Marc, I am with you on the use of blower, and I highly recommend the blower as it solves my dust problem for most cases. Giottos has two sizes and I have both
I have the smaller one in my camera bag and the bigger one at home for the tougher job. The bigger one is stronger. If you watch the Curt Fargo's demonstration of the wet method, he uses the bigger blower and he uses it with a swift motion across the sensor. I prefer to hold the camera facing downward and puff air from below in a swift motion across the sensor. I leave the blower tip at about 1" to 2" clearance from the lens mount. I will recommend the blower as the 1st method to attempt and use the wet method in combination with the blower only as a last resort when needed.
When I bought the big Giottos blower from micor-tools, Curt wraps it in a strong industrial plastic bag to seal the blower and he recommends a clean storage for the blower for the obvious reason in avoiding dust accumulation in the blower.
There are cases that the dust or pollen are sticky on the sensor and repeated trials on using both blowers fail to remove the dust, and I use the wet method as the last resort. For most of my needs, the blower works.
Thanks,
Hin

Wheatfield, I am no expert on this area. But if I hear some contradicting discussions, I rather give out the warning to forum members. I am no chemist but if not the proper type and mis-use of canned air, things can happen
As for the blower, I already give out the warning to stay far from the chamber, what other precautions should we give. Every source that I learn from, the blower is the most effective dry method that is known to be safe. If I leave the blower tip with 1 to 2 inches from, I don't see the harm that you see.
In my opinion, a combination of blower with wet method does the job very well for me.
Thanks,
Hin

I did the cleaning myself. I wrote up two blog post for the cleaning with YouTube video's that I gather
- Sensor dust cleaning with Giottos Rocket Blower
-- try the bigger blower first
-- learn from the video
-- use tripod with camera facing down
-- keep the blower tip at a good distance like 1-2 inches away, don't ever get too close
-- my preferred method for dust cleaning, solve 90% of my need
-- please research on canned air, improper use may risk damaging components
--
- Sensor cleaning the Wet Method with Curt Fargo
-- read all documents before
-- research and access the risk
-- links provided in the blog to the cleaning toolkit that I bought from micro-tools
-- I chose the economical one with Eclipse-E2 sensor solution that are safe for CMOS sensor on K20D, other models as in k10D/K200D may differ
-- I chose the cheaper version with SensorWand and pec*pad,
-- SensorWand can be re-used and pec*pad is cheap in a 100 sheets in the pacakge
-- Sensor Swab will be more costly but they are pre-made for each sensor size
-- I used rubber band (or simply tape) to wrap a single pec*pad sheet around the SensorWand
-- Use this as a last resort as risk is involved, alternative is to Pentax Service
The collected videos are very helpful. It is kind of nerve wrecking for the first time. I have upgraded my rocket blower to be the bigger one and for the life of me, a sticky pollen or dust refuses to leave. And I finally researched and found Curt Fargo's company selling all sorts of wonderful cleaning stuff. His video is worth seeing.
Thanks,
Hin
