Christening gown, dry clean or handwash?

[skukuza]

I'm preparing DD1's christening gown for DD2's christening next week.

It has a brown stain on it and I'm not sure the best way to get it out. I think the gown outer is polyester but very delicate fabric.

Do I need to dry clean? Or can I handwash?

Unhelpfully there's no label with washing instructions or what the fabric is.

I’d go with the dry cleaner-they’ll be able to spot treat the mark…do you know what the mark is?

Thanks. I think it's just age. It's been stored away for about 7 years

I agree with dry cleaner they'll have the proper stuff to clean it
