Dear Mr, Konstantinos Chatziantoniou
I suggest to determine the kind of fiber (are these fiber silk 100% or no), and kind of dirt. then you can use enzymatic treatment to remove this dirt. because i used that before with different objects with excelant results.

Dear all,
I just came across something I have not seen previously and I need your
opinion:
Before treating I tested a silk Islamic rug (16th c, very light-weight,
extremely tight woven) for a possible solvent cleaning with IMS, acetone and
also a 0,3% of Dehyphon in deionised water. The very soft rug became extremely
rigid in these tested areas. In two days these areas became softer but never
returned to their previous state. Unfortunately the rug has been purchased in
auction and this part of its previous restoration treatment remains unknown (no
documentation record exists). It must have been treated in USA considering its
previous owner, in the 60s or 70s. After brief consultation the question of
fire protection spraying of the rug was raised.
Does anyone knows why a 100%silk rug may react on all the above solvents and
washing detergent in such an extreme way?
Many thank you for your time and help
