    If I get water marks on negatives I soak them again in Wetting agent for a minute or so, shake the film and if it 120 I simply hang it up to dry, if it is 35mm I hang it up, take a sheet of kitchen towel folded and wipe the shiny side of the film, turn the folded towel over and wipe the film twice more, never get a drying mark and never get a scratch, whatever you do NEVER, NEVER,EVER WIPE THE EMULSION SIDE of the film with anything, fingers, towel as as sure as eggs are eggs you will get a scratch

    I was wondering whether a final swap/rinse in very dilute hydrochloric acid would do the trick, it would dissolve all the calcium and leave no residue by itself as it is a gas. Has anyone tried this?

    De-ionised water as a final rinse for 30 seconds will ensure no drying marks.

    If you have hard water marks washing in stop bath will usually remove them. Then wash as usual. I have hard to very hard water so I always do a final rinse in distilled water after washing. It costs something but it saves me a lot of grief with water marks. I would not try HCl as it might dissolve the hard water stain as well as damaging the gelatine.
