- In 1969, The Wacky Packages series included a mock ad, drafted by Art Spiegelman and painted by Tom Sutton, depicting a flag-waving American Revolutionary soldier and a pair of club-wielding policemen chasing a group of hippies carrying picket signs inscribed "For Freedom!" and "Love! Not War!", with a prominent slogan, "Keep America Clean with Commie Cleanser" and a can, depicting a caricature of Uncle Sam, and inscribed, "Extra Strong Commie Cleanser" and "Gets Rid of Reds, Pinkos, Hippies, Yippies & Flippies". The mock ad has also appeared depicting the can alone.
- A children's song about Comet is sung to the tune of the Colonel Bogey March. It rhymes "Comet" with "vomit." The complete lyrics are:
- Comet, it makes your teeth turn green
- Comet, it tastes like gasoline
- Comet, it makes you vomit,
- So get some Comet, and vomit today!
- The song "Rip Her to Shreds" by the American rock/new wave band Blondie mentions Comet:
- She got the nerve to tell me she's not on it
- But her expression is too serene
- Yeah, she looks like she washes with Comet
- Always looking to create a scene
