I've stored conc. HCl in HDPE bottles (what else is there ?), and
noticed thin film of white salt near the lid opening after some months.
I normally just rinse it off, and ignore it, but I'm intruded as what it
can be. I know these bottles do not seal perfectly on the lid, so
microscopic amounts of escaping HCl is inevitable. Wetted salts have a
nasty habit of creeping through gaps and opening them up wider.
If your getting salt on the container body then use better bottles. I've
never seen this happen, except my 70% nitric acid. Its in one of those
black 'poison' labeled HDPE bottles and its continuously wet on the outside.
