Abstract
Warewashing detergents suitable for dishwashing, immersion or dipping cleaning, and hard surface cleaning are disclosed for use on hard surfaces, including for example alkaline sensitive metals, such as aluminum or aluminum containing alloys. Alkaline compositions of a mixture of phosphono ethane carboxylates phosphono oligomers and methods employing the same are disclosed. The compositions eliminate the use of highly abrasive silicates, while retaining cleaning performance and corrosion prevention. The compositions according to the invention prevent the corrosive effect of highly alkaline compositions on aluminum or aluminum containing alloys.
