Is there an issue with leaving suppressor baffles in the ultrasonic cleaner (turned off) overnight? I have the rugged obsidian baffles and the mask baffles that I have in the cleaner and unless there is some reason to not do it, I am going to leave it in the cleaner until tomorrow night when I can finish cleaning the suppressors.

Depends on the solvent. What's in "purple power"?

No idea on the situation of the original question. Me personally I would just take them out and rinse them in water to be safe. Why not 10 seconds. But they are stainless so I can't imagine that rugged says use purple power diluted to clean them and then doesn't say but be sure you don't soak them. But why take the chance.

I wouldn’t. It has lye in it, along with a bunch of other non-detailed ingredients on the SDS with no mention of %s.

I think I've done it (with Rugged Obsidian baffles), but I did not find it to be any more effective than just running another cycle or two in the ultrasonic.

If I was doing it today I'd run them a couple times, pull them out, rinse them in water, and let them sit. You're never going to get them "clean", and if you do you will never realize any measurable benefits from it versus just running them through the machine a couple times.

I think this was just a timing issue and not an attempt to soak them. I've never found that additional cycles do squat, so for me its one and done. again SS Obsidian baffles.
