Just wanted to reply to your gown preservation post. Thought it would be easier to "page" you since the original post is on the second page.
I can't take my dress out of the preservation box but it looks clean. I can only see the top of it which is on a bust to keep the shape. My dress didn't have a lot of dirt on it, just wanted it clean so it didn't yellow.
Sorry, I couldn't be more helpful but I am very satisfied with Wedclean.com's service.
