Oriental rugs are good in so many regards and one regard is their restorability. A customer brought in an Indian rug two weeks ago. His dog had peed on this rug for many years and the rug was never cleaned. It was spoiled and rotten. The fibers were broken. We took care of it. First we removed the damaged area, and then we restored the foundation by warping and wefting the open space area which was about 10 x 10 inches. We rewove the part by doing a knot by knot job. We matched the color and the design. We cared and paid so much attention to follow the construction of the rug, so the knots will come close the the original knots.
You may see the photos of the rug from before and after the repair job. We still have to take care of the pet urine stains which will take a couple of days. We will have to test the stains and use some light chemicals to remove the stains without damaging the fibers of the rug. The owner of the rug has not seen the rug. I will call him later this week after we remove the stains which did not come out in the cleaning process.
