Best way to clean out very tiny holes (threaded)?

Now that's a good possibility and brake and carb cleaners have a mixture of different 'ones' and 'enes' in them that could do the same.

Carb cleaner will. Brake cleaner usually is easier on paint and plastic. I use it carefully for getting greasy fingerprints out of car interiors.

BK is usually xylene, toluene, MEK and other solvents. Carb cleaner usually has acetone in it and it doesn't dry as cleanly without residue like BK. BK is pretty similar to paint prep solvent.

MEK is my most favorite solvent but it must be used in a well ventilated area or outdoors, preferably on a windy day. It's probably outlawed in Kalifornia.

We had 5 gallon metal cans of xylene and MEK in the garage that Dad would bring home.

I cleaned the valve body on my 442's TH400 with MEK. Then I rinsed it with hot water in the shop sink in the back room of the Exxon station I worked at.

I inhaled the steam cloud and I thought I was going to die. That shit is nasty!

Seem to always have some mineral spirits around. Have used it in the past for thread cleaning and found it to work well.
