Fluidmaster Flush N' Sparkle No Scent Continuous Toilet Cleaning System Refill 2 Liquid

Fluidmaster's Flush 'n Sparkle self-cleaning toilet system is designed to achieve safe and effective hands-free cleaning for any toilet. Toilet flappers tend to wear out more often if you use drop-in bleach tablets. Contrary to popular belief, drop-in bleach tables do not clean the toilet bowl. The bleach stays in the toilet tank the entire time, affecting the flapper and other toilet parts and is flushed out of the pipes when you flush the toilet. The bleach tablet does not get a chance to clean the bowl. Flush 'n Sparkle does not fill up the toilet tank with bleach as it is kept in a reservoir and hence does not destroy the toilet parts. The bleach from Flush 'n Sparkle goes directly into the overflow tube of the flush valve keeping the toilet bowl sparkling clean and the bowl water is safe.
