Soldering Iron Bit Tip Cleaner Steel Wool

Soldering Iron Bit Tip Cleaner:

Steel wool, also known as wire wool or wire sponge, is a bundle of very fine and flexible sharp-edged steel filaments.  It is used as an abrasive in finishing and repair work for polishing wood or metal objects, cleaning household cookware, cleaning windows, and sanding surfaces.

Steel wool is made from low-carbon steel in a process similar to broaching, where a heavy steel wire is pulled through a toothed die that removes thin, sharp, wire shavings.
