Description:It is better than conventional sponges. It doesn& 39;t need water so that will not reduce the tip& 39;s temperature.As long as the solder iron pen is inserted into a steel wire ball and gently rotated a few times, the remaining welding slag on the solder iron pen can be cleared.After cleaning the wire for a period of time, you can rinse the wire with water and then reuse it.Attentions:Wear gloves when replacing steel wire, and place the cleaner stand upright when opening. The wire is flexible and may spatter solder residue, so be careful.When removing the clean steel wire, it must be cooled to prevent injury.Type: CleanerMaterial: CopperFeatures: Ball Shell Design, with Stand, Cleaning ToolBall Size: 2.7cm x 2.7cm x 3cm/1.06" x 1.06" x 1.18" (Approx.)Notes:Due to the light and screen setting difference, the item& 39;s color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Included:1 x Cleaner
