One thing an old pharmacist (they used to be chemists, right?) once told 
me is to rinse whatever container you are going to use 3 times with the 
solution you will put in it.  I rinse jugs with dilute Clorox first, 
then let any fumes boil off three days before using the container.  
That's before the "3 rinse."

Another thing.  I do some nickel plating, so non-distilled water would 
create a sludge right away.  One warning I received was not to store the 
distilled water more than 6 months.  The plastic jugs are permeable to 
O2.  Heck, at .93/gal, buy some new.  LOL
