How to remove dust on Sony NEX camera sensor ?

When you see some shadow on your image and it does not go away! Relax, it must be the dusts, just like what happen to mine. Check out the sample picture with dust below:

 All you need to do is remove the dust by blowing it with this rubber blower (You have to remove the lens first of course). Then, your good to go! Sometimes your dust can  only be detected when you you use small aperture ie. f22. The easiest way to check this is to put in set it to f22 and then zoom at the white cloud.

Oh yes, I did try the sensor cleaning feature, but it seems to be ineffective against stuborn dust.
