Abstract
A cleaning device for cleaning a medical instrument such as an endoscope, which includes a fabric, wipe, or sponge impregnated with a composition which comprises: an enzyme such as a protease, alcalase, cellulase, lipolase: a surfactant and a humectant present in an amount to ensure that sufficient water is absorbed to reduce any hazard which would arise from use of the enzyme in dry form while maintain activity of the enzyme during storage. The cleaning device is adapted to remove at least a portion of externally adherent soiling on a surgical instrument by mechanical wiping; and to redistribute any remaining external soiling such that it is distributed as a film of thinner and more uniform thickness than on the unwiped instrument. The invention also relates to packaging of the cleaning device, and methods of use thereof.
