Hometalkers help- I need to clean my newly acquired white chairs!

Depending on the severity of the stain and the type of upholstery, use an appropriate stain remover on the chocolate stain. For small stains mix one tablespoon of Dawn dish soap with two cups of cold water. For more severe stains, mix one part Dawn dish soap and two parts vinegar. The soap will remove grease. Chocolate contains a variety of fats and sugars so it is important to use a combination of methods to focus on the individual parts of the stain. Use a clean white cloth to blot the solution over the chocolate stain. Make sure the cloth is clean so as to prevent fourth staining of the upholstery. Blot the solvent until it is absorbed into the upholstery. You can also use a sponge instead of a white cloth but make sure it is clean. Repeat as needed. Continue to apply the cleaning solution and blot the stained upholstery with a clean white cloth until you can no longer remove any chocolate. Blot the upholstery until the stain disappears and is dry.

If it's really bad, and won't come out, then fabric is an awesome help.
