What should you do before soldering?

Before soldering, ensure you have a clean and well-ventilated workspace to minimize exposure to fumes. Gather all necessary tools and materials, including solder, a soldering iron, and safety equipment like goggles. Clean the surfaces to be soldered with isopropyl alcohol or a suitable cleaner to remove any oxidation or contaminants. Finally, make sure to set the soldering iron to the appropriate temperature for the materials you will be working with.
