Liquid stable enzyme compositions and methods of employing the same for cleaning, including warewashing and dishwashing, are disclosed. The stable enzyme compositions preferably employ an amphoteric surfactant stabilizing agent, such as disodium camphodiacetate (CADA), to stabilize a mixture of traditionally unstable enzymes, such as proteases and lipases.
