Something that saved me a bunch of time: I switched to the pvc couplers with disposable bowls maybe a year ago now. Biggest time saver ever! If a bowl is dirty, I just dump the water that's left, pop the liner out, put a new one in, fill it up and go. I don't find it that expensive. I buy them in bulk and change them any time they even begin to get grimy or have bedding in them. I also recycle the disposable bowls which makes me feel slightly better about the waste. When I had glass pyrex bowls, it seemed to take forever to clean them (dishwasher didn't do a good enough job) and I never felt like they were clean enough.
