    Yesterday I processed a roll of motion picture film (it's kodak 5245) in spiral tank. I've used tetenal c41 3 bath kit.

    The neg looks ok but as I expected there are some issues with remjet. I know that in ecn process removing it is one of the first steps. Unfortunately its not an option for me, as I don't have a place where I can dry the film in complete darkness. I've tried wounding wet film, but that does not work with my paterson spirals, the film is to slippery.

    I've removed it with my girlfriends cotton pads after wash after blix. I think it didnt get into the emulsion, but there is some left on the spiral. I did not have time to check if the blix is messed up.

    Is there some other way of cleaning the spiral than using an old toothbrush?

    Is it ok for a film to develop it, stop, optionally wash, scrape off remjet, then dry, rewound on spiral and continue the process? Or alternatively do the scrape-dry-rewound after the blix?

    In the days before I learned to appreciate the benefits of stainless steel reels, there were a few occasions where I had to re-spool wet film onto plastic reels.

    Immerse the film and reel into a pail (or other large container) filled with water at the required temperature. You will find that the film can be loaded quite easily (even in the dark) when it is immersed.

    Thats what I planned to do; I've read the article. However I've seen some particles in water after the wash so I worried that they can damage the emulsion and foul the stab.

    I have never had a problem with the remjet left on the reels. Even used them for processing my black and white work. However if you really want to remove the stuff from your reels latter you could make a batch of prebath and wipe it off them. Formula follows:

    Water 80 to 100 degrees F
    800mL
    Borax (decahydrate)
    20.0g
    Sodium Sulfate
    100g
    Sodium Hydroxide
    1.0g
    Water to make
    1L

    I would recommend that you make a 200mL solution of Sodium Hydroxide in cold water to prevent the solution from boiling and spitting upon the addition of the Hydroxide. After all burns are painful. (but the burnt hand teaches best):D
