Focusing Screen Cleaning

I have taken my camera all over the place and through A LOT of different kinds of environments...and as of right now the focusing screen is sort of dirty and I want to clean it.

What is the best way to clean it is the first question (which products if any) or other things would be helpful...

I also think I might be interested in getting a different style of focusing screen. I mean the one I have now works just fine but I would entertain getting other options to try as well...From what I understand there was another company that made focusing screens but they are no longer in business.

Any relevant information would be helpful.

There are specialised cleaning kits on offer at B&H etc. You may also use one of these ultrasound cleaners that opticians use for glasses, and there is at least one tutorial on the web of how to carefully clean the focusing screen with water and soap.

Whatever you do, do it in a clean environment with little dust. Your bathroom just after someone took a shower would be a good place.

I made the mistake of trying to brush dust off my K3's focusing screen with the soft brush of a lenspen, and completely scratched the thing. The plastic is so soft it is extremely easy to damage, so be careful.

I bought a focussing screen from RICOH for my K3 ML-60 AF Divided Matte.

The little box includes a detailed instruction and a pair of tweezers how to change the focus screen.
When you remove the screen it is very easy to dust of the screen and the prisma with a Rocket blower.
Most of the dust is between the screen and de prisma.

Do not touch the screen.

Definitely don't try! I did and it's knackered! I can put up with the marks, you start to ignore them. I've bought a new one to fit eventually.

Dirty in what way?
My advice is - if you don't have to remove the screen, don't. If it's just dust, try a rocket blower with the screen in place and be careful not to touch the surface.

For alternate screens there are a number of threads on this forum. Search for "focusing screen". Unfortunately the manufacturer with the best reputation (KatzEye) is going out of business.
I have switched the screens on booth my K-5II and K-3 to cut-down Canon screens from with very good results. If you should go ahead and change the screen, be prepared to put in some time to fine tune the front-back focusing with shims of different thickness (available from Richo).

Don't use alcohol. I cleaned the screen on my K50 with Isopropyl and it turned white.
I have ruined a few screens by attempting to clean them. If a Rocket Blower doesn't get it clean and you can't live with the gunk, replace it.
