Harpic Fresh Matic commercial from 1985.

Harpic is the brand name of a toilet bowl cleaner launched in England in the 1920s and now marketed by Reckitt Benckiser.

The brand is now available in Africa, the Middle East, Asia, Pacific, Europe, Latin America and Eastern Europe.

The toilet cleaning products marketed under the brand name include liquids, tablets, wipes, brush systems, toilet bowl and cistern blocks.

The original toilet cleaner was invented by Mr Harry Pickup, who was based in Roscoe Street, Scarborough, in North Yorkshire. He also invented Oxypic, which was a sealant used in cast iron heating systems.

Advertising
UK advertisements from the 1930s onwards used the slogan ‘Cleans Round The Bend’. (For this reason the name is occasionally used as slang for “crazy”: “clean round the bend”, where “clean” means “absolutely” and “round the bend” means “insane”.)
