I think that email may be a bit alarmist, and speaks of extremes only. I use Simple Green almost EXCLUSIVELY for cleaning bike frames and parts, a great multitude of which are made of aluminum. The exception is using an adhesive remover for tough adhesive residues, and brass brushes of various shapes, for removal of rust from chrome, or black or raw steel. For my little scrubbing tub, I use Simple Green cut 50% with tap water. Where you can have a problem, is if you leave the aluminum parts in the solution for more than say an hour or so, depending upon differences in the specific parts, like manufacturer, content, and type of anodizing used, or lack thereof. Left too long, it can begin to remove and blacken anodizing, and it can begin to blacken raw aluminum as well. Simple Green is excellent for making the parts shiny clean, and cutting through grease and grime. Now that being said, if you have to leave aluminum parts in the ultrasonic cleaner for longer than this, then I'd agree that you might need to find something else, like John Barron suggested.
