Float-washed 3 times in slightly alkaline deionized water (pH 8.0, calcium hydroxide added) to reduce discoloration as far as possible. Exposed to filtered sunlight whilst wet to further reduce discoloration and foxing. Paper and adhesive residues removed whilst wet. 

Reattached lower corners with thin Japanese tissue and wheat starch paste. 

Humidified, then straightened under light pressure between sheets of smooth mat board and foam. 

Japanese paper hinges adhered to upper corners with wheat starch paste. Hinged into 4-ply rag mat.
