Abstract

A dissolvable unit dose toilet cleaning composition for use with a wand. The unit dose contains surfactant, an organic acid, an organic acid buffering agent, and a dye system including a desiccant, a water-soluble dye, and optionally a colorant. The composition is compressed into a tablet or puck wherein at least 30% dissolves in 10 minutes when submerged in toilet water. Upon exposing a surface of the unit dose composition to water in the toilet, the water-soluble dye colors the water in the toilet. Pressing the wetted surface of the unit dose composition to a surface of the toilet, the water-soluble dye colors the surface of the toilet.
