You don't need special tools for desoldering SMD capacitors and resistors. You just need a soldering station that can be set to a high temperature of about 500°C / 900°F. This is necessary in order to add the necessary amount of heat in a short time.

Components that are connected to a ground plane, such as decoupling capacitors, are hard to desolder because the ground plane absorbs all the heat. Here we need a massive soldering tip. If this is not the case, desoldering is much easier and can be done with a small soldering tip. A temperature of 425°C / 800°F may be sufficient here.
