Cleaning best practice
The short answer
Bleach with ammonia produces chloramine gas and bleach with acid produces chlorine gas; both are hazardous in a small bathroom.
Most domestic poisonings connected with cleaning come from combining products, not from using one of them. Two of these combinations are common enough to name explicitly.
How it is done
- Never combine chlorine bleach with any ammonia-based cleaner, including many glass sprays.
- Never combine bleach with acidic descalers or limescale removers.
- Rinse a surface thoroughly before switching product families.
- Ventilate: open a window or run extraction whenever either family is in use.
Why it matters
A bathroom is small, warm and often unventilated, which is exactly the environment that turns a minor chemical error into a hospital visit.

Coughing, burning eyes, chest tightness and shortness of breath. Leave the room immediately, ventilate it, and seek medical advice if symptoms persist.
Sparingly and deliberately, where a situation calls for it. Most routine work is done with non-chlorine products chosen for the surface.
