Rug treatment is a process of cleaning and maintaining rugs. It involves the use of shampoo, which is a seven-letter word. Shampoo is a liquid detergent used to clean carpets and rugs. It is usually applied with a brush or sponge and then rinsed off with water. The shampoo helps to remove dirt, dust, and other debris from the rug fibers. It also helps to restore the original color and texture of the rug. After shampooing, the rug should be dried thoroughly before being put back in place.
