I also went in half with a friend on this: 2.5 Liter Ultrasonic Cleaner

I'm eager to get everything setup and do some polishing! The ultrasonic cleaner is pretty cool. Nothing amazing though. Seems to just loosen things up a tad. I also suspect thats because it doesn't have the proper solution in it. Just some generic "detergent" from Harbor Freight that isn't even recommended for use with aluminum.
