Harpic
Product brand
UnclaimedAn international household-cleaning brand best known for toilet cleaners and toilet-hygiene products.
Last updated August 31, 2026
Overview
Harpic is a household-cleaning brand best known for toilet-cleaning and toilet-hygiene products. The brand originated in the United Kingdom, where its original toilet cleaner was launched in 1932 by Reckitt and Sons, the predecessor of today’s Reckitt group. Its name is derived from Harry Pickup, the inventor associated with the original product. Pickup was based in Scarborough, North Yorkshire, and was also connected with other engineering inventions, including Oxypic, a sealant for cast-iron heating systems, and the Lock & Lift circular manhole cover. The wider company’s engineering work also included steel components used in the Mulberry harbours during the Normandy landings, although those activities were distinct from Harpic’s consumer-cleaning business. The brand’s central proposition is specialist cleaning and hygiene for toilets and bathrooms. Its products have historically used acidic cleaning chemistry, including hydrochloric acid in some formulations, to address mineral deposits, stains and other forms of toilet-bowl soil. Formulations vary by market and product, and packaging and regulatory requirements differ across jurisdictions. Harpic products have included liquid toilet cleaners, limescale removers, toilet-rim blocks, in-cistern systems, cleaning tablets, wipes and toilet-brush systems. Product names and availability are not uniform internationally; examples documented in the range include Harpic Power Plus, Harpic Max Rim Block, Harpic Hygienic, Harpic All in 1, Harpic Active Fresh Toilet Cleaner, Harpic 100% Limescale Remover Toilet Cleaner, Harpic Flushmatic and Harpic 10X Max Clean. Harpic has been marketed across Africa, the Middle East, South Asia, the Asia-Pacific region, Europe and the Americas. India is one of the brand’s important markets, but the brand’s historical origin is British rather than Indian. Its international presence reflects Reckitt’s model of adapting consumer-health and household-care brands to regional retail channels, local cleaning habits and market-specific product formats. Advertising has traditionally emphasized expert cleaning performance and coverage of the toilet bowl. In the United Kingdom, the long-running slogan “Cleans Round The Bend” linked the brand to the distinctive curved shape of a toilet bowl and became a recognizable part of its advertising identity. A later campaign, “Send for the Experts,” featured Tom Reynolds in a 2008 Harpic advertisement. The brand’s communication has generally focused on visible cleanliness, hygiene, stain removal, freshness and confidence in bathroom maintenance rather than on a single standardized product formula. Harpic remains an active Reckitt brand. Its portfolio extends beyond conventional liquid toilet cleaner into systems intended to maintain freshness between cleans, including rim blocks and in-cistern products. Because Reckitt sells the brand through multiple national organizations, the precise range, formulation, claims and packaging can differ by country. Publicly available reference material supports its identity as a global toilet-care brand, but does not establish a separate headquarters, a standalone stock listing or a complete current executive roster for Harpic itself.
History
Harpic began in the United Kingdom in 1932 as a toilet-cleaning product made by Reckitt and Sons. The product’s name is associated with Harry Pickup, an inventor based in Scarborough, North Yorkshire. Pickup’s work was not limited to consumer cleaning: he was also credited with Oxypic, a sealant used in cast-iron heating systems, and with the patented Lock & Lift circular manhole cover, which was initially used by the British Military. The company connected with this engineering work also produced steel components for the Mulberry harbours used during the Normandy landings. These engineering activities provide historical context for the brand’s origin but are separate from Harpic’s later role as a household-care product. From its early years, Harpic was promoted as a purpose-built toilet cleaner rather than a general-purpose detergent. United Kingdom advertising from the 1930s onward used the slogan “Cleans Round The Bend,” a reference to the curved interior of a toilet bowl and the product’s intended cleaning coverage. The phrase became strongly associated with the brand in British popular culture and was sometimes used informally to describe eccentricity. Harpic’s communication gradually developed around specialist expertise, hygiene, freshness and visible cleaning results. As Reckitt and Sons evolved into the modern Reckitt group, Harpic became part of a broader international portfolio of household and consumer brands. Distribution expanded beyond the United Kingdom into Africa, the Middle East, South Asia, the Asia-Pacific region, Europe and the Americas. Local markets have carried different product names, formats and claims. In India and other South Asian markets, the brand has become particularly prominent in toilet-care categories, while other markets have emphasized bathroom cleaning, limescale control or continuous freshness. The product architecture has broadened substantially from the original liquid toilet cleaner. Documented formats include toilet-cleaning liquids, bathroom cleaners, toilet-rim blocks, in-cistern products, tablets, wipes and brush systems. Product examples include Power Plus, Max Rim Block, Hygienic, All in 1, Active Fresh Toilet Cleaner, 100% Limescale Remover Toilet Cleaner, Flushmatic and 10X Max Clean. The exact formulation and portfolio vary by country. Reference material identifies hydrochloric acid as an active ingredient in a formulation containing 10% hydrochloric acid, together with other ingredients such as hydroxyethyl oleylamine, cetyltrimethylammonium bromide, ammonium chloride, methyl salicylate, butylated hydroxytoluene, colorants and deionized water. Such chemical details should not be assumed to apply to every Harpic product or market. Advertising remained an important part of Harpic’s brand development. In 2008, the “Send for the Experts” campaign featured Tom Reynolds and framed the product as a specialist solution for difficult toilet-cleaning work. The brand’s wider advertising history has consistently used expertise and performance as differentiators, while also communicating hygiene and freshness through product-specific claims. Harpic is currently an active Reckitt brand with an international market presence. It operates as a product brand rather than an independently listed company, and public reference material does not identify a separate Harpic headquarters or a standalone executive team. Its current identity is defined by specialist toilet and bathroom care, with a range that combines periodic deep cleaning with products designed to maintain freshness between cleans.
