Abstract
Liquid light duty cleaning compositions comprise an organic base (such as amines), a zinc salt (such as zinc halides or zinc citrate), and a complexing agent (such as EDTA). The compositions are useful in cleaning both at full strength and when diluted and do not cause staining of treated aluminum utensils.
