The Final Verdict

Both options land in a similar higher-concern band. If you are trying to build a very low-tox setup, consider phasing both out over time in favor of more inert swaps.

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

Dawn Original Dish Soap

⚠️ USE WITH CAUTION

Cutting grease on dishes

Materials

Synthetic surfactants (sodium lauryl sulfate)
artificial fragrance
dyes

Common claims

Cuts grease fast
Used by wildlife rescuers

Concerns / watch-outs

Contains synthetic fragrance (undisclosed parfum chemicals)
Contains artificial dyes
Formaldehyde-releasing preservatives in some variants

Notes

The dominant market dish soap, but contains undisclosed fragrance chemicals and artificial dyes. Effective, but not a top pick for low-tox households.
