## Overview

Harpic Flushmatic In-Cistern Toilet Cleaner Blocks deliver up to 240 flushes of continuous cleaning and foaming action. Designed for easy drop-in use, these blocks maintain toilet hygiene by releasing a powerful detergent with every flush, leaving clear blue water and preventing stains.

## 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.
