Claims18
A method of washing dishes wherein said dishes are treated with an effective mount of a detergent composition comprising:
- A. a metallo catalyst selected from
- a) metallo porphin and water-soluble or water dispersable derivatives thereof;
- b) metallo porphyrin and water-soluble or water-dispersable derivatives thereof
- c) metallo phthalocyanine and water-soluble or water-dispersable derivatives thereof;
- B. an enzymatic system capable of generating hydrogen peroxide;
- and wherein further said metallo catalyst is present at a level of from 10.sup.-8 molar to 10.sup.-3 molar and said enzymatic system is present at a level to provide in the dishwashing method a constant generation of 0.005 to 10 ppm AvO per minute.
