Jon, Actually in grandma's time when soap was used for cleaning, a rich layer of suds indicated that the soap solution was strong enough for cleaning and the suds assured that the solution was suspending the soil. When the suds broke down, the soap solution was finished for cleaning and whether it was fabrics or dishes, the soil and grease were no longer going to be removed and the grease came floating to the top.
We know that is not the same for detergents. My father would demonstrate this for kitchen workers by filling a sink with hot water then, after he had shut off the water, adding enough liquid hand dishwashing detergent for the proper concentration without creating a bubble. Then he would take a pot where grease has been been allowed to bake onto the outside because people had only washed the inside. He would immerse it in the water with one hand and in his other hand he held a green 3M scrubbing pad with which he would scrub the outside. He would not scrub the entire pan clean, just a portion of it. He would then lift it out of the sudsless water with a portion of the aluminum shining bright and rinse it off. People who were raised on using soap did not understand how modern detergents could clean without suds (I remember hearing gasps of "magic") and frankly, I don't know that they were convinced, but he did it in the presence of the manager so there would be no talk of how the detergent did not clean because the suds were not billowing out of the sink.
So please be careful to make the distinction between soap and detergents and old style detergents with foaming surfactants and non-foaming ones. Having a frontloader go into spin and sudslock with an HE detergent in a load of towels should be the acid test between regular detergents and Rosalie's. BTW, who is Rosalie?
