toilet bowl bleach

Common scent options include fresh/rain-clean, pine, lemon, and unscented formulations.

Tablets are placed in the toilet tank and release cleaner with every flush to clean and deodorize the bowl. Individual tablets are stated to last up to 4 months; a four‑pack is described as lasting up to 16 months total.

Product descriptions indicate they remove and whiten mold and mildew stains, destroy mold and mildew buildup, and—when used as directed—can help prevent regrowth.

Many product details state disinfecting action, frequently noting they kill 99.9% of germs or of viruses and bacteria when used as directed; some listings also name specific pathogens such as the COVID-19 virus, norovirus, MRSA, Streptococcus, E. coli, Salmonella, and influenza.
