I used glass, even for multiple 5 gallon storage of DW and silver for years,
but the light weight and freedom from breakage finally lured to HDPE,
especially when Marshall said it was OK.
Distilled water leaches silicon from glass, so possibly will CS, being it is
to little mineralized.
Does anyone know where I can get 5 g. PET bottles?

I'm no chemist, and I really don't understand all the technical
formulations. I had a list at one time but lost a lot of stuff when
Windows decided to eat the partition tables on the hard disk. One
word that comes to mind is phalates or something like that. I just
did a search and can't seem to find the magic incantation that lets
google show the list again.
But I do recall a comment to the effect that the proportion of
different resins used in the manufacturing process is never quite
exact, so there is always an excess of one or another. You can feel
this on the surface of the hdpe jug occasionally. It sometimes has a
slippery feeling.
So the manufacturing process is not really well controlled, and the
distilled water we buy can literally change from one jug to the
next. Ode has said the same thing.
PET bottles that are manufactured to hold distilled water doesn't
seem to have these problems.
But that may not hold true for other PET containers, for example,
those intended to hold spring water. I tried storing cs in all kinds
of different containers and bottles. Some PET bottles that once held
spring water turned the cs deep yellow, but it was a different tint
that you see with cs. Also, there was no Tyndall, so it wasn't AgOH
agglomeration.
