Internal dust in camera and zoom lenses

@desertguy use the self cleaning function on your camera for the sensor. Follow the instructions on here If you cannot remove dirt or dust on the image sensor (CMOS) even by using the sensor cleaning function on your camera, or if your camera does not have a function for sensor cleaning, you can clean the sensor on your own by using a commercially available blower.

Your lenses are a different story. For that we would need to know exactly what lens you have to see if there are manuals available since you will have to disassemble those in a clean room.
