After the weaving of a rug is completed, it is taken down from the loom and washed to remove the fragments and small pieces of wool that have remained amidst the wefts and warps of the rug after it has been clipped.

This operation gives luster and shine to the fibers of the wool, and causes the pile to take its natural smooth direction and the design, too, looks more distinct.

This washing brings additional colors out of the skeins of wool giving a pleasant shade to the rug.

Rug washing is a technical process. If not washed correctly the colors of different parts may bleed into each other. Expert craftsmen can eliminate the bleeding of colors by chemical substances, but it is best to test the fastness of the dyes, especially the red and dark blue colors before washing the rug.
