Reminds me of a rhyme from school:
Poor Old [insert name] is dead and gone,
We'll see his/her face no more,
For what s/he thought was H2O
Was H2SO4!
Seriously? What the hell kind of school did you go to, where THAT was a rhyme? And I thought Ring a Ring o' Roses was morbid...
We had the same rhyme at our school.

That would have to be an incredibly strong acid.

I'd doubt that the body was totally dissolved but more likely what was left was not worth the effort to recover. A bit like trying to recover a cow and getting minced beef.
Sure they could recover it all, but that's not going to be financially viable or safe. I'd guess a decision was made to try but they gave up after seeing the extent of the damage.
I'm no chemist but I wouldn't be surprised if the combination of acid & heat would do it though.
Well since what is in the pool is basically very hot industrial drain cleaner which sole purpose is to dissolve hair and tissues in drains, I suspect 24 hours in that pool will have made a sloppy mess.
Okay bones will probably be fine but I can see the point with the rescuers that its not worth the risks to try and recover the remains.
A quick google suggests 24 hrs plus heat is enought to turn a human body to a sludge and has been used by several mexican gangs for body disposal.
Or just very hot water.
It's a pool.of boiling sulphur of acid, 12 is probably plenty long enough to mostly dissolve a body
I work with it, horrible stuff, I've come close to being burnt by it a few times![]()

Not only would it have been a horrific sight to see but seeing him thrash around screaming would have been the hardest part to witness.

A bit long winded, but this might have what your looking for.
This. Suspect she would drop her phone and rush over to try and help him.
