Abstract:
Bioactive coatings that are stabilized against inactivation by weathering are provided including a base including an enzyme associated therein, and a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.
