Who says the concentration is going to be "reasonable"

I looked up what bleach & ammonia does together:

and, "in quantity" it would be a bad thing.

But I think safety is a moot point simply because we're talking about
fewer than 5 or 10 drops of bleach on a carpet, which is then soaked
with the un-chlorine solution, whatever that might be.

The purpose is simply to save the carpet - and it would be easy
to vent the fumes, whatever few their may be from the tiny amount
of bleach compared to the amount of un-bleach used.

So far, the 'unbleach' suggestions seems to be:
- Water
- Ammonia
- Sodium sulfide
- Sodium metabisulfite
- Sodium thiosulfate
- ?

Since the solution has to be readily available in the household,
it seems like only the ammonia is something we'd have on hand
were a few drops of bleach to be accidentally spilled on the carpet.

I will try it (OUTSIDE!) on a dyed towel and report back for
the team (with pictures). *(If I don't report back ... )

When we lived in a flat, the carpet was NOT resistant to bleach, a
little bit not only changed the color, but dissolved it! down to the
backing mat. Carpet unknown origin. Presently, we moved into a home
with a high quality, 'mauve' desert colored carpet throughout sections
[big mistake in Arizona environment!] This carpet only slightly
changed color when over half a cup of bleach dripped onto it once
overnight! But since it does change color, for those occasional
spills, we used to use chemicals to 'negate' the bleach but found that
somehow that seemed to accelerate a slight color change. We abandoned
chemicals and went to distilled water, as much and as fast as you can,
then suck up with our carpet clearner - essentially a wet 'n' dry
vacuum. Then do it again. THAT process seems to be the best.
1. pour distilled water onto the spots, wetting ocmpletely.
2. suck up with carpet vacuum [we have a professional unit cost around
$4k, worth its weight in gold]
3. repeat, repeat.
Then use the incident as an excuse to do the whole room, keeps carpet
looking new.
