If your couch has a "dry clean only" label or has a fabric cleaning code of "S", it is best to follow the manufacturer's instructions to avoid damaging the fabric. However, if you need to clean it yourself, you can try the following steps: Vacuum the couch thoroughly to remove any loose dirt and debris. Check for any stains or spots and treat them with a specialized fabric cleaner designed for dry clean only fabrics. Always test the cleaner in an inconspicuous area first to ensure it doesn't damage the fabric. If the entire couch needs cleaning, you can try using a fabric cleaning foam or solvent designed for dry clean only fabrics. Apply the foam or solvent according to the manufacturer's instructions and use a soft-bristled brush to gently work it into the fabric. Use a clean, damp cloth to remove the foam or solvent, being careful not to saturate the fabric. Allow the couch to air dry completely before using it again. It's important to note that cleaning a dry clean only couch yourself carries some risk of damaging the fabric. If you are unsure or uncomfortable about cleaning it yourself, it is best to seek the services of a professional cleaner.
