Stabilization and activation of protease for use at high temperature

A method of cleaning a hard surface comprising:

• (a) forming an organic activator-stabilizer;
• (b) contacting the hard surface with sufficient organic activator-stabilizer to form an aqueous use solution of from about 0.1 ppm to about 10,000 ppm organic activator-stabilizer;
• and
• (c) contacting the hard surface with sufficient enzyme to generate from about 0.1 ppm to about 10,000 ppm enzymes in said aqueous use solution, wherein said organic activator-stabilizer increases stabilization of said enzymes at temperatures in excess of at least 150° F. up to temperatures of 180° F.

An enzyme stabilizing and activating aqueous use solution for use at elevated temperatures comprising:

• (a) an aqueous use solution;
• (b) from about 0.1 ppm to about 10,000 ppm enzymes;
• and
• (c) from about 0.1 ppm to about 10,000 ppm organic activator-stabilizers selected from the group consisting of heat-deactivated enzymes, denatured enzymes, zwitterionic materials and combinations of the same, and wherein said organic activator-stabilizers increase stabilization of said enzymes at temperatures in excess of at least 150° F. up to temperatures of 180° F.
