Title: Excellent Multipurpose cleaning solution
Review: I use this stuff and my Rayn Ultrasonic Cleaning machine on everything from precious metals to amethyst and other rocks I've tumbled, parts of firearms, and even my zippo blu that was clogged with flint. Whatever chemicals are in this, they havent destroyed anything I have tried to clean yet. Tried it on quite a few things.
