According to the Material Safety Data Sheets (MSDS) published by Procter & Gamble for "PGP Comet Deoderizing Cleanser with Chlorinol"[4] and Prestige Brands for "Comet Powdered Cleanser", Comet cleanser contains 60–100% calcium carbonate (CaCO3).

Ingredients that are common to all Prestige Brands Comet Powdered Cleansers are listed as:[5]

The P&G Professional Comet MSDS details percentages of the major component chemicals:

  • Calcium carbonate: 60-100%
  • Sodium carbonate: 7-13%
  • Calcium hydroxide: 1-5%
  • Sodium dichloro-s triazinetrione dihydrate: 1-5%

(Note: Not all ingredients are listed on an MSDS.)


Mixing cleaning products containing bleach or other oxygenates (such as Comet) with products that contain ammonia or acid is dangerous. The P&G Comet MSDS specifically warns to: "Avoid contact with acids and ammonia."

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


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

An alternative version uses different first lines:

Comet, it tastes like gasoline
Comet, it makes your insides clean


Comet, it makes your toilet clean
Comet, it makes your teeth turn green
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
