Point taken, but since when isn't 'dish soap' a mystery mix of
chemicals?  Usually the stuff from the grocery is some undisclosed
mixture of synthetic detergents, semi-synthetic detergents, coloring,
perfume, and thickening agents.  No soap (soaponified fats) at all. 
Sometimes the stuff from the 'health food' stores is even scarier.
