" but I understand sunlight weakens it? "

Where do you hear such stuff?  Sunlight, if anything, helps keep it oxidized.  The copper isn't going anywhere.  I store mine either in its all glass etching tank or Tupperware plastic.

Stay away from Bakelite lids with paper liners; although, if it has a Teflon or PE liner, it probably is OK.

  anybody have a link to something to store this in? currently in a clear glass jar but I understand sunlight weakens it? I can't find any smaller dark glass jars w/out metal anywhere. meh
