Sensor Dust

Hi Simon,
I've had KX, KR, K5 and now K3. The dust alert function shows bad solid dirt BUT I too have had events of marks in clear skies.
I use a rocket blower and have found repeated attempts necessary sometimes (if sticky pollen for example it does take a lot) BUT no liquid cleaning kit needed to date.
I face front of camera downward while doing it to hopefully make dislodged stuff fall out of mirror box.
I also use repeat sensor vibrate function repeatedly first AND have sensor clean turned on for startup and turn off on my K3.

Thanks Bill
I have the shake function enabled too. A lot quieter than the one in the K100d Super! I'll give it another go.

I have used the Pentax sensor cleaning kit which works fine when blowing failed (microscopic paint particles from a new mount converter got everywhere!). Just very gingerly touch the sensor with the sticky bud so as not to damage the sensor mount mechanism.

No one has mentioned the Arctic butterfly yet. I have found it really easy and useful

I use an Arctic Butterfly brush eventually.
Mostly I make copious use of the clone tool, and only when I am really fed up with doing that do I set about the sensor.

A few of my photos are showing what I presume is sensor dust.
A small diffuse area that is clear in sky shots.
I have used a rocket blower to no avail.
What I want to ask is how effective the dust alert function is on the K5iis (or equivalent). I have used this and it shows nothing.
Thoughts welcome before I look at getting a cleaning kit!
