What you are looking at
The most visible change after a plant wash is not brighter color but the return of the color the rug had before the soil settled into it. The second change is texture: pile that was matted stands up again after the centrifuge and grooming. The third is invisible in a photograph: the rug is two to ten pounds lighter, and it no longer smells.
Every rug that comes through the plant is photographed front and back at inspection; with your permission, some of them end up here. If you would like a before‑and‑after set of your own rug, ask when you book.
