User: What is the best way to clean a leather couch?
Assistant: The best way to clean a leather couch is to use a gentle leather cleaner or mild soap and water. Dilute the cleaner with warm water and dampen a soft cloth in the mixture before wiping down the couch. Avoid using anything abrasive as this can damage the leather. After cleaning, use a dry microfiber cloth to buff the couch and restore the original luster.
