Indeed, once the cleaning process concludes, we would be more than happy to apply Stain Protection spray to your upholstery. We even encourage doing so, as the job of maintaining the upholstery clean will become much easier. The Scotchgard-like product will create an invisible chemical layer on the surface, which will react to new spillages and make them less likely to permanently change the fabric's colour. They will also not go in as deep as they would otherwise, and will take longer to dry. Both of these contribute to the sofa's easier care and maintenance by the client, and professional cleaners as well.
