OK, sorry. Couldn't resist!
I've owned several bodies that required routine cleaning. Some more than others. Older bodies needed it more than newer bodies. My old favorite 5Dc was notorious for sensor specks.
It's my opinion that static is the major culprit for sensor dust and the older cameras didn't mitigate it as effectively I guess because my newer cameras (5D3, 6D, 60D, etc.) don't seem to need cleaning as often.
My thoughts on this is that one should always check the sensor image (various methods either by zooming or using photoshop layers) to inspect for spots in the image after shooting the blue sky, etc at a small aperture.
The sensor should only be cleaned IF it is needed. But once it is needed, a photographer should learn to do it.
It's not much more complicated than simple brain surgery. And when doing brain surgery, it's best to not smoke, play with the cat or be around a running belt sander or chain saw.
Like surgery, you should be clean, maybe wear a hair net or hat and work in a fairly sterile environment. The bathroom or kitchen might be a good idea as long as it's clean, you aren't baking bread or creating dust from rolling 50 feet of TP out on the floor. Get the area a bit humid by running some hot water for while. This will eliminate air born dust and reduce residual static.
Once the environment is set, use your favorite method. Personally I start with a similar method to above where I try to clean the mount, mirror, etc first and then work my way to the sensor. Then I start with air, test for spots, try dry methods and check again. I only use a wet method as a last resort because it's such a PITA to end up with a pristine sensor.
When cleaning, you may find that static is your friend if it's built up on the dry brush you're using.
Whatever happens, just be gentle. You're NOT touching the sensor, you're cleaning the thin glass filter on top of it. It's fairly durable and repairable but if you're careful, you don't have much to worry about other than uttering profanity when success eludes you after the 10th go around.
