Bleach and Ammonia Combination for Heavy-Duty Bathroom Grime Blasting
Rex says

"Pouring both ammonia and bleach into a toilet bowl or mop bucket creates the ultimate heavy-duty deep-cleaning cocktail that cuts grease and bleaches stains simultaneously."
The science
-
Hypochlorite plus ammonia makes chloramine vapor
Sodium hypochlorite and ammonia react directly to form monochloramine and dichloramine, which leave solution as a gas. The reaction needs no heat and no effort - pouring the second product into a bowl already holding the first is enough. In a bathroom, the smallest and least ventilated room in the unit, the vapor concentrates at breathing height over the fixture you are leaning into.
-
The injury pattern is documented, not theoretical
Chloramine inhalation produces cough, chest tightness, shortness of breath and chemical pneumonitis. Pascuzzi and Storrow reported a mass-casualty event in Military Medicine from acute chloramine exposure, with multiple people needing care from a single release. That is the ceiling on this hack: not a bad smell, a documented multi-patient respiratory event.

There is no cleaning payoff to trade against it
The claim is that you get bleaching and degreasing at once. You do not. The two reagents consume each other producing chloramines and salt, so the hypochlorite is no longer available to oxidize stains and the ammonia is no longer available to cut grease. You spend both actives, gain nothing, and vent the product into your lungs.
Do it right
Pick one product and finish with it. Bleach the bowl, flush, rinse the bucket, open a window, and let the room air out before any ammonia or glass cleaner comes near it. For grout and grease, a single alkaline bathroom cleaner with a stiff brush does the work the "cocktail" is promising. Gloves, ventilation, one chemistry at a time.

Pascuzzi TA, Storrow AB - Military Medicine
"Peer-reviewed report of a mass-casualty incident caused by acute inhalation of chloramine gas, the product formed when hypochlorite bleach contacts ammonia. Establishes that chloramine release from mixed cleaning chemistry is a documented multi-patient respiratory emergency, not a theoretical hazard."
