John's device pictured, is a solder sucker. Push the spring loaded end into the tube. Heat the solder connection to liquid, then press the yellow button on the side, to release the spring load plunger, sucking liquid solder into the white tip, left end of picture. This tool usually does a pretty good job of clean-up, especially in small delicate places. The solder once solidified inside the tube, requires the assembly to be broken-down, and cleaned. Safety glasses are always a good idea. Safety meeting of the day.
