For three years now I have been making and storing my CS in one gallon clear glass jugs.So far they are as clear as the day I started;at least to the naked eye.I have a clear glass beaker of approx 8 oz. size in which I put one of my first batch samples to age,two plus years ago.It is as clear as the day it was put there. For just potable water,after distilling,I put approx. 35/40 drops of mineral concentrace to bring up the acidity to 7.2 to 7.4 PH.;and this is kept in clear glass bottles until used.None of these four one gallon jugs have any evidence of etching.
