A cheaper option would be a good quality nylon artist brush. Using a can
of compressed air, give the brush a blast and you've given it a static
charge to lift the dust off of the sensor.
I go for simple and effective
s/. Not cheap, dangerous if you eat it, but the most effective tool I
have seen in the past 50 years or so.
Thanks the solution that I tried worked well this time but it's good to
know that there are other suppliers available if it doesn't another time.
