In my experience all pins can be sucked clean from tin except pin14 (Gnd).
With the other pins I did the following:
Remove as much solder as possible, (braid, tin-sucker, etc.) then use a small pair of pliers to just wiggle the pin in the hole to loosen it, before pulling the Dallas.
Do this for all pins except 14.
To remove the Dallas you need to heat pin14 while pulling carefully.
I never got pin14 clear from solder, but heating while pulling worked well.
Just my 2cts,
