In-Tank Toilet Cleaner Duo-Cubes

Metra 023400072712 is a set of four in-tank toilet cleaning cubes designed for households that want continuous bowl maintenance between deep cleans. Each cube releases cleaning agents with every flush to help keep the toilet fresh without turning the water blue.

Anti-Clogging Formula and Clear Water Design

The cubes are formulated with anti-clogging technology to help dissolve toilet paper residue over time while remaining safe for toilet components and septic systems. A water-soluble wrapper dissolves in the tank so no handling of loose product is required during installation.

Up to 16 Weeks of Continuous Cleaning

One cube lasts up to four weeks, giving the four-count pack a total of up to 16 weeks of automatic cleaning and freshening power. This duration suits buyers looking for a low-effort way to fight toilet ring, hard water and limescale stains between regular scrubbing.
