Those old television commercials always had the best taglines. I think my all-time favorite is from a black-and-white cartoon commercial for Tide circa 1955:
Nothing else will wash as clean as Tide,
yet is so mild.
Nothing else will wash as clean as Tide . . .
The words roll off the tongue with a spring-like freshness. Then to address her secondary concern – she refuses to sacrifice delicacy for cleaning power – the tagline gently counters:
. . . yet is so mild.
The phrase has an Eastern rhythm. She really feels the word mild. And she feels reassured.
