The remote will not be clean but hopefully germ free - thus the product name is a bit misleading. I can guarantee that the stuck on dried boogers will still be there when it comes out. That said they should be germ free. Having a clean remote will be more important than a germ free. For instance, linens that are dingy in color may be germ free. But who wants to dingy linens? Similar for the remote.
In my world there is clean and then there is sterile. Achieving each requires different processes. For a remote what is current process for cleaning them in the hotel industry? Do they get wiped down with a combo cleaner/sterilant? What is the process for the rest of room. Personally I would be worried about other parts of the room.
