BD Toilet Cleaner Gel 500ml Septic Safe Deep Clean Deodorizer Removes Limescale Rust Brown Stain

The Ring Under the Rim. The Smell You Stopped Noticing. Both Gone.There is a specific kind of dirt that toilets develop. It is not ordinary grime. It is limescale from hard water. Rust from old pipes. Mineral deposits that harden into a brown ring just below the rim. It looks permanent. It smells permanent too.Ordinary cleaning does not remove it. You pour something in, scrub for a minute, flush. The ring stays. The smell comes back within a day.This toilet bowl cleaner was formulated for that exact problem.
