Has anyone used an ultrasonic cleaner for pistols and other gun parts. I just bought one at HF with the intention of filling it with Hoppe's #9 and dropping in some bolts and pistol slides that could use a good cleaning. Once I took it out of the box, though, it had a warning on the front of it that says not to use any "volitile fluids" in it.
Is there a good reason for this, or is it another example of lawyerproofing?
