We have had pretty good results using a salt water fixer (300g/L if I remember correctly) - either 48 hours at room temperature and no agitation, or 4h at 45C and constant circulation of the solution (I used a sous vide to do this. It was a bit tricky to keep things light-tight with a sous vide sticking out of the container, but it worked. https://en.wikipedia.org/wiki/Sous_vide). I put test strips of (5222 negatives processed in caffenol and fixed in salt water as described above) in the window for 2 months and the image seemed stable after that amount of time and light exposure. I'm curious, though, what other people's experiences with salt water fixer have been.
