This is a brass sponge that includes a sturdy base and a soldering iron holder. The sponge will help clean your soldering iron tip. Brass sponges clean better than conventional sponges and will not damage your iron tip. Made of low abrasive brass shavings and requires no water. We also sell replacement sponges below.

I've soldered for many years, and used an ordinary damp sponge to wipe the tip. That works, but I have to go wet the sponge, and either find something to put the sponge on, it the water soaks into my (particle board) workbench. This is a real improvement. It's always ready to go, doesn't drip water, cleans my iron with a quick stab (don't have to go back and wipe both sides or anything), and it even looks cool.
