Abstract: Formulations for dissolvable solid unit dose toilet cleaning compositions containing an anionic surfactant, a carbonate or bicarbonate salt, a water-soluble filler and an organic acid, wherein the ratio of anionic surfactant to filler is 1:6 to 5:1. The filler includes clay, a sugar or a salt. The solid unit dose can be a tablet or compressed solid that engages with a wand to clean a toilet. The solids dissolve and can be flushed after use.

Abstract: A cleaning system includes a handling tool for a dissolvable cleaner block. The handling tool includes a wand and a retainer arrangement attached to the wand and moveable between a retaining position and a releasing position. The retainer arrangement is configured for removably attaching the wand to the dissolvable cleaner block when in the retaining position. The retainer arrangement is configured for releasing the dissolvable cleaner block when in the releasing position. The retainer arrangement includes at least one selectively moveable engagement member that removably engages the dissolvable cleaner block in the retaining position.
