Harpic Flushmatic in-cistern toilet cleaner

Harpic is a global brand of toilet cleaner that originated in the United Kingdom around 1920. Originally created by Harry Pickup, the brand name was a contraction of his own name. Harpic is specifically designed to tackle toilet hygiene and scale removal, and its product range has since expanded to include in-cistern blocks and rim-fleshes, as seen with this 'Flushmatic' product which highlights a reduction in plastic waste.

Today, Harpic is part of the extensive portfolio of Reckitt (formerly Reckitt Benckiser), a British multinational consumer goods company. While the brand has British roots, its products are manufactured in several regions to serve global markets, with significant production facilities located in India, the Middle East, and Europe. In Australia, the brand is managed by the local subsidiary Reckitt Benckiser (Australia) Pty Limited and is a staple in the household cleaning category across major supermarkets.
