Steel wool is a bundle of fine steel fibers that is often used for cleaning and polishing surfaces. It is effective at removing rust, paint, and grime from various materials, including wood and metal. The texture of steel wool allows it to reach into small crevices and corners, making it a popular choice for household cleaning tasks. In addition to cleaning, steel wool can also be used in crafts and DIY projects. It can be shaped and molded for artistic purposes or used as a fire starter due to its flammable properties. However, care should be taken when handling steel wool, as it can cause scratches on delicate surfaces.
