Detergents are man-made degreasing agents.
To put the normal label to it I am talking about Washing up liquid. Washing-up detergents can dry up the skin and cause vomiting and diarrhea if swallowed neat. Washing-up detergents also contain a drying agent, which may increase the body's absorption of the pesticide residues that are present in a great many foods. Alternative Washing soda crystals with a little soap dissolved in very hot water will get dishes clean with much less damage to the environment. In soft-water areas you will not need the soda crystals, and perhaps not even the soap, except for greasy items.
