Solder Iron Tip Cleaning SpongeThis is a high quality sponge made specifically for cleaning soldering iron tips that can quickly clean the tip surface of the oxide while causing no harm to the tip of the alloy layer. To avoid oxidation of the soldering iron head, avoid overheating, remove solder residue, and keep the PCB board clean. Use this sponge to clean your soldering iron tip to extend its life. This sponge swells up when soaked in water and can hold water for a long time.
