Say I have an assembled PCB with a QFP package on it. This device gets damaged and I need to replace it. Getting the device off is straightforward, but now all the pads have solder blobs on them. Is there a standard way of cleaning these pads off, so the replacement device will sit flat on the pads again?

There are several ways to manually remove solder
For SMD components (and in general too) I find desoldering braid (solderwick) the best option.
