Harpic is the brand name of a toilet cleaner launched in the United Kingdom in 1932 by Reckitt. It is currently available in Africa, the Middle East, South Asia, Asia Pacific, Europe, and the Americas. 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 Harry Pickup (hence the origin of the name Harpic), who was based in Roscoe Street, Scarborough, in North Yorkshire. He also invented Oxypic, which was a sealant used in cast iron heating systems, and patented the Lock & Lift circular manhole covers, which were used initially by the British Military. The company also produced the steel components used on the Mulberry harbours, for the D-day landings.
