Having a toilet cleaner that reliably removes limescale is essential, as few substitutes work satisfactorily. Zep Acidic Toilet Bowl Cleaner handles this tough job with ease.
Zep Acidic Toilet Bowl Cleaner is specially formulated with hydrochloric acid in a gel base that stays on the bowl’s surface for longer to fully disintegrate stubborn limescale.
Apply a generous layer of Zep around the toilet rim and let it flow down and coat the bowl. Leave it for at least 5 minutes, then scrub with a toilet brush. Repeat if necessary.
