If you removed all the loose regolith and dust from a body like the moon or Ceres, what would they look like?

An image of Ceres just popped on on my desktop's background image rotation and I started wondering what the surface underneath would look like. Would it be pretty much the same or would there be any large-scale feature changes?

Most of these bodies are silicate bodies just like the Earth. Even though they aren't resurfaced extensively like Earth, they almost certainly underwent volcanic differentiation early in their histories. If you stripped away the dust and accumulated sediments, you'd have igneous rocks like basalts, gabbros, and granitic rocks much like the crystalline basement rocks of Earth.
