Clorox Automatic Toilet Bowl Cleaner Tablets with Bleach provide continuous cleaning and sanitizing power for your toilet. Each pack contains 6 tablets of 3.5 oz each that clean and deodorize with the power of bleach, killing 99.9% of household bacteria in the toilet bowl water. Each tablet sanitizes the toilet bowl water in 5 minutes and cleans for up to 3 months, helping prevent tough hard water, mineral, and lime scale stains.

The tablets keep your toilet smelling fresh and sparkling clean with every flush, leaving bowl water crystal clear. Easy to use - simply drop a tablet in the toilet tank near the side wall away from the water valve opening, and let it do its work. The tablet does not harm septic tanks and is effective for up to 10 flushes per day in toilets that are flushed daily.
