Mrs. Meyer’s Probiotic Drain Maintenance is a fresh way to prevent buildups in drains and pipes all over your home, and leave them with the floral, herbal, garden-inspired scent of Lavender or the refreshing, mild citrus scent of Lemon Verbena. Your new partners in hardworking home cleaning are probiotic micro-helpers that provide added ‘oomph’ to help prevent buildups in drains and pipes, and continue to break down grime. In nature, probiotic micro-helpers live within soil, where they survive off compounds such as fats, starches, proteins and fatty acids – similar to the things that make up the grime and soil that can be found in or on surfaces all around your home. Once applied, as instructed, to a surface in your home, these hungry micro-helpers self activate and start producing enzymes that chew up everyday soil and prevent buildups of grime. It takes time to see the results of their tireless work, but you can rest assured that they’ll still be there for days after you’re done, working hard to proactively keep your home clean. To use this drain cleaning solution, simply pour the required amount of probiotic drain cleaner into the drain, leave for the instructed time and, if required, follow with water. This bleach free cleaner does not unblock existing clogs but provides great proactive, preventative maintenance for septic systems, pipes, kitchen and bathroom sink drains, and garbage disposal units. This hardworking cleaner can be used in place of your normal drain cleaner as part of your regular cleaning routine, to help prevent buildups, and to keep your home feeling clean and filled with delightful garden scents. For best results, use this product every two to four weeks, as directed. Our probiotic cleaners contain natural cleaning power and are made with essential oils and other thoughtfully chosen ingredients. Mrs. Meyer’s Probiotic Drain Maintenance Lavender is a USDA Certified Biobased Product (88%) and comes in a bottle made with at least 30% post-production plastic.

Honest care, inspired by a Midwest garden

Mrs. Meyer’s began with a mom from Iowa who wanted cleaning products that worked as hard as she did — but smelled like her backyard, not a chemical lab. Drawing on the scents of real herbs and flowers, the brand crafts practical formulas with essential oils and other mindful ingredients. Every bottle reflects Midwest sensibility and a love for the natural world.
