I've done a quick search but not found much on this. A customer has brought in two nineteenth century needlepoints (one dated 1839 on the work itself). Both have been framed by an amateur at some point and stretched by nailing the canvas (honestly!) to a timber 'inner' frame. The rust from the nails has gone into the canvas but not affected the works themselves too badly so far from what I can see.
However, it looks as though neither work has ever been under glass, and consequently they are really quite mucky. I've advised the client that this type of work should not be washed, but they would really benefit from a clean - and that I'd look into it!

Are there specialists out there that anyone knows of who would tackle this type of thing? And if so, what sort of costs might we be looking at? Any help would be most welcome.
Thanks,
Adrian
