Use our best-selling non-toxic Chemfree Toilet Bowl Cleaner to keep your toilet clean for 5 years or 50,000 flushes. (Safe for Septic systems!)

Hydro-electric power plants use the physics principles incorporated in the non-toxic ChemFree Toilet Bowl Cleaner to keep water intakes clean for years. Made in the U.S.A., eco-friendly and non-toxic, Chemfree's hydro-mineral magnets prevent toiletbowl stains by keeping minerals in the water from forming bonds that cause the stains in the bowl and the lime buildup that occurs on the tank parts.

Just drop it in the tank.

As an added bonus, the ChemFree housing contains Bact-O-Bane, a non-toxic fiber embedded into the housing that kills bacteria on contact by disrupting the metabolic function of thin-walled micro-organisms like mold and fungus, killing them instantly. This is backed up with a 5-year 50,000 flush study that shows no deterioration in performance. Get one for each toilet today.

(Of course, you do need to start with a clean toilet. And it may require two for extra hard water, but it will still save you a ton of money, and they still work great. In some cases, if you have a water softener for the toilet water, it may not work as well.) ChemFree MSDS below.
