So... got some important negs back from my usual lab. Been scanning them, and they have little white dots all over -- the kind I typically associate with insufficient fixing or washing.
It's been ages since I've mixed up any C41 chemistry and honestly I forget a lot about it. What's the best way for me to re-wash/re-fix these negs?

I would just rewash them and if possible put them in some stabiliser.

Containated fix. Silver preciptates out and gets on the next film. It can be removed if it does not dry, not after.
Fix is fix. Try a frame or two in a dish. rewash and STABALIZE or the color will fade. If no stab, then scan and fix with photoshop.

^^ Ronald, thank you. I think with this work I'm going to stick to the digital solution... Am I right to assume that silver precipitates don't harm the archival quality as much as exhausted fix would?
I think I need a new lab...

Without seeing negs, labs are struggling with low volume. The processes were never made for low volume.
With monochrome at home, fixer used one time will have silver particles
in the bottom after 48 hours. Therefore I consider it one time use.
Doing more films at one time is more cost efficient .
I have tried everything under the sun to filter them out except a centrifuge. Nothing works.
You need a volume lab.

Are we talking particles of metallic/amorph silver or particles of a silver compound? If it is indeed particles of silver then it should be possible to remove them by re-bleaching and re-fixing the film, no? Both steps will not harm the film, so it is at least worth a try.
