We have some tips here:

The next step would either be to attempt a physical cleaning, or get a professional cleaning.

Pentax actually makes the best solution themselves:

If you still have your RAW files, then Pentax DCU has a 'spotting' tool that is very effective and just requires you to set the size of the spot and click on the dust spot in the image. I presume that Lightroom and other processing tools do the same. (find 'spotting' button on the tool bar)
I second dcshooter above. The 'gumby' wand works wonders - it also seems to prevent future dust build up. After cleaning my K10d which had been attracting dust no end, it stayed much more clean for longer.

I've tried a few options and in my view Pentax's cleaning kit, as mentioned by dcshooter above, is both the easiest, safest, and most effective. After blowing off all "resting" dust, the sticky pads have lifted off all I've come across.

Using a loupe to view the dust helps too, but to be honest a bright lamp and perhaps a hand lens is not that more difficult to manipulate.

I'm happy someone asked this, it's something that's been on my mind, but I keep forgetting to search! With my K-3 on the way, I'm not as worried about sensor damage on my very dusty K-r.

Adam, looking at the guide, do I really need both the bristle brush and the cleaning swabs?

O-ICK1 seems an easy part number to remember. Was this on purpose?

I think it would make things easier, but even a basic kit can get the job done if the dust isn't stubborn.

Thanks everyone for the good advice. Before ordering a cleaning kit, i gave the air rocket one more try and think l got the dust removed. I set my lens to 16mm and camera to manual, f11 and took a picture of a white wall and could not see any spots.

That's good news. Personally, I find higher f stops better than f11 to see dust in many cases and also, as well as white walls a clear blue sky works well. I often just take an f22 shot of a clear blue sky when I'm out shooting, if I can, so I can spot any dust early and not let it accumulate.
