No more scrubbing! ChemFree™ toilet bowl cleaner lasts 5 years.
Don't waste money on harsh chemical cleaners. Don't spend your time scrubbing.

Hidden in the flow-through cartridge are advanced hydro-mineral magnets and Bact-O-Bane antibacterial fiber. They work without adding anything to the water, or removing anything from it. Made in the USA. 4"x1-1/2"x1/2".
