D7000: Semi-circle "stain" or "line" in viewfinder | Spots on sensor

I have a weird half circle stain or line in my viewfinder on my D7000. I've had it now for at least a month. I've cleaned my image sensor 2 times now and the images are mostly clean. However, I'm sick of seeing things in my viewfinder. They're distracting.

I purchased a kit with VisibleDust cleaning solution and swabs. They did an okay job on the sensor but not 100%. If the spots on the sensor do not clean up after using the swabs and solution, I assume it's some kind of oil or something like that. Has anyone else had any experience with either issues?

I finished up my kit last night and purchased some Pec-Pads and Eclipse solution as recommended by a podcast I frequent. Hopefully, this will take care of the issue.

In addition to the swabs and solution, the kit came with the Lens pen which I notice uses some kind of weird black ink to clean lenses. I have a feeling this could be the culprit.

As far as the viewfinder goes, do I simply clean the other side of the mirror and that upper plastic shield above the mirror?

Thanks and sorry in advance for the disorganized post,
Bryan
