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

Windex Ammonia-Free Glass Cleaner

⚠️ USE WITH CAUTION

Streak-free cleaning of glass, windows, and mirrors

Materials

Isopropyl alcohol
Water
Surfactants
Fragrance

Common claims

Streak-free shine
No ammonia
Safe for tinted glass

Concerns / watch-outs

Still contains synthetic fragrance and surfactant blend
Isopropyl alcohol fumes in enclosed spaces; ventilate when cleaning inside

Notes

A cleaner choice than ammonia-based Windex, but vinegar and water in a spray bottle does the same job without the fragrance and surfactant load.
