Sensor Cleaning Steps

Would anyone mind sharing a simple step by step of the M11 sensor cleaning procedure relating to menu items  etc. I use a Rocket Blower on my A7R4 as well as the full sensor cleaning swabs. As the M11 is a fixed sensor it should work with that as well.

Please consult the Leica M FAQ.

Sorry Japp. Not a cool reply. Cameras have different menus settings to access sensor cleaning. If you don't have an M11 maybe not always feel the need to contribute.

M11 sesnor cleaning settings are located at the bottom of the camera settings section (page 4 of the menu). You select sensor cleaning and then YES. Turn the camera off after cleaning.

thank you for your reply...so I imagine that that setting opens shutter until the camera is turned off? So the cleaning takes place with the power on?

Well, sorry I thought that would be a given and set out in the manual. I supposed that the OP meant the sensor cleaning itself which is pretty much identical for any camera. 

BTW   not owning one does not mean never having used one

The shutter opens when you turn the camera on. That setting disables the shutter button so you can't accidentally destroy the shutter and sensor during cleaning.

yeah you say select the sensor cleaning menu, the shutter opens (if it sees to close with no lens) then turn the camera off and theres about a 10s delay

Here is a blog post I wrote back in 2016 on sensor cleaning:

Digital Camera Sensor Cleaning

 

Digital cameras have sensors; unless your camera has a built in dust reduction system, sooner or later your sensor will need to be cleaned - it's inevitable.  Then what?? 

It's a lot quicker, easier and less costly to do it yourself - if you follow your camera manual instructions exactly and are careful, you can successfully clean your camera's sensor yourself.  A lot of photographers fear damaging their sensor and will do about anything to avoid cleaning it themselves.  However, there is no reason to be afraid to do this procedure yourself, provided you do it properly.

You will need the right sensor cleaning supplies - I use Eclipse Optic Cleaning Fluid and Photosol Sensorswab Ultra sensor cleaning swabs.  If your camera has a full frame (24x36mm ) sensor, you will need the Type 3 swabs; they are 24 mm wide, as is your sensor.  APS-C and smaller sensors will need smaller swabs.  Photosol's website has information that will help you determine which swab is right for your camera.

One of the most important factors in successful sensor cleaning is to perform this procedure in a clean, dust free environment.  Not many of us have access to a clean room such as computer manufacturers build computers in.  If your home has airborne dust issues you will need to clean your sensor in an environment where dust is less of a problem (you can check for airborne dust by looking through the beam of a bright flashlight at night; if you see a lot of dust particles dancing in the air, you should probably go elsewhere to clean your sensor).  Where would that be?  Try a museum or a library; find a spot away from frequent foot traffic, entries and exits and away from heating and cooling ducts that will cause airflow that will stir up any dust that may be present.. 

Another important point is this - do not use compressed air ("canned air") to blow dust from your sensor before cleaning.  Canned air can spray liquid propellant onto your sensor cover glass, something you do not want to happen.  That liquid can also get behind the sensor and into the electronic components of your camera.  If that happens, you are in for a serious repair bill.  Instead of canned air, use a blower bulb like the Giottos Rocket Blaster, which will safely remove loose dust particles from your sensor.

The sensor swabs I use are dry, which means I need to apply the proper cleaning fluid to them before use.  Too much cleaning fluid can damage the electronics inside your camera, so proceed with caution.  I have found that four drops on the 24mm wide swabs my camera requires is sufficient (two drops on one side and two more drops on the opposite side); apply the fluid at the cleaning edge of the swab and hold it cleaning edge up for 10 seconds to allow the fluid to uniformly wick throughout the cleaning edge of the swab.  Again, follow the directions that come with your swabs and cleaning fluid to the letter.

Each camera has a specific procedure for sensor cleaning; if you precisely adhere to the instructions in your camera manual, you should have a successful sensor cleaning result.  If there are still spots on your sensor after cleaning, you can re-clean the sensor provided your camera manual does not advise against doing so (I once ended up with an eyelash on my sensor that required two cleanings to remove; the first try simply moved it closer to the center of the sensor; this happens sometimes).

If you follow the directions in your camera manual and in your swab and cleaning fluid to the letter, you should have no problems cleaning your sensor at home (or at your local museum or library, if need be).

The above description of sensor cleaning is simply a description of how I clean my sensor; it is not intended as training or professional advice in sensor cleaning.  Always follow the directions in your camera manual and in your sensor cleaning materials to the letter.  When in doubt, contact your camera manufacturer for advice on sensor cleaning, or return your camera to the manufacturer's repair department for sensor cleaning.  The author accepts no responsibility for any damage resulting from do it yourself sensor cleaning.  When in doubt, contact your camera manufacturer to return your camera to the manufacturer's repair department for professional sensor cleaning.

thank you all for the helpful replies.. I was able to clean the dust using the menu option and a Rocket Blower.
