    Probably removing the emulsion will also remove the subbing layer and prevent further coatings from adhering to the film support. I would go with the fixing washing and drying.

    Scraping will scratch the film.

    I'm not sure what your purpose is, but fixing will only remove the silver from the emulsion, not remove the emulsion from the base. Am I correct?

    If you actually wish to remove the emulsion in its entirety, try hot water, very hot water. Gelatin should dissolve in hot water.

    I got my darkroom solutions mixed up once and dunked developed negatives in straight Clorox for about 30-seconds rather than fixer. There was no trace of an image left.

    You should use hot water at aprox. 80 degree Celsius. Put film inside and then gently rub all emulsion with nails or fingers. It should work.

    Soak in a warm solution of sodium carbonate. This is the same process to do chemical reticulation. If you reticulate too long the emulsion just slides off without scrubbing and avoids scratching the film base. Plus-X, Tri-X and other older films work well. Newer T-grain emulsions are very hard to remove.

    Clorox is easiest and quickest.
