After using my camera (Pentax K-x) for over a year, I've noticed dust spots appearing on my photos. Did some reading up and found out that those were dust on the sensor. The recommended cleaning methods are sending back to the service centres or buying cleaning kits (swaps, brushes etc) specially made for sensor cleaning. But these are rather expensive (to me).
Not wanting to spend too much to clean up the dust, i searched online for 'cheap' cleaning methods.
First the easiest way, use blower to blow.. I squeezed till hand tired.. but the dust are still there.
Then I saw recommendation to use 3m scotch tape on the sensor. A few websites recommended this method and there are also a few youtube videos showing how to do it. Well it seems rather easy and effective. So i bought 3m scotch tape and tried on the back of a DVD (they recommended to do that to show that there will not be any residue). Truly, the tape picked up the dust from the DVD and leaving no residue, CLEAN.
So, confirm ok.. it's time to do my sensor cleaning with 3m scotch tape. Followed the instruction on the youtube video and .. first dab of the scotch tape on the sensor... saw a line.. dab the tape over the line.. ANOTHER LINE! IT DOES LEAVE RESIDUE! And it's the sticky scotch tape residue! Suddenly.. cold sweat started pouring.. is this the end of my camera?!
