Pumice stone wash is a type of garment finishing technique that involves using a pumice stone to soften and distress the fabric of a garment, creating a worn, faded, or vintage look. The pumice stone is a porous, lightweight volcanic rock that is rough and abrasive on one side, and smooth and polished on the other. To use a pumice stone for garment finishing, the fabric is first dampened, and then the pumice stone is gently rubbed over the surface of the fabric in a circular motion. This process can be repeated until the desired level of fading and distressing is achieved. Pumice stone wash is often used on denim jeans and other types of casual clothing to create a distressed, vintage look.
