Cleaning the Camera Sensor

-Removed the lens and set the camera (EOS 30D and 300D) to "sensor cleaning " mode - locked the mirror up!
-used a free credit card (that come in mails that you are pre-qualified etc etc) and cut it longitudinally like a popsickle stick... (14mm wide- width of the sensor is 15mm);
-wrapped a soft lens cleaning tissue over it, and taped it;
-dipped it in Methanol;
-cleaned the sensor in one stroke ;

-next stroke: another tissue (dipped in methanol)

-finally: using a forceps I picked a piece of tissue, wrapped it around the forceps and taped it, and wiped the sensor (dipped in methanol, of course)

Voila!!
