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,

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.
Thanks guys, I'll try hot water and elbow grease first.

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.
