So I have decided to wear our famiily veil for my June 18th wedding...but the veil is from the 1850s and has yellowed over time - perhaps a bit too much hairspray over the years and the fact that it has never been properly preserved. Any suggestions for cleaning the veil? It has a very small lace pattern sewn into the edge of the cathedral length veil. I think it is probably all cotton, since I don't think they had polyester or nylon back then...
