I've seen this discussed a few times, but wanted to just ask my all-in-one silly stupid questions together.
I use a vibratory tumbler now which works well for little stuff, but I think the slightly larger stuff would be best done in an ultrasonic. My questions:
Are ultrasonics better for bigger stuff (brackets, etc)?
Can you put plastic items in them (eject saucers, etc)?
What solution do you put in them?
How long do they take?
I think those are my questions for now!
