Dust

I just noticed some dust spots when I look through my view finder. They are not on the lens because when I remove it they are still there. I wiped the view finder and they are still there. They do NOT show up on any pictures so I don't think they are on the sensor. Where can they be and how can I clean it?

I would remind you of the old saying"If it ain't broke don't fix it". If it works and isn't giving you trouble , personally, I would leave it alone, Jeff

Could be dust on the mirror. I would google a DIY but if you are still uncomfortable I would take it to a camera shop.
