A staple in Japanese homes for over 100 years, traditional tawashi are made from tightly bound palm fibers and used for cleaning fruits and vegetables, plus pots and pans without damaging their surfaces. Each brush is carefully tied and finished by hand and comes with a metal drying hook. (This crafting method has remained unchanged since 1907, when Nishio Shouzaemon invented the product in Tokyo.) The bristles soften slightly when wet and can be easily rinsed off when you’re done cleaning. We appreciate the smaller size—not only is it easier to grip, but you can reach pesky nooks and crannies too. It’s tough on cooked-on food, but gentle enough to use on glass, enamel, nonstick, clay, cast-iron and carbon steel surfaces. It can also be used with just warm water to scrub natural clay cookware that generally should not be cleaned with soap (so the soap smell doesn’t get absorbed by the porous clay). We recommend using a wash basin and solid soap to create the best lather. Some discoloration of the dishwater is natural and will wash away cleanly.
