I have heard of using canned air to blow the solder out and crystallize it, but I don't think I would try this. I use a heat gun and pair of IC tweezers. Whatever you do, add some solder paste so it reflows first. Ideally you should use a tip for the PLCC that concentrates the heat on the legs of the chip and doesn't overheat the chip itself. Take a look at the temp ratings of the chip if you use the heatgun approach. Most chips are only rated to take that kind of heat a little longer than it takes to reflow the solder.

I had this idea on how to remove the chip easily, but I haven't tried it. Just get some strong epoxy and glue onto the top surface of the flashrom something to act as a handle. After it's dry, use that to pull the chip out.
Instead of epoxy you might use hot-glue (or whats it called), or, even better, "Power Strip" - a removable 2-side-glue flexible tape...
It's a good idea, but keep in mind that some programmers (such as my Needhams) have a cover that closes over the chip to program it, so a removal knob might interfere with closing the cover. Maybe the programmer will make contact anyway with the cover open, haven't tried it so I don't know.
