This solder tip cleaner offers an alternative to wiping with a wet sponge - as such, the temperature of the solder tip is not altered in the same way that it would be were a sponge utilized. Spare gold plated curls clean the tip, while the heavy metal bottom and rubber grip on the bottom of the unit keep it from sliding around whilst cleaning. Essential for frequent solderers.
