A method for soaking hands in the context of a manual dishwashing operation, with reduced skin irritation resulting therefrom, which method comprises: 1) preparing an aqueous dishwashing solution from an effective amount for manual dishwashing of a liquid or gel dishwashing detergent composition comprising: (a) from about 5% to 99% by weight of detergent surfactant selected from the group consisting of polyhydroxy fatty acid amides; nonionic fatty alkylpolyglycosides; C8-22 alkyl sulfates; C8-22 alkyl either sulfates; C8-22 olefin sulfonates; C8-22 paraffin sulfates; C8-22 alkyl glyceryl ether sulfonates; fatty acid ester sulfonates; secondary alcohol sulfates; C11-16 secondary soaps; and mixtures of said surfactants; (b) from about 0.001% to 5% by weight of active protease in an amount sufficient to provide reduced skin irritation during manual dishwashing operations; and (c) from 0% to about 15% by weight of a detergency builder; (d) from about 1% to about 20% of a suds booster selected from the group consisting of ethylene oxide condensates, fatty acid amides, amino oxide, semipolar nonionics, betaines, sultaines, cationic surfactants, and mixtures thereof; said composition having a pH from about 4 to about 11; and thereafter 2) immersing the hands of the dishwasher in said dishwashing solution for a period of time which is effective to complete hand washing operations.
