Akira:
Fortunately, I've never been in need of cleaning sensors with swabs, wet or dry.  I've been successful to blow off all the dust particles on sensors using KOH HEPA JET 2:

Thanks for the link Akira.  Does the Koh Hepa Jet2 also works for sticky particles on the sensor ?  I once bought a camera which had that problem.

You are welcome, John.  Hepa Jet 2 is nothing but a blower even with the hospital-grade dust filter that keeps the blower from blowing dust towards the sensor along with the air.  It may work for the particles of weaker stickiness but would not for really sticky particles.  The blower is large, but the air flow is a bit weakened by the efficient HEPA filter.

My SIGMA fp suffers from the rolling shutter effect, but instead enjoys the total lack of mechanical parts that have been the main source of the dusts rather than the dusts coming from outside the camera.

Thank you all for the useful information. I guess I just have to take a plunge and try it...

Anthony:
I have had no success with blowers.

I use PecPads wrapped on a soft plastic spatula, and Eclipse. There is a version of Eclipse which is supposed to be flight safe. I find it hard to believe that a small bottle of regular Eclipse in the middle of my suitcase is a fire risk on a flight.

I use an Ezclean sensor loupe to check for dust https://www.cameraclean.co.uk/p/ezklean-sensor-loupe/. I have the Visible Dust loupe but find it useless.

But the only truly effective way to check is to shoot a clear image (eg the sky at f22 or thereabouts) and view the image on the screen, increasing contrast to get a more accurate impression.

I had a series of photos with lots of dust and found that the easiest way to deal with this was to use Photoshop's Spot Healing Brush on the first image, recording the applications as an Action, and then running the action on every image which was affected. It worked very well. But cleaning in advance is better.
