Humble Suds is a small cleaning brand run by two moms — Holli Schuab and Jennifer Parnell — in Evergreen, Colorado. All of their products are made from powerful, plant-based ingredients and packaged with recyclable materials. They recommend applying a tablespoon of their scouring paste to a cloth and then scrubbing in a circular motion.
Promising review: “I used the surface scrub today on my bathtub and bathroom sink, and it works WONDERS! I love that the ingredients are minimal and organic, but gets the job done. I love this product!” —hinako jefferson
