How can I find a good way to clean a soiled couch?
assistant
1.  Start by vacuuming the couch to remove any dirt, dust and debris that may have accumulated on it.
2.  Use a mild detergent or soapy water solution to scrub away any stubborn stains.
3.  If necessary, use a dry cleaning solvent such as rubbing alcohol to help lift out deeper stains.
4.  Rinse off the sofa with warm water and then allow it to air dry completely before returning it to its original position.
