You can buy several rubber stoppers that you will use to unscrew the front retaining (trim) ring, You will need to hollow out the center so that the stopper does not touch the front element. You can refer to this page (rokkor 58mm lens) for guidance. http://www.pbase.com/pganzel/58mm_rokkor_disassembly
To access the elements behind the aperture you may have to disassemble the rear mount. For this you need a good set of jeweler screw drivers. Or those elements just unscrew.
You may also be able to find parts diagrams online for you lenses that will guide you too.
From personal experience you will want to work on a tray that will contain any little parts that get away. I also found that if I magnetized my screwdriver, it helped keep the screws and other small parts from going a stray.
Thomas Tomosy Product Image Camera Maintenance & Repair, Book 1, would be a great resource to have on hand. @ amazon for ~$20.00 used

Thanks, Tom, this is a great start. I already know how to TREAT fungus & haze (been collecting data for a long time) it\'s just the \"getting to it\" that worries me. I have read about the Tomosy book elsewhere as well, so this now sounds like a no-brainer. I\'ll order it tonight.
As for tools, that a really tough one: As I wrtoe above, how do I know WHICH tools I need. For instance, that rubber stopper may work on the Rokkor, but don\'t I need a spanner for most lenses? - And then, do I need all three tips, or just the basic spanner? For jewlers screwdrivers, I already have a small but quality set. Yet, none of them work on my Minolta lenses, nor on my Mamiyas. so, must I buy the $240 complete set, or can I get by with a $40 smaller set? How the heck does one figure this out?
