Here is a method that can be adapted for your use but is tried and tested.

Thanks for posting JK. :bowing:

A couple of points I feel need adding...

Use of canned air should be treated with care, some canned air may eject liquid or tiny particles of ice, which may leave marks that can be very difficult to remove. Always use the can in an upright position and test on a window or piece of glass first, especially with a new can.

While the process described is to clean the sensor, it is also very important to brush out any dust or fluff from the mirror chamber with a very clean, soft brush, followed by a blow out with clean air. The mirror flapping up and down will soon shift any dust in the mirror chamber onto the freshly cleaned sensor.

It is always good practice to store and transport cameras lens face down, so any dust or particles in the mirror chamber settle on the front parts of the mirror chamber and not on the shutter, right next to the sensor.

Yes good points Robert.

I use the ReAir system which is now defunct.
It is a small compressor (bicycle pump with filter inlet), and a reuseable (repumpd) spray canister.

It is very eco-friendly and does not have liquid propellant gas.

I find that since I use so little solvent these days that I seldom need the ReAir but a Giotto Rocket blower is more than enough.

There are two types of Giotto blower.  The basic one does NOT have a filter, the Rocket does!  Very important that you blow with clean air!

I have the Rocket Blower, very good, I also use it to clean my iPhone charging connector.

I like the canister you found... Very nifty, could charge it up from my garage compressor, I'm sure it would be more than sufficient to do the job. My only slight concern is the ability to easily point the nozzle accurately compared with a lightweight blow nozzle on a soft hose like an air brush.

Thought you would like it.

I would immediately put some silicone tubing over the nozzle and extend by 1cm. Less scratch hazard!
