chris_raney1 Posted November 4, 2010 Share Posted November 4, 2010 <p>I keep a solution of about 6 grams in a brown glass litre bottle diluted with nothing else. I use it for my Maxim Muir paper developer, and it appears to work wonderfully with no preservative, or otherwise. My base chemical is actually an old pound of Kodak's Anti-fog No. 1 purchased at a camera swap over a dozen years ago. <br> So I'm thinking shelf-life is more or less...indefinite. </p> Link to comment Share on other sites More sharing options...
