My daughter is going to be a bridesmaid in January. She is not a dress wearing dolly so I was thrilled to be lent a dress for her to wear. The only drawback is the state of it. M wore it to do the same job and she is a total minger. I am not sure what the stains are, probably food and drink. How can I loosen them before washing? We live in Switzerland and don't have access to many cleaning products. If it's any use, the dress is 64% polyester and 36 nylon. I did think about dry cleaning it, but, as it would cost around 30 pounds with no guarantee of stain removal, changed my mind
