Ultrasonic cleaner - what solution for rust and grease?

I was adding a bit more, had to save as I go and edit as phone is playing up, I need a new one, poor thing is getting old. So will not be able to make phone calls once 3G is turned of.
 
Ah so that's what and how you are using it for.

Give it a go.

I have 5kg tubs of the stuff but never thought to use it for that.
Might try it.

It would probably just be used up by our super hard water ;-)
 
Quick though, copper...
Bushing and the like.
I think citric would may bugger them up over the time unless it was cleaning them first.

Trial and error. Check your metals.
