You must be using some very old solder with huge flux core. I have never
experience this problem in decades of soldering.

A note to all:
when you use rosin (or any other core filled) solder, you should always
"crimp" the ends to prevent the rosin from falling out of the solder.
Many times while helping others solder a board I've had to "melt back"
the solder until I found rosin in the center/core. Thus, explaining why
they were unable to get the solder to flow and a proper connection.
