What you need for removing solder from a circuit: Soldering Iron MG Super Wick To professionally remove solder from a circuit, you will need the following materials: 1. MG Chemicals Super Wick de-soldering braid 2. Soldering iron PROCEDURE Step 1 Choosing the right braid Match the bead to the braid.
