Oh yes, that is exactly what it is, the fellow doing my carbs ran all the parts thru an ultrasonic cleaner afterwards for some time to make sure everything was clear. He says on the " less " intricate parts he sometimes will depending on what they are . I always wash everything that I glass bead with hot water and Dawn dishsoap and then blow it out with air. I have a couple of those scrub brushes for doing dishes that work great. Using hot water ( as hot as you can handle ) allows everything to dry out quicker. The hot water evaporates faster. Then it is all ready for painting, powder coating, ceramic coating or just nothing
