I would first plug in the start hour I came in and began to get things set up in the cleaning area. I'd have the cages pre-prepped with fresh hay, water and food before bringing the rats and dirty cages into the room. I'd change four cages at a time, transporting the rats per cage (anywhere from one to four) into the fresh ones. If there was a dead rat, I would dispose of the deceased animal properly. Once completed with the job, I clean the counters, the dirty cages, sweep the floors and take the trash out. I keep stock on supplies, and reported to supervisor.
