Who would have thought that Pond's Cold Cream would do the job? Here's the proof: kameraking.blogspot.co.uk/2015/03/prism-cleaning-fungus-removal-with.html

Why is it not highlighting?

Thanks Brian, but I've tried that and it hasn't worked. As the link shows, Pond's cream is effective at removing fungus, but there's then the problem of recollimating binoculars once a prism's been disturbed.
Of course, depending on which faces the fungus resides, a prism might not need to be removed, but it almost always seems to be the case that fungus resides at the interfaces of prisms.

Not quite the same problem but........How do you remove the mouldy-musty smell of old books? Many an interesting secondhand books published even as later as 2000, and badly stored, smell really musty and after a quick read I feel obliged NOT to add them to my library. The "foxing" as I believe the brown spots are called, seem to be the main cause. This is particularly obvious on the tops surface of the pages, presumably where spores and dust fall....perhaps that is why, in the past, quality books had "gold" or painted tops. I do not think that this is the same as the "acidy" smell of old newscuttings, the best thing in this case seems to seal these in plastic sleeves. However most modern books are printed on "acid-free" paper. regards maf

I don't store fungused optics with clean optics or musty books and camera cases with fresh ones.
I'd keep them apart or consign to the bin I think.

Regards,
David

I agree entirely. Seems a shame though when I come across a great old book but cannot face retaining it. I have long since given up on anything concerning taking optics apart to clean them inside as I never manage to get them back together properly. The only exception might be old opera-glasses, the lenses of which simply unscrew and can be just screwed in again. regards maf
