599B is a solder tip cleaning wire sponge with holder

This "sponge" is hard enough to remove debris, and some corrosion, from solder tips while being soft enough not to damage them. It helps to remove oxides and excess solder, preserve tip life and enable clean, precise soldering. Note that your iron-plated soldering tips will not be scratched by the soft brass wire mesh.

• Soft brass wire mesh in a metal cup
• "Shell" design keeps the solder from splattering
• It will not reduce the tip temperature
• This is a great alternative to the conventional wet/damp sponge
• May be used as a portable tool holder and cleaner
