Our outdoor rugs are more resistant to water and sun than other rugs. When a rug is constantly exposed to external factors, this may affect the lifespan of the rug. If the complaint is mold, moss, stain, etc, we recommend pouring dish detergent on the mentioned areas and rubbing the area with the help of a sponge or cloth then wipe over with a clean wet cloth. It is also important to dry the rug that has been exposed to water. We recommend hanging the rug to dry both sides evenly.
