Professional washing is recommended as needed to prevent dirt buildup. Often involving total immersion of the rug into a wet bath, any cleaning should be done by a handmade rug specialist with proper cleaning practices and drying facilities.
HEMP AND LINEN
Rugs made from hemp or linen are prone to water spots and should be cleaned with dry cleaning solvents only. If water spots occur, the rug should be given a professional wet bath cleaning (fully immersed in water and dried evenly) to remove the spot.
In case of spills, blot up as much liquid as possible with a clean white cloth. Do NOT rub.
