My Mom used All for years, in fact it was nearly always on-hand unless I managed to get her to buy something else for a change, but for the few times she agreed, it was whatever I wanted that I could play with, and she still used her All. We had a water softener in Michigan and Colorado, so the low sudsing aspect of All was very appreciated. I know Mom always felt she couldn't use Tide without dealing with a sudsy rinse. Later when FreshStart came out, we loved that because it was easier to use (so compact) and as good if not even better at low sudsing. BUT, we are coupon clippers, so if we didn't find All on sale or have a coupon, I think Dash may have been the substitute that Mom liked. I can say that when I got my own Kenmore, I had a blast buying all the stuff that I wanted before and never could nag enough to get.
I rebuilt a 1979 model (built in 1980 or so) standard capacity Kenmore around 1992 or so. So it was about 12 years old. The machine had an odd, clay-like odor. Remember that gray clay we used in kindergarten, etc? Same smell.... Upon opening up the machine, I removed the basket and found a couple HANDFULLS of this thick, goey clayish "stuff" that clung to the centerpost, it clung also to the inner post of the basket, and was all the way up to the basket drive block. It was cold, moist, and moldable, and the spin action of the baskets wisked it up the post like stiff dough does in between the beaters in a Sunbeam mixer. I decided that this was residue from a cheap powder detergent....at least that's what I hoped as it was the least gross of the options I had.
