So I was out shooting the sky today - not sure why, just needed to take photos of something...
All my photos I took had splotches (dust spots) on them, I naturally assumed it was the lens. Cleaned the lens (18-55) (front element, filter, rear element...), no change, so I cleaned another lens (50-200) and tried that on the blue skies, still dust spots. Through the viewfinder I see bits of dust, but different bits than in the photos. Mirror appears clean - not sure where this dust is coming from... I put the camera in sensor cleaning mode (with the mirror-up) and can see visible bits of dust on the sensor, tried dust removal from the menu, then looked at the sensor again, but it still has bits of dust. Now I need to clean the sensor - how do I do this?
TL;DR: How do I clean the sensor?
