The Weller Brass Wire Sponge Cleaner is a dedicated tool for maintaining soldering iron performance by removing residual solder and oxidation. Designed for use without water, this cleaner allows you to plunge the iron tip directly into the brass coils to achieve a thorough clean. This process helps prevent the buildup of rust and contaminants, which assists in extending the service life of your soldering tips. The unit is supplied with a slip-resistant silicone holder to keep the assembly stable and secure on your workbench during operation.
