Please refer to this thread for more info about stabilizers and/or final rinses: https://www.photrio.com/forum/threads/the-definitive-word-i-hope-on-color-stabilzers.89149/unread

I remember this thing from a long time ago. Never fully read it.
Thing is that a lot of manufacturers are a bit discrete on the function of this and it's composition. At least in my third party kit, there isn't a lot of information. It even comes as a strange white powder in a tiny zip bag...

After that bath, I have to photo-flo the film in order to avoid white streaks on the film. Not a great thing to have on my negs.

Yeah, anyone can pretty much in there whatever they feel like. Personally, I never use the final bath from any manufacturer and just dip the film in a photoflo solution. No preservatives etc., just flo. Fingers crossed for the long term, but knowing what I photograph, I don't think it's a major loss if the negatives happen to rot in a decade or two :smile:

That's pretty much what I've been doing. I just give it a soak in the stab to have a clean conscience. After that I sometime do a quick water dip before putting on the photo-flo with a spray bottle (my favorite way of doing it) and wiping between my fingers.
And like you said, most of us are definitely not the Ansels of the world...

If you're doing another rinse after the stab/final rinse, you might as well just skip the stab/final rinse.

I figure that what gets absorbed by the gelatin is probably enough. The quick rinse is mostly to about getting some of that stuff off the surface so it doesn't get on my skin.

There seem to be a number of people out there who don't think it is necessary to keep negatives once they have been scanned. For those people, this would be fine.
Final Rinse contains the same or similar surfactants as PhotoFlo does, so it fulfils that part of PhotoFlo's role.
For clarity, the bactericide is only necessary in colour and black and white C-41 processed negatives, because the C-41 process removes the silver from film.
Processed "normal" black and white film still has silver in it, and silver itself is an excellent bactericide.

This post got me thinking about the long-term effects of bactericide, more in connection with film that is later scanned using a fluid-mount method. It's my understanding that one of the more widely used fluids for this consists primarily of naphtha along with mineral spirits--at least that's what I use. What affect does this have with the bactericide on the film? Does it wash it off? If so, what does this mean for long-term considerations of the negative?

Good question. But I personally wouldn't worry about it as the companies that produce the mounting fluid should know what they're doing, especially if they sell to museums.
