A "soiled shirt" refers to a shirt that has become dirty or stained, often due to spills, sweat, or other contaminants. This condition can occur with any type of shirt, whether it's a casual t-shirt, a dress shirt, or a work uniform. The presence of dirt or stains can affect the shirt's appearance and may require cleaning to restore it to a wearable state. Cleaning a soiled shirt typically involves washing it with detergent, and sometimes using stain removers for tougher marks. Depending on the fabric, the washing method may vary, with some shirts needing special care to avoid damage. Regular maintenance can help prevent shirts from becoming soiled in the first place.
