Professor Amos Toilet & Tank Cleaner

A cleaner bathroom, without the hard scrub

Professor Amos Toilet & Tank Cleaner has a thick formula that clings to the bowl while you brush, helping tackle hard-water buildup, limescale, rust, and everyday stains. Its green-to-blue color change makes it easy to see when the formula meets water. It’s a practical addition to the Essential Fraternity home routine: get the job done, then get on with your day.

Made in the USA, with up to 24 applications. Use it in toilet bowls and tanks following the product directions.

Important: Keep the cleaner away from stone, porous surfaces, and metal bathroom or kitchen fixtures, including faucets and showerheads.
