What a funny world we live in. I mean, do they rinse their clothes or bodies or hair after the soap has done its job?
I use the dishwasher some and hand wash some. I first get food etc.off then wash with soapy sponge, then rinse in hot running water. Til the plate (top and bottom always) squeaks! That’s how my grandmother taught me. The squeak meant the soap was gone:;)
Same as my grams...job wasn't finished until they squeaked.
I remember a dish detergent commercial, which, at the end, the lady would rub her thumb across the plate to show how squeaky clean the dishes were.
