A pipe cleaner or chenille stem is a type of brush originally intended for removing moisture and residue from smoking pipes. They can also be used for any application that calls for cleaning out small bores or tight places. Special pipe cleaners are manufactured specifically for cleaning out medical apparatus and for engineering applications. Outside of their originally intended purpose, they are commonly used in crafts, and are also popular for winding around bottle necks to catch drips, bundling things together, as a twist tie, colour-coding, and as a makeshift brush for applying paints, oils, solvents, greases, and similar substances. Description Smoking pipe cleaners normally use some absorbent material, usually cotton or sometimes viscose. Bristles of stiffer material, normally monofilament nylon or polypropylene are sometimes added to better scrub out what is being cleaned. Microfilament polyester is used in some technical pipe cleaners because polyester wicks liquid away rather than absorbing it as cotton does. Some smoking pipe cleaners are made conical or tapered so that one end is thick and one end thin. The thin end is for cleaning the small bore of the pipe stem and then the thick end for the bowl or the wider part of the stem. When used for cleaning purposes, pipe cleaners are normally discarded after one or two uses. History Pipe cleaners were invented by John Harry Stedman and Charles Angel in Rochester, New York in the early 1900s, later to be sold on to BJ Long Company, with a possibly parallel invention by Johan Petter Johansson 1923. Crafts Pipe cleaners are commonly used in arts and crafts projects. "Craft" pipe cleaners are usually made with polyester or nylon pile and are often longer and thicker than the "cleaning" type, and available in many different colors. Craft pipe cleaners are not very useful for cleaning purposes, because the polyester does not absorb liquids, and the thicker versions may not even fit down the stem of a normal pipe or into the usual hard-to-access area of applications that call for cleaning small bores or tight places. In Japan, crafting with pipe cleaners is known as Mogol art. Its name derived from the Portuguese word Mughal for a style of weaving. Workshops in malls and schools in Japan have been led by Atushi Kitanaka on an effort to support the pipe cleaner industry. Ikuyo Fujita (藤田育代 Fujita Ikuyo) is a Japanese artist who works
