I went and dug up my thread on buying my first suppressor, and I posted that I got The Call in February 2019. I'm probably getting close to 1k rounds through it, so I figure it's time to clean it. I read in the owner's manual that there's a "dip" of hydrogen peroxide and vinegar, but some old threads around here made it sound like this mixture is highly toxic. I'm no scientist, and I really don't want to start creating biohazardous liquids in my home. Nor do I have any idea where I would dispose of such hazardous waste. Is there a less toxic, but (close to) equally effective dip? I'm not adverse to investing in one of the less-expensive ultrasonic cleaners if that's really the way to go. As an aside, I went to a gun show this weekend, and a new .22 was high on The List of things I wanted to look for. I've discovered that a threaded barrel is a big factor in picking a new .22 now. I'll assume that's normal.
