No where in the initial post did the OP refer to dry cleaners and commercial laundry as unique businesses. He referred to them as unique processes, and wanted to know which one he should choose.OK - but this thread was initiated to compare "dry cleaning" to "commercial laundry", referring to them as unique businesses; you could go to the dry cleaner or go to the laundry. So, I know what a dry cleaner is - although mine makes a distinction between me asking them to dry clean a shirt and launder/press it. My question remains: what then is a commercial laundry?
He is calling the process of having his shirt washed and pressed by someone else "Commercial Laundry", which is the correct use of the term.
