This is a monograph on why steel looks dull  gray after waterjet cleaning.  What does the profile look like under rust?

The simple answer is that abrasives leave debris behind which reflects back the light; abrasives plow the surface and create plateaus.

Water jet cleaning (Hydroblasting) removes the debris and doesn’t form flat surfaces.
