    ...across slides.
    I know this topic should belong to the color section of this forum but I'm posting here because I hope it gets much more exposure (no pun intended!!!) :smile:
    Here's my problem: as you can see from the crappy image attached (which I've made with my webcam - please don't shoot in my back :smile:), several slides have this white faint line across them.
    I've tried to clean them in every possible way, to no avail.
    What I've tried is:
    1- cleaning with photoflo 1:200
    2- only photoflo with a cotton swab
    3- with an electronic contact cleaner
    4- only distilled water

    The slides have been developed by a professional lab here in Rome, Italy, where I live.
    I can argue the faint line is a stabilizer leftover but I cannot remove it. Ah, last thing: Pec-12 in NOT available here.
    What can I do to salvage these slides?

    Have you checked to see if its a scratch? Is it sharp? Is it intermitten? Have your lab not mount your film to see if its there. If not then have it mounted. If it appears then their mounter maybe a fault.
    It's not a dark line so it can't be a processing mark or scratch.

    Unfortunately is not a scratch, nor it's sharp and neither intermittent.
    It's not definetly a mounting damage, I was more prone to think it's a stabilizer residue but...
    ...how can I remove it?
    Maybe with a 3% formalin solution???

    Try the photo flo or Peck 12 to clean it. If that doesn't work rewash in a warm solution.

    I've tried photo-flo, as you can see from my post, but to no avail.
    Pec-12, same post above, is not available in Italy (and I don't want to order it just for that, it will cost me a fortune in shipping).
    That white line is large in width and it's opalescent, hence I think it's a stabilizer residue left on the non-emulsion side of the slide.
    But I dunno how to remove it...
    I will try warm distilled water @ 38°C to see.
