Cleaning Tools
You should clean the soldering iron tip regularly to maintain performance and prolong its lifespan.
The end of the solder tip is usually mechanically processed and galvanized, so only special cleaning tools should be used. Avoid using abrasive materials like sandpaper or files. These can remove the protective plating and dramatically shorten the tip’s lifespan.
The dry cleaner made of soft metal fibers is the best invention for cleaning the iron tip. This is because it cleans effectively without causing thermal shock. Unlike water-based sponges, it doesn’t lower the tip temperature.
A cheaper option is a wet sponge, but it doesn't clean the tip very well and can cause microcracks, as the water cools the tip.
