A scouring pad or scourer is a small pad of metal or plastic mesh used for
scouring a surface. Some scouring pads have one side made of a soft sponge-like material and the other is the aforementioned mesh.
History
The scouring pad has been reincarnated in several forms over the years. In 1928, R. B. Kingman patented the scouring ball, which was one of the first scouring pads made of a metal mesh.

material was patented by Hans J. Hartmann. This enabled the scouring pad to float. To achieve this, he used a technique to thread the metal mesh through the sponge and wrap it around the outside. This was meant to stop the scouring pad from dropping to the bottom of the sink.
In 1973, the plastic needle surface (now more commonly used) was invented by Edward Mednick, who invented the new surface as a way of reducing the damage scouring pads did to non-stick surfaces. This technology and varieties thereon are what most scouring pads sold today are based upon.
