How Cleaning Products Affect the Air in Your Bay Area Home

Most people think about air quality when the sky turns orange. Fewer think about it when they're spraying down the kitchen counter. But for a lot of Bay Area homes, the second one happens a lot more often.

Why indoor air is worth paying attention to

The EPA estimates that people spend roughly 90 percent of their time indoors, and it notes that indoor concentrations of some pollutants can be two to five times higher than outdoors. Those pollutants come from a lot of places: gas stoves, new furniture, paint, candles. Cleaning products are on that list too.

The difference is that cleaning products are something you use on purpose, every week, in every room. Which also makes them one of the easiest things to change.

What's actually coming off the bottle

Many conventional cleaners and air fresheners release volatile organic compounds, usually shortened to VOCs. These are chemicals that evaporate at room temperature, which is why you can smell them. Some come from solvents. A lot come from fragrance.

"Fragrance" on a label can stand in for a long list of ingredients. California's Cleaning Product Right to Know Act, passed in 2017, now requires companies to disclose intentionally added ingredients online and on the label, including many fragrance allergens. That's a big step, but it still means reading the fine print.

Researchers have also linked frequent use of some cleaning sprays to breathing problems, especially among people who clean for a living. That's one reason we care about this as a company. Our cleaners are in these homes all day, every day.

Why the Bay Area makes this more noticeable

A few things about living here keep indoor air sitting still:

• Fog. In the Sunset, Richmond, and Daly City, a lot of people keep windows closed most of the summer because it's cold and damp out.
• Wildfire smoke. Smoke events and Spare the Air days have pushed everyone indoors with the windows sealed, sometimes for a week or more.
• Small, older homes. Plenty of Bay Area apartments and flats were built long before modern ventilation. Bathrooms without exhaust fans are common.
• Working from home. If your living room is also your office, you're breathing that air eight hours a day instead of two.

Put those together and the smell of a bleach-heavy bathroom clean can hang around a lot longer than it would in a big, drafty house.

Simple ways to keep your air cleaner while you clean

You don't need to overhaul your whole routine. A few changes go a long way:

• Skip air fresheners and scented plug-ins. A clean home doesn't need a cover scent. If you want something, open a window for ten minutes.
• Choose unscented or lightly scented products. A little essential oil is very different from heavy synthetic fragrance.
• Pour instead of spray when you can. Spraying puts fine droplets in the air you breathe. Spraying onto a cloth instead of the surface helps too.
• Use microfiber. It traps dust instead of pushing it around, so you need less product and less dusting overall.
• Vacuum with a good filter. A lot of what makes indoor air dusty is settled dust getting kicked back up.
• Never mix products. Bleach plus ammonia, or bleach plus acids like some toilet cleaners, can release toxic gases.

What we do on every clean

Every Sano clean uses eco-friendly products from Branch Basics, Koala Eco, and Seventh Generation. They're plant-based brands with clear ingredient lists, and they handle real kitchen grease and bathroom buildup without the harsh smell. We bring all the supplies, so nothing questionable has to live under your sink. We wrote a full breakdown of the products we use and why.

When the weather allows, we crack a window or run the bathroom fan while we work. When it doesn't, the products we choose matter even more.

The bottom line

You can't control wildfire season or the fog. You can control what you spray in your kitchen. For most Bay Area homes, switching to gentler cleaning products is one of the cheapest, easiest ways to keep indoor air a little healthier.

We clean homes across San Francisco, Oakland, Berkeley, Walnut Creek, and the rest of the Bay Area.
