It is the most common type of <a href="/facts/Wire_wool/bb1r4qCG">wire wool</a> and is often the type meant when wire wool is mentioned. It was described as a new product in 1896. It is used as an <a href="/facts/Abrasive/UJ9TvVMx">abrasive</a> in finishing and repair work for <a href="/facts/Polishing/SqMg0yh9">polishing</a> wood or metal objects, cleaning household cookware, cleaning windows, and sanding surfaces. </p><p>Steel wool is made from low-carbon steel in a process similar to <a href="/facts/Broach_(metalworking)/aX9tm6eU">broaching</a>, where a heavy <a href="/facts/Steel_wire/bb1r4qCG">steel wire</a> is pulled through a toothed die that removes thin, sharp, wire shavings. </p>
