A method of dispensing a solid controlled release composition comprising:
- contacting the solid composition with a water source to generate a use solution of the composition, wherein the solid composition comprises a hydroxide alkalinity source, at least one polysaccharide material having between about a 1 wt % to about 2 wt-% aqueous solution viscosity at 25° C. of between about 250 cps and about 5000 cps, and wherein the at least one polysaccharide material comprises carboxymethylcellulose (CMC) and a surfactant;
- and
- contacting wares with the use solution at pH from about 10 to about 13 for a sufficient amount of time to remove and/or solubilize soils, wherein the solid composition lasts at least 10 cycles.
