A stable, high foaming, light duty liquid abrasive-containing dishwashing composition containing about 3% to 15% by weight of a water insoluble, particulate, low density abrasive suspended in an aqueous vehicle comprising at least one water-soluble, anionic sulfated or sulfonated detergent salt containing an alkyl group or alkenyl group having from 8 to 20 carbon atoms in the molecule, a betaine foam booster, about 1-3% by weight of a substantially completely hydrated colloidal clay as a stabilizing agent and, optionally, about 2% to 9% of a C.sub.2 -C.sub.3 alcohol is disclosed. The presence of the abrasive greatly improves the cleaning efficacy in removing baked-on and/or dried-on food residues without significant scratching when used full strength. Also, within the scope of the invention is a method of making liquid, abrasive-containing, dishwashing compositions which have improved stability against separation and are of low viscosity which comprises the steps of preparing a presheared clay/water mixture to substantially fully hydrate the clay suspending agent and adding said mixture to the remainder of the composition as the last ingredient with agitation sufficient to disperse the clay suspension without aeration of the resultant mixture and continuing such agitation while monitoring viscosity until a consistent minimum viscosity is attained after an initial increase to a viscosity maximum.
