I deadhead daily. I too have already deadheaded the night before. Doing that means you are deadheading blooms that still look pretty good. I only do that (as Betty said) before I'm expecting company the next morning to walk through the gardens.
Some blooms are SO big that the spent bloom can fall over others that will be trying to open and prevent them from opening. Also the darker blooms can drip and stain newly opened blooms.
Last year I found that Bar Keepers Friend works pretty good to get the stains off of your hands. Give it a try.
