs), quaternary ammonium compounds ("quats") — linked to asthma and reproductive harm — and chlorine-based disinfectants that react with organic matter to form chloroform and other disinfection byproducts.
What to Avoid in Conventional Cleaners
- Quaternary ammonium compounds (quats): Used as disinfectants in many antibacterial products. Linked to asthma development in cleaning workers. The Safe Chemicals Coalition has flagged quats as a priority concern. Common names: benzalkonium chloride, benzethonium chloride.
- Glycol ethers: Solvents in many multi-surface sprays. Linked to reproductive harm and red blood cell damage at high concentrations. Common ones: 2-butoxyethanol, EGPE.
- Synthetic fragrance: Cleaning product fragrances contain VOCs including limonene (which reacts with ozone in indoor air to form formaldehyde), linalool, and various terpenes. "Fresh" smelling cleaners are often significant VOC sources.
- Bleach (sodium hypochlorite): Effective disinfectant, but releases chlorine gas at low concentrations, reacts with ammonia to form chloramines, and reacts with organic matter to form trihalomethanes including chloroform. Use in well-ventilated spaces only, and never mix with other cleaners.

Several simple formulations handle most cleaning tasks effectively:
- General surface cleaner: Mix 1 part white vinegar with 1 part water. Add a few drops of tea tree oil for mild antimicrobial properties. Note: don't use on natural stone (marble, granite) — vinegar etches the surface.
- Tough scrubbing: Baking soda paste (baking soda + water) is a gentle abrasive for bathroom grime and stovetop buildup. Bar Keepers Friend (oxalic acid) handles tough mineral deposits and rust without toxic ingredients.
- Glass and mirrors: Straight white vinegar in a spray bottle, wiped with a microfiber cloth — streak-free without commercial glass cleaners.
- Laundry: Washing soda + borax + castile soap — effective fragrance-free laundry powder at a fraction of the cost of commercial detergents.

Frequently Asked Questions
What cleaning products are most toxic?
The most concerning conventional cleaning products include bleach-based cleaners, ammonia-based cleaners, drain cleaners with sodium hydroxide or sulfuric acid, oven cleaners with lye, and many multi-surface sprays containing glycol ethers and synthetic fragrances linked to respiratory irritation and endocrine disruption.
Does "natural" mean non-toxic for cleaning products?
"Natural" is an unregulated marketing term in the cleaning product industry. Some "natural" brands use plant-derived ingredients that are still sensitizers or allergens. Check EWG's Guide to Healthy Cleaning for specific product ratings rather than relying on front-of-package claims.
Does Branch Basics actually clean effectively?
Branch Basics concentrate cleans effectively for everyday household tasks — general surfaces, laundry, dishes, bathrooms. Its plant-based surfactant blend is EWG A-rated. For heavy-duty jobs like drain clearing, specific non-toxic alternatives (baking soda + vinegar for drains, Bar Keepers Friend for tough stains) may be needed.
Is vinegar effective as a cleaner?
Diluted white vinegar (5% acidity) effectively dissolves mineral deposits, cleans glass, and deodorizes surfaces. It's not an EPA-registered disinfectant and does not reliably kill pathogens at normal concentrations. Use vinegar for cleaning (removing soil), not disinfection in food prep areas.
