CLEANING COMPOSITIONS AND METHODS FOR BURNT-ON FOOD AND OIL RESIDUES
Disclosed herein are compositions comprising a solubilizing agent for the removal of burnt-on, cooked-on, baked-on, dried-on and charred organic food and oil residues from surfaces comprising alcohol, a coupling agent, water, an anti-deposition agent, a pH buffer and a surfactant system that preferably includes a fermentation supernatant, where the supernatant contains essentially stress proteins. Further enclosed are methods of cleaning for ovens, industrial cooking equipment and the like.
