Abstract

A toilet cleaner composition containing perfume, at least one non-ionic surfactant, at least one alkylbenzene sulfonate, and at least one olefin sulfonate, is sufficiently malleable that it may be shaped into rotationally symmetrical toilet cleaner blocks, and in particular into spherical blocks, using a rolling machine or a press. The resulting rotationally-symmetrical toilet cleaner block may be part of a toilet cleaning system comprising at least one toilet cleaner block and at least one dispenser device for use in a toilet.
