If you're as afraid as I am of messing up the sensor and if you're just half as much of a klutz as I am, you also might have understandably been as hesitant as I have been to clean the sensor on your own. After paying USD $75 each time to have my sensor cleaned when using a dust blower didn't complete the job, I finally became unwarrantedly brave and purchased the SensorKlear Loupe kit by LensPen. Much to my surprise, everything worked both effectively and extremely easily.
The primary advantage of the loupe is that it very brightly lights the entire sensor, making it very easy to see foreign materials. It also has a large opening in the side that allows you to insert a LensPen to either remove the dust from the sensor or at least loosen it sufficiently to remove it afterward with a blower. The kit comes with the loupe, the LensPen, a blower, batteries and a soft pouch.
I especially like that I can now clean my sensor when I'm hiking in a remote area every day and don't have the luxury of turning my camera over to a shop for a few days to get the sensor cleaned.
I'll be sure to check for dust on a regular basis, hoping to remove it before it becomes stuck to the sensor. Despite my uncharacteristic, recently acquired bravery, I'm not about to go near the sensor with a wet-cleaning process.
