<human>: How can I find a good way to clean a soiled couch?
<bot>: The best way to clean a soiled couch is to first vacuum it to remove any dust or debris. Then, use a mild cleaning solution of warm water and mild detergent. Use a soft-bristled brush or cloth to scrub the upholstery in circular motions. Finally, rinse the couch with clean water and let it air dry.
