Painting on silk

The following is posted on behalf of someone who is not on the list.

An early 20th(?) century Indian painting on silk (43cm x 58cm) has
been damaged by acid-based cardboard backing. Moisture on the
cardboard backing (most likely) caused spots (2 areas, 2mm each,
and other tiny spots) on the silk. Within the stained areas, there
are two small holes (about 1 cm, each).

Can anyone recommend ways to (a) remove discoloring caused
by the backing, and (b) ways to "mend" the small holes?
