Well al coholic......
During my scientific experiment involving getting all the chicken fat off the roasting dish, I observed the interesting phenominana... that the oily goop wouldn't rinse off with plain potable H2O (otherwise referred to as tap water to the layman (common hardworking person {of either sex}[this being a reference to one of a breeding capable pair]), however the additionof a suitable surficant (dish washing liquid {the type equivalent that Madge soaks her fingers in}(is she deceased these days?) the oily substance suddenly assimilated with the water.
Experience lad.
