Abstract

A cleaning agent for hard surfaces and methods for cleaning are provided herein. In one embodiment, the cleaning agent includes at least one first amylase, wherein the first amylase is an α-amylase from Bacillus sp. No. 707 or a functional fragment or a variant thereof. The cleaning agent further includes at least one second amylase, wherein the second amylase is an AA560 α-amylase from Bacillus sp. or a functional fragment or a variant thereof. In another embodiment, the method includes dispensing the cleaning agent into the interior of an automatic dishwasher while a dishwashing program is being executed, before the main washing cycle begins, or in the course of the main washing cycle.
