I came across several old Pentax lenses which have probably been in storage for at least 20 years.
Nothing fancy. There's an 85 mm, a 35 mm, and a standard 50 mm.


They aren't beat up, but when I hold them up and look through them, there appears to be fine bits of dust on inside surfaces, and other very fine "stuff" that almost looks like mini-spider webs.

Is there any way to do interior cleaning of such lenses or should I just dump them?

If it's pretty hopeless, I'll offer them to someone who might want to experiment...
