Sensor dust?

So while using my 5D on a recent trip, I noticed there was a spec of dust (a mark) on the pictures. I checked the lenses and they were clean. I also look at the sensor and it looked clean (from what I can see with my naked eyes). It's definitely on the picture. How do I go about removing it? Any help is appreciated. Thanks!

There's no way you can see dust on the sensor with your naked eye unless it was an eyelash or something huge. First use a blower (not compressed air) then try one of the methods floating around the forum. I use Sensorklear because it's not wet and does a great job of getting rid of the dust.

I've used the Copperhill method (wet), but could hardly get the pads to work for me.

A Rocket Blower should be your first purchase! That will get rid of 99% of the dust...after that...go with some of the other popular ones (wet or dry wipes)

Suggest search sensor cleaning and decide for yourself which method and if you want to do it yourself. If you only have 1 spot very easy to clone it out in post processing. Chance it may move on it's own. Also a chance rocket blower will move it but move some other dust around inside the camera onto the sensor.
Like I said, if only 1 spot. Of course, dust spots vary, some are small and faint, some are big and dark so that makes a difference regarding working around it.

I forgot about this thread until now. Thank you for all the suggestions/comments! I'll purchase a rocket blower and try that out.

The blower should be the first thing you try. A good blower is worth it's weight in gold and should always be on hand.

Sometimes, however, you will need more drastic measures.
Personally, I like the Sensor Swab and Eclipse method. The link amfoto1 provided, should have a simple guide on how to go about it
