Maintenance Tips for Your Soldering Iron

To keep your soldering iron working like new and ensure great results every time, here are a few simple maintenance tips:

• Keep the tip clean: Regularly wipe the soldering tip with a damp sponge or brass wire cleaner during use to remove oxidation and residue.
• Tin the tip: Before and after each use, apply a small amount of solder to the tip. This helps protect it from corrosion and maintains heat transfer.
• Use the right temperature: Avoid running the iron hotter than necessary—it prolongs the tip’s lifespan and protects your glass.
• Turn it off when not in use: If you’re taking a break longer than a few minutes, turn off the iron to prevent overheating and tip damage.
• Store properly: Let the iron cool completely before storing it in a safe, dry spot.

Following these simple steps will help your soldering iron last longer and keep your stained glass projects perfect every time.
