> Anyone using a washer, listens for it I hate laundry. I still have no idea how to do it; I referred to detergent as laundry sauce a few years ago after forgetting the word. (Thank you, subconscious of mine.) The new machines with screens are a nuisance. Apparently to you, somebody competent. But also to those of us for whom listening to one’s washing machine sounds like advice from a laundry Lorax.
While I greatly appreciate the coinage "laundry sauce" I think the great majority of people know how to do this stuff and it's not hard to find out how.
I design complex medical implants, can build a car from scratch, and even understand some of the polymer chemistry of fabrics, but still struggle with laundry despite doing it for 20 years.
I have settled into the heuristic of warm wash & repeat until clean + dryers destroy anything but socks.
