I think all of us have different ways - keep in mind that most of us doing multiple batches in a day are selling. I multiples of mixing containers, spatulas, small containers for separate colors, and molds. Usually the only thing I need to clean on soap binge is my stick blender. Depending on batch size and the recipe, if it is a recipe that plays well and both soaps are simple, I will mix up the full batter that I need for however many batches I'm making, mix that up to emulsion, separate the weight for each batch, then it's simple enough to add scent, color and pour in the mold. I only do this with my super simple soaps that have a good recipe that I only want to pour a small batch for.
Last night my soap dungeon was finally put together so I could work in it. So daughter came and helped me make a foaming sugar scrub and a custom emulsified sugar scrub.
