Here's another tip. There is this stuff called Chip Quik. It is like solder-however, the melting point is much lower. So you "solder" this stuff onto your joints. Then heat up all joints simultaneously by lying your iron somewhat sideways. Because the Chip Quik stays molten longer, you have more time to melt all the joints. Highly recommended for difficult desoldering jobs. I have the pumps and the braids, and the Chip Quik is way better for tough jobs.
