The Final Verdict

Comet Powder Cleanser

⚠️ USE WITH CAUTION

Abrasive scrubbing of sinks, tubs, and bathroom tiles

Materials

Calcium carbonate abrasive
Sodium dichloroisocyanurate (chlorine source)
Fragrance

Common claims

Disinfects while it cleans
Whitening power
Tough on stains

Concerns / watch-outs

Contains chlorine-releasing compounds; generates chlorine gas fumes, especially in warm water
Fragrance in a powder format means inhalation exposure during application

Notes

More abrasive and harsher than Bon Ami. The chlorine component is effective but adds respiratory concerns. Bon Ami or baking soda handle most scrubbing tasks without the chlorine.

Cleaner alternatives

Mrs. Meyer's Clean Day Dish Soap

⚠️ USE WITH CAUTION

Hand dishwashing

Materials

Surfactants
synthetic fragrance (Basil, Lemon Verbena, etc.)

Common claims

Plant-derived ingredients
Biodegradable formula
Cruelty-free

Concerns / watch-outs

Contains synthetic fragrance — undisclosed parfum chemicals
Some variants include methylisothiazolinone (MI), a common sensitizer
Not fragrance-free; not ideal for sensitive skin

Notes

Better than most conventional dish soaps but still uses synthetic fragrance blends. A step up from Dawn but not a top pick for fragrance-sensitive households.
