1No need to add water, to avoid the temperature of the soldering iron tip, no solder balls will erupt and improve the welding efficiency. 2 To prevent the iron tip from oxidizing and to increase the life of the soldering iron tip. 3 Effectively remove oxides and solder on the soldering iron while multi‑point contact cleaning effect is better, effectively provides work efficiency. 4 Replacing traditional water‑permeable sponges, suitable for EU and US RoHs standards. 5 Metal soldering iron tip cleaner uses high‑quality brass wire, does not reduce the temperature when cleaning, suitable for all kinds of welding tip, high temperature resistance with long service life. Item Type: Soldering iron tip cleaning wire Product Material: Brass steel alloy Product Use: Widely used for cleaning iron tip Instructions: 1. Insert the tip of the soldering iron into the wire in the tip washer to remove the residual solder from the tip of the soldering iron. 2. Do not use the wire in the tip washer as a sponge to sweep the tip of the soldering iron, because the wire is like a spring, and it may spill the residual solder on the tip of the soldering iron. Please use it carefully. 3. When replacing the metal wire in the tip washer, please wear gloves, be careful not to spill the solder, and open the box upright. 10 x Soldering Iron Tip Cleaning Wire
