Clothing maintenance
Clothing suffers assault both from within and without. The human body sheds skin cells and body oils, and it exudes sweat, urine, and feces that may soil clothing. From the outside, sun damage, moisture, abrasion, and dirt assault garments. Fleas and lice can hide in seams. If not cleaned and refurbished, clothing becomes worn and loses its aesthetics and functionality (as when buttons fall off, seams come undone, fabrics thin or tear, and zippers fail).
Often, people wear an item of clothing until it falls apart. Some materials present problems. Cleaning leather is difficult, and bark cloth (tapa) cannot be washed without dissolving it. Owners may patch tears and rips, and brush off surface dirt, but materials such as these inevitably age.
Most clothing consists of cloth, however, and most cloth can be laundered and mended (patching, darning, but compare felt).
