Nice dry caked on grease!!! I dunno the best way to clean that out . . . what I did before I installed hydraulic steering was to get a wire brush (Ace Hardware pipe cleaner). I broke off the loop handle end off the pipe cleaner and stuck it into a power drill. It worked pretty well.
There's so much crap in that hole you'll be at it for a while. Put an apron on your v20 before you get busy with the wire brush.
