Ultra sonic cleaning solutions

[scooter]

My wife and kids got me a ultrasonic cleaner for Father's Day. What solutions do people use for guns etc? Is there safe stuff for aluminum,stainless and blued? My intensional wasn't to use it for brass but I believe you use a different solution for that. This seams to be a lengthy process . Do you have to rise the brass in a water baking soda mix after too? I figured I would ask before I end up removing some
blueing then ask. Just trying to gather some info from the experience ones

Here is what I use. I typically will do a full break down then only those parts that are extremely bad. Works wonders on my ar bolts! Cleaner
