The latest: This is how I am safely cleaning my Leica M10 sensor safely, and successfully. Dust is a fact of life with digital camera sensors. It is always going to happen, and dust will get onto your sensor even if you never change a lens, it will find a way to get in there. I use a combination of the rocket blower, and VSGO sensor swabs. I tend to blow off the sensor with the blower for minor duct, or to remove any coarse particles, but will always use the VSGO for when there is a fair bit of dust on the sensor, or if it seems like oil from the shutter has ended up on there.

Obviously the Leica M10 is a very expensive camera. I want to be sure that I do this right, don't damage my sensor, and clean it effectively so I can continue shooting without dark spots on my images that I have to remove later on.
