A de-soldering trick from an old gas passer.
Cutting the leads off the IC works well, you use a pair of dikes with narrow jaws and cut the legs right at the body of the IC. What I do next is turn the board over and heat the pad with a low temperature iron then push the cut-off leg out using a dental explorer. Push the explorer all the way through the hole cleaning the hole out. Then turn the board back over and clip the solder mounds off, insert the new IC and, again using a low temperature iron, carefully solder the new IC back in. Fast, reliable and with minimal board damage!
