Abstract
A warewashing detergent composition is provided for use for in cleaning of alkaline sensitive metals such as aluminum or aluminum containing alloys. The compositions include alternatives to sodium tripolyphosphate and/or other phosphorous containing raw materials, while retaining cleaning performance and corrosion prevention. According to the invention, high molecular weight polyacrylates (polyacrylic acid homopolymers) with a molecular weight of at least about 5000 are used as corrosion inhibitors and can be included for aluminum protection in a number of different detergent compositions.
