SS-599B SUNSHINE Soldering Iron Tip Cleaning Tool. This tool is designed to clean soldering iron tips without the need for water, which helps maintain tip temperature and prevents thermal shock, extending the tip's lifespan. It uses non-abrasive brass shavings to gently remove oxidation and residual solder. The dome-top design prevents tin slag from splashing during cleaning. It's a compact tool that saves space on the workbench and can often fit within soldering iron holders.
