I have not worked my way through all the tips - but this is one I learned back in the 80's, replacing ICs that were soldered in place. If somebody has already presented it, my apologies.
Unsolder and remove caps using your preferred method - carefully, of course.
Get a few round toothpicks. Take one, dip the end in water, just so it is not totally dry.
It helps to have steady hands and good eye coordination, and occasionally an assistant when handling the iron around critical, sensitive parts.
Use the soldering iron to heat a component hole, from the non-component side. Have the tip of the toothpick in position and force it into the hole from the component side. You should be able to feel when that happens, and it will push against the soldering iron tip. 'Spin' or twist the toothpick a bit to help it go all the way in. Sometimes the unsoldering leaves a bulge of solder and you need to preheat before you can properly position the toothpick.
Remove iron, remove toothpick. Result should be a clean hole, ready for the new component
