A can of Comet

Comet is a powdered cleaning product and brand of related cleansing products. The brand was introduced in 1956 by Procter & Gamble, and was sold to Prestige Brands in 2001. Comet is now sold in North America and distributed in the United States by Prestige Brands. Procter & Gamble retained the rights to market the brand in Europe, and to the professional (non-home consumer) market in the USA.

According to the Material Safety Datasheets published by Procter and Gamble (P&G) (PGP Comet Deoderizing Cleanser with Chlorinol [1]) and Prestige Brands (Comet Powdered Cleanser), Comet contains 60-100% calcium carbonate. Other ingredients common to all Prestige Brands Comet Powdered Cleansers are listed as:[2]

The P&G Professional Comet MSDS details percentages :

  • Calcium Carbonate 60-100%
  • Sodium Carbonate 7-13%
  • Calcium Hydroxide 1-5%
  • Sodium Dichloro-s Triazinetrione Dihydrate 1-5%

Not all ingredients are listed on an MSDS.

Mixing cleaners containing bleach or other oxygenates such as Comet with cleaners or other products that contain ammonia or acid is dangerous. The P&G Comet MSDS states "Avoid contact with acids and ammonia."

Despite being labeled as scratch free, its label also advises the use of plenty of water on delicate surfaces. Comet is not recommended for use on silver, painted surfaces, walls, soft plastic, aluminum and rubber.

Popular culture[edit]

In the 1960s and 1970s, Comet was known for a series of popular television ads featuring the character of "Josephine the Plumber" (portrayed by actress Jane Withers). Later, in the 1980s, she gained a niece named JoAnn or Jo, who, after helping her customers with their plumbing issues, would show them a picture of her beloved Aunt Josephine, who uttered, via voiceover, "Nothing can hold a can to Comet!".


Comet, it makes your teeth turn green
Comet, it tastes like gasoline
Comet, it makes you vomit,
So get some Comet, and vomit today!
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
