Also known as wire wool, steel wool, or wire sponges, these cleaning wools are more abrasive than standard welding sponges and are ideal for scrubbing off caked-on solder or residue from soldering iron tips. They don't have to be dampened to use them. Cleaning tips regularly can help prolong their life and ensure they deliver all their heat during soldering.
Replace the existing wool sponge in your storage tray with a new one to help ensure quality cleaning every time. If you don't have a storage tray, you can hold these sponges in your hand to clean soldering iron tips.
With Storage Tray
The included storage tray holds the wool sponge during use and helps keep your work area tidy by catching any solder and debris that are removed from the soldering iron tips during cleaning.
