Hakko 599B-02 Solder Tip Cleaning Wire Sponge with Holder

Solder tip cleaning wire sponge with holder. Cleans soldering tips better than conventional sponges, and without the need for water. Cleaning “wire” is made from hundreds of feet of spring-wound, 1/64″-wide copper/zinc ribbon which has been impregnated with non-activated, white rosin flux. These sponges are hard enough to remove debris and some corrosion from the solder tips while being soft enough not to damage the tip. They help to remove oxides and excess solder to preserve tip life and enable clean, precise soldering.
