I do have some expired film and paper and always want to try to use Benzotriazole to reduce their fog.

I came across an article on on DIYPhotography.net where the author using a combination of Benzotriazole, lower developing time and longer developing time to suppress the fog on his expired film.

So I thought I gave this a go using some expired Fomapan 400 film on a 8x10 camera.
