Had the same issue, took out the matte/focus screen with the changer
tool I have here since I bought the grid screen, cleaned it with the
ICK-1 (a blower works almost as well) and reinserted it. It is tougher
when the dust is in the prism assembly, so blowing with the screen in
place is a bad idea or so I was told (yo unever know how good advice
is on the internet these days). But what I can tell you from personal
experience is that the Pentax sensor cleaner aka ICK-1 is safe to
gently tough the screen with.

I second Ecke's recommendation. Just take the screen out (you can do
it with a pair of normal tweezers) and use a blower inside the camera.
I've never actually wet-cleaned the focusing screen, as a lens brush
was enough to get the dust off. I do this at least twice a year.
When removing the focusing screen, it may be handy to have on hand:
dust free latex gloves, in case you drop the screen and need to pick it
up by hand
distilled or deionized water, in case things go really wrong and you
need to rinse off the screen
Be wary of the shim behind the focusing screen, if it falls out, it may
take some dexterity to put it back in.
There are good instructions on getting to the focusing screen on the
Katzeye website.
