'''Steel wool''' is a bundle of strands of very fine soft [[steel]] filaments, used in finishing and repairing work to polish wood or metal objects, as well as for household cleaning. It is manufactured by [[Drawing (manufacturing)|drawing]] ”steel wool wire”, made from low carbon steel (low enough to be close to plain [[iron]]).
Steel wool is commonly used by woodworkers and craftsmen working with paint, lacquer and varnish. Often it is used for professional cleaning processes not only on wooden surfaces but also on marble, stone and glass, because it is softer than these materials
For household cleaning use in many countries, including the [[United States]], steel wool is sold as [[soap]]-impregnated pads under such [[trade name]]s as [[Brillo Pad]] or [[S.O.S Soap Pad|S.O.S]].
Steel wool also serves as an acceptable form of Ne'itzah (scouring) according to Orthodox [[Jewish]] laws of [[Kashrut]].
Very fine steel wool is sometimes carried for use as [[tinder]] in emergency situations; it burns even when wet, and can be ignited
by fire, a spark, or by connecting a battery to produce [[joule heating]]. See [[campfire]].
