Also, pointed dental picks don't work well because there's too much
room for the solder in the hole with the tapered tip. Use a paper
clip or stainless piece of wire instead.

sounds like a job for Chip-Quik or other low-melting-point solder.

I've never tried the stuff. The problem is that dross (oxidized
solder) will not flow, wick, or can be easily blown through the hole.
All that's really needed is some 60-40 and a little flux. Once the
dross is gone or disolved, the solder should flow and the hole clear
easily. Chip-Quik sounds like an interesting way to do a whole IC at
once, but I have a hot air desoldering station that works.
