    Yes it's perfectly fine but don't blow too hard on it.

    Customised sensor swipes and brushes.

    But of course blower is something simple that one can do first.

    There are cleaners which are made for sensor cleaning, but i don't trust those.

    The problem is, when you blow the dust, where will it end up? As there could be dust particles elsewhere within the body, the airflow could dislodge these particles from within the mirror chamber and fall onto the sensor.

    Plus also, there is a possibility of moving air statically charging the surfaces to attract even more dust.

    I also don't trust swabs. Dust particles can be oily, and swabbing them can leave streaks. I've tried swabs before, following all instructions, but still had streaks running across the surface. The best way for me is to use Kinetronics Speck Grabber (takes some practise to use proficiently), followed by LensPen Sensor Klear.

    Hope this helps.

    air always escape from openings, most likely will come out from the front (lens mount).

    By the way, there's a low pass filter in front of the sensor. So it's perfectly fine to blow the sensor.

    Yes ofcourse can use a blower to clean. Just lock your mirror up first then hold your camera horizontally with the sensor facing down and then blow into it from a distance. The dust particles should fall off. This is the no risk method. Just make sure you dont touch your blower to the sensor!

    The good news is that it's safe. The bad news is that it does nothing to remove the most of the stuck particles. You'd eventually need some direct contact method.

    haha i know there are lots of ways but at least for me, first cut is try blower. if blower doesn't remove the dust then go for direct contact cleaning liao which so far i do not require to do so...
