Human: How do I clean a suede couch? Assistant: 
To clean a suede couch, you should vacuum it first to remove any dirt and debris. Then use a damp cloth or sponge to gently wipe away any dust or dirt from the surface of the couch. If necessary, use a mild detergent mixed with water and a soft-bristled brush to scrub away stubborn stains. Finally, dry the couch with a clean, dry cloth and let it air dry completely before using again.
