Josephine from the Comet cleanser commercials was played by Jane Withers, who had already been famous years earlier as a 1930s child star. Later, a whole new generation knew her not from the movies, but as Josephine the Plumber.
Josephine appeared in Comet commercials from the 1960s into the 1970s, usually dressed in white work overalls and showing how Comet could handle stains, sinks, tubs, and other tough cleaning jobs.
What made the campaign stand out was that a woman plumber was highly unusual on TV at the time. That was part of the hook. Instead of using a typical male repairman, Comet gave viewers Josephine — friendly, confident, and no-nonsense. She knew the pipes, the porcelain, and exactly what cleaner to use.
The character worked because she felt practical and believable. She was not glamorous or fancy. She was the woman who knew how to get the job done. Jane Withers reportedly even took a plumbing course to make the role feel more authentic.
For a lot of viewers, Josephine was one of those commercial faces you trusted. If she said Comet cleaned better, you believed her. She had that perfect old-school ad quality: part neighbor, part expert, part TV personality, and completely unforgettable.
