They LOOK like aghanistan flatweaves....appraised vals might be $350 each if approx 4 x 6....maybe from 1960s....cannot be positive without seeing these in person...nice looking and worth cleaning even if stains do not come out... For cleaning I have written a short guide:


1.Vacuum the back side of the rug with a beater bar type vacuum cleaner. This loosens dirt and sand that has penetrated the rug’s pile and is trapped near the foundation.

2.Vacuum the surface of the rug thoroughly.

3.You will need a liquid cleaner specially made for woolen fabrics, such as Woolite, a small bucket, a scrub brush with nylon bristles and warm water. Mix the cleaner with warm water to produce a sudsy combination. It is important not to soak the rug with too much water, the suds will clean a rug.

4.Scoop up a brush full of the suds with a small amount of water and begin to scrub the wool pile in the direction from bound edge to bound edge in approximately one foot strokes. Try to wash one square foot at a time.

5.After you have washed each square foot of your rug, use the suds free scrub brush to comb the pile straight in the direction you would pet a cat. Then go on to the next area to be washed until you complete your rug washing project.

6.Let the rug air dry on a flat, clean surface. You may use a fan on the rug to speed the drying time. This may take at least two days.

7.After the rug is completely dry, vacuum the rug thoroughly in the direction from bound edge to bound edge to remove any soap sediment. You should notice the highlight colors in your rug more vivid and the pile has a lustrous appearance now that the wool is free from grime.

Notes:
Silk rugs should be dry cleaned by an experienced professional
Wool weakens when wet and should be handled with care until it has dried
