used it in the early 1980s
I lived in a garden apartment complex during postgraduate training years (early to mid 1980s). There was a nicely appointed laundry room fairly close to my apt, but I had to descend a flight of stairs and walk perhaps 100 feet to reach it.
Fresh Start came in a clear plastic bottle with measuring cup cap, one of the first powders to have a built in measuring cup. Also, it was concentrated, so one capful was enough for a large load (vs. nearly a cup of Tide or other powder). Fresh Start was easy to transport to the laundry room, with a built-in handle, far easier than lugging a large box of Tide AND a measuring cup. Clothes came out clean, but as Whircool mentioned, they weren't particularly soiled in those days.
When I moved into my current home, I now had my own laundry area with plenty of room for storage, so I tended to use regular strength powders like Arm & Hammer. I moved over to liquids when Kirkland came out with the large rectangular dispensers of liquid detergent (the kind with the spigot).
And now that I have a front loader, I use HE detergents. My favorite is Persil MegaPerls, when I am able to bring it back from Germany. Second favorite is Tide HE powder. Failing those two, I fall back on Kirkland powder or liquid in a pinch (both say "HE" on the package but I am not really sure they are reformulated for HE washers).
