Chlorine + ammonia = ammonium chloride (possibly other nasty stuff). Bleach
bottles usually have a warning about mixing bleach with other cleaning
agents, in particular those containing ammonia.

Close but not quite. Ammonium chloride is a fairly harmless and
non-volatile salt. I suppose that could be an ultimate product, but
not the major problem.

Bleach + ammonia -- CHLORINE GAS which will indeed ruin your day.
This could be the same reaction a previous poster mentioned about
putting bleach on pee - if the pee has broken down to ammonia OR there
are nitrogen compounds in the pee that react similarly, you could get
chlorine gas from that too.

Had a Zenith console that was moused, I used some kind of cheap dollar
store lavender flavored cleaner spray on it just to get the dirt off
before going after the smell. Now whenever I use that stuff, I have a
nausea reminiscent of the mouse pee. Turns out much of what I was
smelling was the cheap perfume in the cleaning product, blended with
pee. That product is now forever associated with mouse pee in my
olfactory memory.

Another funny story: I do some volunteer work in a barely-occupied
warehouse, and the bathrooms hadn't been used forever. One night I
poured sudsy ammonia in the urinals to let them soak. Next day
another volunteer decides to go in there with a bottle of bleach! :-o
He was not a happy man when the green chlorine fumes started wafting
up.
