Nuts. It doesn't need fresh solder, it needs fresh flux. The fresh
solder contains the flux, but it also contains a healthy dose of what
you're trying to remove. Much better to just add a drop of flux.

One might think that this would suffice, but in practice, it is
often necessary to add a little rosin-core solder to permit
wicking and better interface to the suction head. I have found
adding flux often just gums up the tip when there is insufficient
solder in the joint. This condition most often occurs for me
on large lands with heavy conductors.
