How to Use This Scrub

You can use this versatile scrub on various surfaces such as tubs, sinks (both bathroom and kitchen), and even toilets. Simply use 1 tablespoon at a time for cleaning. To clean toilet bowls, add 1 tablespoon, scrub with a toilet brush, and let it sit for 5 minutes before flushing. For sinks, add 1 tablespoon, gently scrub with a brush, cloth, or toothbrush, let it sit for 2 minutes, and rinse. Similarly, for bathtubs, add 1 tablespoon to the shower/tub floor, gently scrub with a brush, toothbrush, or cloth, let it sit for 2-5 minutes, and rinse.

It’s a convenient and effective solution for multiple cleaning needs. Don’t use this scrub on natural stones like real marble and granite as well as grout. Be gentle when scrubbing no matter what.
