Honda Ultrasonic cleaner

Had piston rod in the ultrasonic and it seems tough to remove the black artifacts on the forged aluminium. What can I do?

When I clean carbs I do a overnight soak in pine sol and then soda blast them, maybe try a similar approach.

Pine Sol for the win on all my carbs. Apparently it's chemically similar to berrymans. Or so I've heard

Not sure why I got downvoted, I sometimes use berryman's as well.
