I am not an expert on ultrasonic cleaners but there are many types and many grades of same. I purchased one from an optical supply house that was going out of business. I paid under $200.00 for the unit and later discovered it sells for almost three times that amount. I have had my handguns ultrasonically cleaned and that can loosed all sorts of parts. All ultrasonic cleaners come with a wire basket to catch parts that come loose. There is also a solution that is supposed to be used, some sort of diluted cleaning agent. I have put many things in my cleaner and some hold-up better than others...parts held together by compression or crimping do not always hold-up well. Some screwed or bolted parts can come loose. One thing to be careful of is that delicate parts connected in some devices will simply come apart. My cleaner is adjustable but the difference the adjustments create still appear to really rattle any thing you put in the basket. I would NOT put turnouts of any sort, other than gauge 1, in the cleaner, you might end up with a bunch of parts and rails/frogs. Ultrasonic does not remove any corrosion other than loose particles of same. I use mine primarily for cleaning brass in my reloading work.
