    Removing fixer crud

    hi all, does anyone have any ideas for removing the hard scale like deposits that thiosufate fixers deposit on bottles and trays? A 'recipe' rather than a product would be ideal.

    Thanks,

    J.

    Re: Removing fixer crud

    Hi J,
    I had that same problem in cleaning out my Jobo ATL 2200 fixer bottle.
    I asked a few labs that i work with and they said very hot water and a scrub brush or scouring pad is the best and safest way to go.
    It took some elbow grease but it did work. Also soaking in a number of changes of hot water overnight really helped.

    Some products do exist for cleaning fixer deposits. Im not sure what they are made of.
    Kodak has the KODAK Fixer / Wash System Cleaner and Liberty Photo might have a few also.

    I also found a pdf from Kodak, Removal of Silver Sulfide from Fixer, Bleach-Fix, Wash, or Stabilizer Racks/Rollers in Photographic Processors.

    I think this would work but the hot water and a scrub brush is a lot safer.

    Hope that helps.

    Start out with some very hot water, though not too hot, a few squirts of Lemon Joy and a few glugs of chlorine bleach. Let the tray soak over night and the scrub with a Scotch Brite type product - or just throw the tray out and replace it with a new one.

    I use "Polident for Smokers" in bottles with warm water. Sometimes it takes a couple of treatments. The bottles are then thoroughly rinsed in hot water.
    For trays, I use a dish washing detergent with a Scotch Brite immediately after using the tray.

    The Kodak fixer cleaner is a mixture of EDTA, and an equimolar mix of S. Bicarb and S. Carb.
