Fender Stratocaster Fret Level

This Strat came in with some fret buzz. On inspection I noticed the frets around the 12th were worn and very flat and so a fret level was in order. You can see where the low spots are in the photos where the blue ink remains.

The previous owner of this guitar had used some kind of grease on the tuners which had become sticky and left a residue on your fingers whenever you tuned. The owner asked me to clean them which ended up being no easy task.
