This wet-soldering Soldering Iron cleaner A soldering spongeis used to clean the corrosion on the tip of the iron. A dry solder sponge does nothing but damage the tip. Every time you pull the iron from the stand, it’s a good idea to swipe the tip on the sponge just to clean it off and get a nice silver tip. This will allow you to solder much more quickly and cleanly.
