I did read that info on the post for dry cleaning vintage. I would like to add that I had this dress that accidentally fell on a dirty table and it got two long stains on it. I took it to the dry cleaner and pointed it out and asked if they could get the marks out. It came back still with the marks. I took it and used a soft wet paper towel to get it out, with gentle soap. It worked and did not harm to the piece, but every piece is different. Why not dry cleaning I don't know. I knew though that I was taking a risk by doing that but I had nothing to lose at that point and instead of washing a whole piece that has a stain or mark I will try and just work on that part with a cleaner. Sometimes it works, sometimes not.
