A piece of steel wool
'Steel wool' is a bundle of strands of very fine soft
steel filaments, used in finishing and repair work to polish wood or metal objects, and for household cleaning. It is manufactured by
drawing â€steel wool wireâ€, 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 names as
Brillo Pad or
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.
