First time cleaning up a scan via GIMP. Since GIMP doesn't have a easy way to get rid of noise/jpeg artifacts like photoshop; so I had to use selective Gaussian blur as a means of getting rid of noise.

Funny you mentioned that since i had G'mic already installed, but at the time couldn't get it to run. GIMP would open, give me an error message about it, and then GIMP ran without it. After re-download & re-installing it for a third time it finally works. Now I got to figure out how to use g'mic.
Smooth (Patch Based) Use the default settings without 'Fast Approximation' Works well on a lot of images.

Watch out for 'haloing' on some of the other repair filters though.
