This is a very very specific question, but maybe someone on here knows someone who knows someone: Is there a dry cleaning service experienced with vintage Japanese kimono silk in Vienna?#followerpower #vienna #wien

@trav_tan
I googled for you, I don't live in Vienna, but I found some dry cleaning services in Vienna.
(search words I used:
trockenreinigung seide in wien?)
I did not look up the price, but they have phone numbers to call.

She advertises, that the United Stages Wien (4 theatres and opera houses) are her customers, to clean the antique costumes:
