Many electronics enthusiasts look on solder removing as a loathsome job. This is especially true of printed circuit boards with narrowly-spaced conductors. Ji-Things which often happen when one is trying to desolder are: - The solder forms bridges between the conductors. - Blobs of solder drop off the board. De-soldering tools or wicks are available commercially, but there is no need to lay out that kind of money. Any work- shop toolbox should yield a really cheap device which will do the trick - a pencil.
