Correct - DO NOT RINSE STAR SAN.
Remember, however, to have everything CLEAN first. Take things apart (spigots, bottle fillers, keg parts, etc.) You want the sanitizer to be able to get everywhere and you want to make sure there are not any pockets harboring anything. A key to sanitation, in my experience, is to always clean stuff right after using - don't let anything sit around. Once stuff starts to dry on, everything becomes tougher.
