I have purchased from H F an ultrasonic 2 1/2 liter cleaner. I want to take good care of it and not use a cleaning solution that would not be appropiate. I have no experience with this method but several FB posts seem to think it does a good job cleaning small parts. I know many use a solution of water and simple green, but what else would be ok to use. Like perhaps Super Clean cleaner/degreaser, or Evapo Rust, ammonia? How about a weak acid or base solution?

Thank you for any suggestions.
