This tip cleaner eliminates the temperature variation associated with the wet sponge approach and does a better job to boot! The special "Curly Brass" insert does not need to be kept wet and cleans without damaging the tip. Uniform iron temperature ensures consistent joint quality and reduces cycle times. The heavy- duty stainless steel holder has a rubber base so it won't slip around the bench.- Measures 90 mm diameter x 40 mm high.
