Don't try to clean is my best advice, not that it is helpfull though.
I use the artic butterfly and that works quite well for both aslong as it is just dust, won't do too much with it.

Don't try and clean the mirror! leave that well alone. Cleaning the sensor with the right equipment is not a problem not is cleaning the focussing screen, which you can after all remove if you have the right tweezers, but never ever touch the mirror.
Since the dust doesn't affect the photos you take I'd leave well alone.

The LX focussing screen was easy to remove with the tweezers and it was built like a tank anyway, but I suspect the electronic K20d is a little bit more 'sensitive' which is why I asked.
I wouldn't touch the mirror as I wouldn't wish to disrupt the fine balance

The screen scratches easily, as I found out when mine fell out into the mirror box earlier this year!
If you MUST clean it then treat it as you did the LX, but don't use Mr Sheen as Karl suggests, the dish washer maybe...

That's the point, the LX was built like a Sherman tank so I was less fearful. I am hoping the K7 will inherit some of that invincibility - that would be nice.

The screens are very soft and should not be touched. The mirror assembly can easily be knocked out of register and should also be left well alone.
This applies to all SLRs though, the LX included, so it's not the case that the DSLRs are more vulnerable in this respect.

I was just talking about general handling but I agree

I would recommend the Arctic Butterfly but would be very careful. The likelihood is that the dust spec(s) are on the underside of your focus screen.
As everyone as pointed out however if they are minor I would leave them as they don't affect your images.
