Before and After - Fuji S3 Pro sensor clean

Recently acquired an old Fuji Finepix S3 Pro DSLR camera. Several years old and probably never seen any maintenance. Noticed black spots on most but not all the images - have been trying the camera with 3 different lenses and it was far more apparent on certain lenses than others, typically most visible on wider zoom angles and smaller apertures. All this and some Google-assisted deduction led me to believe it was dirt on the actual sensor. (Fuji's so called SuperCCD in this case.)
Finally got my cleaning kit last night and tried it out (more pics of that job later).

Before:

Quite horrible...
and After:

Both pics taken with Nikon AF-S DX 18-55mm "kit" lens - the lens that worst showed the dirt.

Success!
