Prepare the upholstery for cleaning by scraping away any caked-on matter with a knife. If there is a fresh liquid stain, blot the fabric with a cloth to absorb the liquid.
Apply a small amount of dry-cleaning solvent to a cloth. Gently blot the stained area with the cloth until the stain is saturated with the solvent.
Place a clean cloth to the stain and let it sit for several minutes to absorb any excess dry-cleaning solvent.
