Designed for easy drop-in use, each 50g block lasts up to 240 flushes, releasing a powerful detergent that keeps your toilet bowl fresh, stain-free, and visually clean with a clear blue flush. Available in multiple refreshing scents and safe for septic tanks, it’s the ultimate low-effort upgrade for a pristine bathroom experience. ## Description Harpic Flushmatic toilet cleaning cistern block is a drop-in tank tablet which can be used for any accessible cistern. It works by creating strong foam every time you flush the toilet, which helps to maintain cleanliness in the toilet bowl. Harpic Flushmatic toilet cleaner works from inside the cistern to release a dose of powerful detergent with every flush. Distributing the liquid across the bowl, it helps you maintain a hygienic and fresh toilet and prevents the build-up of stains giving you a continuous clean toilet. You need not remove the pleated cloth wrapper on the block as this will dissolve in the water till it finishes, just drop the block directly into the cistern. For best results drop it at the opposite end to the water inlet, by the float. Wait for 10 minutes to let the block mix, before the first flush. Harpic Flushmatic toilet cistern block is a toilet hygiene product for continuous cleaning without any mess. It is touch free and hygienic and dissolves completely when finished. A single block lasts up to a month depending upon individual usage. Also, it lets you know when it needs replacing as the colour of the flushed water starts to fade. To keep the freshness going replace it with a new Flushmatic block as soon as the colour starts to fade. Harpic Flushmatic toilet cleaner is safe to be used with septic tanks and all other toilet cleaners. For regular cleaning, use Harpic liquid. With the new improved formula, now each block lasts upto 240 flushes. ## Features - In Cistern toilet cleaning block - Clear blue water on every flush - Maintains hygiene of toilet on every flush - Gives continuous cleaning and foaming - Each block lasts upto 240 flushes - Available in Marine, Citrus and Lavender variant and in various sizes: 50g, 100g, 150g ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08VF93S9V | | ASIN | B08VF93S9V | | Best Sellers Rank | #1,211 in Health & Personal Care ( See Top 100 in Health & Personal Care ) #4 in Toilet Blocks & Refills | | Brand Name | Harpic | | Contains Liquid Contents? | No | | Customer Reviews | 4.1 4.1 out of 5 stars (6,447) | | Date First Available | 29 January 2021 | | Generic Name | Toilet Block | | Included Components | Benzenesulfonic Acid, C10-13 Alkyl Derivs, Sodiul Salt, Alcohol, C12-14, Ethoxylated,Anionic Surfactants Parfum, Benzyl Benzoate, Coumarin and Limonene | | Included Components | Benzenesulfonic Acid, C10-13 Alkyl Derivs, Sodiul Salt, Alcohol, C12-14, Ethoxylated,Anionic Surfactants Parfum, Benzyl Benzoate, Coumarin and Limonene | | Item Dimensions LxWxH | 16.1 x 2.1 x 4.1 Centimeters | | Item Form | Tablet | | Item Type Name | Toilet Block | | Item Volume | 0.3 Kilograms | | Item Weight | 50 Grams | | Item Weight | 50 g | | Item model number | 3163939 | | Manufacturer | 6/10, Nalkura Central Road, P.O. - Badu, Distt - 24pgs(N), West Bengal, Pin - 700128|1800 102 7245 ;Consumercare_In@reckitt.com, Reckitt benckiser | | Manufacturer | 6/10, Nalkura Central Road, P.O. - Badu, Distt - 24pgs(N), West Bengal, Pin - 700128|1800 102 7245 ;Consumercare_In@reckitt.com, Reckitt benckiser | | Manufacturer Contact Information | 6/10, Nalkura Central Road, P.O. - Badu, Distt - 24pgs(N), West Bengal, Pin - 700128|1800 102 7245 ;Consumercare_In@reckitt.com | | Material Features | easy to use and cleans with every flush | | Model Number | 3163939 | | Net Quantity | 6 Count | | Number of Items | 6 | | Packer | Chemisol India Pvt.
