What's wrong with detergent? If you're worried about scents, use a nonscented one. If you're worried about surfactants, use something that's based on carbonate, such as oxyclean, or straight soda beads, followed by an acid rinse. The procedure for cleaning anything dairy is the same for all equipment. First, something caustic to break up the fat and protein. Then, something acidic, or plain water rinse, to neutralize the basic detergent and make the surface suitable for use.
