I have given up on benzotriazole. Using a ferricyanide rehalogenating bleach (and then re-fixing) after dev and fix has allowed me to use old paper with quite pronounced fog, with very good results.
This is a great way to save old papers if you normally add density or even flash the paper to give the bleach something to "eat".
But with lith papers so hard to come by, and so wonderful with even badly fogged papers... don't trash it or waste it if it liths, someone will pay for it!
And lord, Brovira is a freaking fabulous lith paper. The matte is pretty damn glorious, the gloss really has some balls, so to speak - just punchy blacks and contrast.
I had an opened box of paper given to me which, when I tried to make conventional prints with them, looked crappy. So I took some negatives of old-looking subjects that I wouldn't have ordinarily printed, and used the old paper to print them. They are not masterpieces but they are interesting
