Based on the provided information, a steam cleaner can be used to clean a couch. This method is presented as a "great option" for the periodic and proper cleaning of upholstered furniture. One key advantage highlighted is that steam cleaning is considered to be a very gentle process on the fabric, which helps in maintaining the furniture's appearance over the long term.
It is important to note, however, that the outcome of steam cleaning is not always straightforward. One of the sources alludes to an instance where an attempt to steam clean a couch did not yield the desired results. This suggests that while the method is effective in principle, factors such as user technique, fabric type, and the specific nature of the dirt or stain can influence the final outcome. Therefore, while steam cleaning is a valid approach, its success may depend on correct application and the specific circumstances of the furniture being cleaned.
