A solid detergent composition for cleaning hard surfaces comprises an active detergent constituent which also serves as a carrier material, and a cleaning constituent. The cleaning constituent can comprise an acidic material, which is effective to remove soap scum from hard surfaces, or a bleach functional at a basic pH which is effective to bleach mildew. The detergent constituent comprises the essentially anhydrous neutralization product of an anionic surfactant such as a linear alkylbenzene sulfonic acid and a solid neutralizing material, such as a salt, oxide, or hydroxide of an alkali or alkaline earth metal, including sodium carbonate. The cleaning constituent, along with a filler material, is added to the detergent constituent during the course of and prior to the termination of the neutralization reaction. Also disclosed is a reusable scrubber pad incorporating the solid detergent composition. Within other aspects of the invention are solid, acidic cleaning compositions containing at least one polycarboxylic acid, solid cleaning compositions containing a bleach functional at a basic pH, and methods for manufacturing and using both the acid pH and the basic pH solid cleaning compositions.

A reusable cleaning pad which comprises: a scrubber layer of coarse, resiliant, porous material to scrub a soiled surface, said scrubber layer having a generally planar front surface for contacting the soiled surface and a rear surface; a backing material covering and affixed to the rear surface of said scrubber layer; and a solid detergent composition disposed intermediate said scrubber layer and said backing material, which composition comprises a mixture of (a) a carrier composition which comprises an anionic detergent sulfonate salt which is the reaction product of an essentially anhydrous neutralization reaction between an anionic C10-C22 alkyl aryl sulfonic acid and a solid neutralizing agent; and (b) an active cleaning constituent selected from the group consisting of organic polycarboxylic acids and alkaline pH functional bleaches, wherein said cleaning constituent is added to said reaction product during the course of but prior to the conclusion of the neutralization reaction which provides for the slow release of the active cleaning constituents and which permits multiple reuse.
