Can I clean my own camera?
I have dust just behind the glass on my rear screen, and just inside the view finder. I have had some success removing a small hair from the sensor, dust on the mirror and on the bottom of the prism, but I'm afraid to take anything else apart. Recently I used a lens cleaner inside the body and it left fiber lint on the black felt like material. It is rough to be non reflective. I was able to brush it out with a lens brush but i had a few loose bristles fall out. I was able to get these and then put the lens back on. Some good instructions and the correct tools would help. The camera is at least 2 yrs old and has never been serviced but used a lot.

I was getting spots in images from dust on the sensor. Not the same problem exactly, but in regard to cleaning the inside of the camera, hopefully you only need to blow the dust out. I was advised by a local camera shop that they could clean it for me or I could try a few options on my own. I bought a pro dust blower from them and that solved the problem. I was advised to definitely not use canned air.
iFixit sells the same blower. Dust Blower style Pro. Dust Blower
If that had not cleared up the spots, special one time use swabs were recommended. You buy the size that matches your sensor. They were about $5 each. I don't know if iFixit sells them.
To check if spots are gone, take a picture of the sky.
