Braving the Perils of Guitar Maintenance

So, I've been telling myself forever that I needed to clean up my acoustic, but today I
finally did it! HAHA!! Actually, it started out as adjusting the truss rod in order to
lower the string height, but I started reading online and found out that a better way to
do that would be to remove the saddle from the bridge and file down the bottom,
thereby lowering the strings. As I did that, I went ahead and cleaned it up while the
strings were off.
  First, I took the strings off and pulled the saddle out:

Next step was to get the gunk off with some fine steel wool:

I got some almond oil to rub into the fretboard, and let it dry for a while. 

Re-stringing...

...and Voila!
