Cleaning composition containing a polysaccharide graft polymer compositon and methods of improving drainage

A method of cleaning a substrate with a detergent composition, the method comprising:

• mixing water with the detergent composition to form a use solution;
• and
• contacting the substrate with the use solution, wherein the use solution comprises:
• at least one alkali metal hydroxide present in an amount from about 150 ppm to about 1500 ppm;
• a surfactant comprising an ethylene oxide/propylene oxide block polymer;
• and
• a polysaccharide graft polymer composition present in an amount from about 5 ppm to about 500 ppm, the polysaccharide graft polymer composition comprising from about 5% to about 90% by weight polysaccharide residue and from about 10% to about 75% by weight residue of at least one ethylenically unsaturated monomer, and
• wherein the use solution has a pH in the range from about 10.5 to about 12.5.

A method for improving rinse water drainage from ware being washed, the method comprising:

• contacting the ware with a use solution that includes:
• sufficient alkali metal hydroxide to provide the use solution with a pH that is in the range of about 10.5 to about 12.5;
• a surfactant comprising an ethylene oxide/propylene oxide polymer;
• and
• about 5 to about 500 ppm of a polysaccharide graft polymer composition comprising:
• polysaccharide residue in an amount from about 5% to about 90% by weight of the polysaccharide graft polymer composition;
• and
• residue of at least one ethylenically unsaturated monomer present in an amount from about 10% to about 75% by weight of the polysaccharide graft polymer composition.
