## Overview

Harpic Flushmatic Marine 150 gm is a biodegradable, alcohol-free in-cistern toilet cleaner block that provides continuous foaming and cleaning for up to 240 flushes. Designed for hassle-free use, it releases a powerful detergent dose with every flush, maintaining hygiene and a fresh marine scent while being safe for septic tanks.

## 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.

Review: One packet opened - One packe is opened
Review: Rating it average - Not sure how long it was made to last, but one tablet lasts roughly one month in an infrequently used water closet. Or around 20 days in one used regularly. The fragrance is good, but I didnt notice any additional cleaning happening as described after one month use. It cleans no better than when regular water is used. If it disinfects bacteria and germs, thats beyond standard means to analyze. Overall its okay for the price but might not consider spending extra money on it in the future.
