Clessentials In-Cistern Toilet Blocks provide continuous automated bowl maintenance with zero effort. Placed directly into the toilet cistern, each block gradually releases concentrated cleaning agents, water softeners, and blue foaming surfactants with every flush. The slow-dissolve formula actively prevents mineral and limescale adhesion, breaks down organic soil, and dyes the water a crisp, clean blue—keeping your toilet fresh and sanitary between deep cleans.

Keeps the toilet clean between deep scrubs
Review: Drop one in the tank and forget about it. It turns the water a nice clear blue, creates good foam on every flush, and keeps water ring marks from forming. One block lasted me nearly three weeks in a busy household toilet.
