When nothing else works use a "mild" acid. I have used muriatic acid (pool supply acid) cut at 50%. Soak the reels in the acid for 15 minutes and the reels will be as white and smooth as if new. Just be careful with the acid. This is a last resort when none of the normal methods work. I came...

Well, and this will be my last post on this subject. For anyone who still has an interest in Pan F+ 35mm and a slight pink base stain. I have finally received information from Harman Technologies, Ilford, on the pink stain issue. While I did not get a direct answer from Harman, I did get a well...

Thank you but I did try that during my many posts. I placed a developed roll of film outside for one hour, but held back 5 frames for a baseline. The pink was exactly the same between the sunlit and non lit frames. It was a full sunny day at about 1:00 west coast time.

The last time I posted, I reported I was going to purchase new film and chemistry to confirm the pink base stain wasn't something I was doing or a hidden issue with the chemicals I make from scratch or something wrong with my 100 foot loads of film. Well, just received and tested all new film...

Thank you for the clarification and your time.

John, I have made those tests with a condenser enlarger, with 35mm film, I always print 35mm with a condenser. While I can pick up a difference on a reflection densitometer, using variable contrast paper, that difference is in no way visible to the human eye. The difference in reflection...

This seems to be bugging you as much as me, thank you. I will post back as soon as I know. The first thing Ilford will ask me is the emulsion number. New 35mm film will give Ilford no wiggle room. Again, thank you for your concern.

Thank you for your work and time. Before I contact Ilford I will purchase two new 36 exp. rolls of Pan F from Freestyle Photographic; I am currently using my 6 month old 100 foot rolls that are always frozen. I will test these new 35mm rolls with manufacturers fixer and HCA instead of my own...

I have pulled out old Pan F film from my negative files, the readings are in the high teens, like the discontinued Efke films, Rollei RPX 25 is at .06; the old Pan F films also aren't pink. It really isn't about the .27, it is the pink stain, that stain, in the past, just was not there. My...

First thank you for that information. Next, may I ask where you found that information? I just placed a bag of 36 exp. Pan F in the sunlight, I keep 6 frames in the house as a baseline. The pink is still there, not changed. I put a strip of 5 frames in newly mixed HCA, left in the HCA for 20...

Wow, thank you Andrew, knowing that someone else is seeing this issue is nice to see, thought I was going crazy. I will report back to this thread after I go back and try everything suggested one more time.

It is just after 50 years of being a photographer, pink means poor washing and or fixing. No, the pink isn't causing an issue, just my experience of what, in the past, pink means. Just attempting to have clear film which is what it should be. Won't put too much more work in to this as the pink...

Thank you all for your replies, I will go back and look at the suggestions. My issue is I was the chief photographer for NASA for a little over 20 years. I am very good at diving into photographic problems, I had to be. I have tried acid fix and alkaline fix. I have fixed for as long as 20...

Thank you Earlz for your post.

Not sure I understand, OCD not sure what that is?
