There was a first step with liquid detergent, too.
Before it came in squeezy bottles, it came in metal can-type bottles. These looked something like taller versions of metal brake fluid cans, with a plastic screw top. They were lithographed with the branding and label instructions.
The brand I remember (this would have been 1957 or so) was Trend. It was a revolution; I was four or five at the time, and I was aware that this product was very desirable. The reaction of the housewives in my family was basically, "Holy ****!" - except that ladies didn't actually use that expression then.
After years of Ivory Flakes for dishwashing, a detergent that kept sudsing and actually cut grease without near-boiling water temps being necessary was some punkins.
And there was not one of us kids who didn't get in trouble for pouring a bunch of it into the sink and watching all the suds build up - as high as the sink, then over the edge, then onto the floor....
Draw the veil.
