The document summarizes the process of dry cleaning, which involves placing clothing into an agitation machine with a cleaning solution instead of water to remove stains and odors. It can take 72-86 hours to complete the full dry cleaning process, including pre-treating stains, running the garments through the machine, inspecting for remaining stains, and final pressing. The document also provides examples of fabric types that require dry cleaning rather than washing, such as silk, linen, wool, and leather.
