Call a local commercial dry cleaner to see if anyone there has encountered this problem. Perhaps someone already has discovered a solution to the problem. If unable to contact a dry cleaner with a solution, there is another recommendation. It is highly recommended to first test the fabric before taking the following actions on a small, inconspicuous area to prevent further damage to the clothing. Re-wash the article (with a piece of paper towel underneath to absorb the stain) using a degreasing agent such as waterless hand cleaner. Then spray with a detergent and rub the stain continuously for five minutes and rinse with hot water. Repeat if necessary.
