When examined under a microscope, most household surfaces are actually porous—even so-called "hard" surfaces—which means they can harbor dirt and grime that's invisible to the naked eye. Probiotics are small enough to reach deep into the crevices of household surfaces. Our products use spore technology (or what we call, “micro-helpers”), to help chew up and break down dirt by producing powerful enzymes. Think of them as microscopic enzyme factories and you'll get the idea.
Enzymes are like selective scissors that snip soils into easy-to-clean pieces. Our Probiotic micro-helpers know and make just which enzyme is needed to break down the soils in your home, from grease to grime to mold and mildew stains.
And once they get going, probiotic micro-helpers provide up to 7-day cleaning power in deep nooks and crannies, even after you've wiped the surface and thrown in the towel.

Unlike other products that only contain postbiotic ferments and extracts—which are produced by probiotics once they get to work—Mrs. Meyer’s Clean Day Probiotic Cleaners include active probiotic bacillus spores. That means you're getting a hardworking, microscopic deep clean with every use.
And like all our products, our Probiotic Cleaners are made with plant-based ingredients, as well as other thoughtfully chosen ingredients. Our products are USDA Biobased and Leaping Bunny certified—not to mention they’re available in our beloved Lavender and Lemon Verbena scents.

Our probiotic micro-helpers break down and live off lots of different soils including fats, oils, starches, proteins, and fatty acids—components found in the soils and grime we have around our homes.
From garbage disposal build-up to soap scum to everyday grime, Mrs. Meyer’s Clean Day Probiotic Cleaners can clean a range of tough household messes.

Mrs. Meyer’s Clean Day Probiotic Cleaners are perfect for countertops, finished wood and tile floors, walls, porcelain, sinks and faucet, sealed stone and granite. Note that we don’t recommend using our products on sealed marble, as the cleaner may remove the sealant.
Always test a small amount on an inconspicuous area of your surface first.
Our Probiotic Drain Maintenance cleaner is safe for use in drains, pipes, and garbage disposals and is safe for septic systems.

Our homes—just like our bodies and the gardens in our backyards—contain a unique microbiome comprised of trillions of different micro-organisms working in harmony to keep things working. Some cleaning products, like disinfectants, tend to wipe out everything, including the good bacteria.
We take a thoughtful approach to cleaning, which is why Mrs. Meyer’s Clean Day Probiotic Cleaners don't kill bacteria or contain an antibacterial formula. The bacillus spores in our Probiotic Cleaners are friends, not foes. Allowing the “good” bacteria to work is what delivers the microscopic deep clean our products were made for.

The pH of Mrs. Meyer’s Clean Day Probiotic Cleaners varies and is specifically selected to provide the best clean for usage occasion.
Our Probiotic Daily Shower Spray and Probiotic Drain Maintenance are both pH 7. Our Probiotic Multi-Surface Cleaner and Probiotic Multi-Surface Concentrate are both pH 6, which is slightly lower than neutral but still gentle enough to be used on a variety of surfaces such as finished wood and tile floors, countertops, walls, porcelain, sinks and faucet, sealed stone and granite.

We have done extensive safety and human and environmental toxicology assessments for every one of Mrs. Meyer's Probiotic products. Talk with a doctor before using if you or a household member are immunocompromised.
