I am a contractor working for a client who requires that the project machinery be (matte) black for use in a darkroom environment.
As a matter of course, I spec'd black oxide finish for all steel parts, but, the client is concerned about the finish wiping off onto the users hands. I know what he means I have also seen (some) oxiding jobs that left a residue on your hands, but, i also know that this is not necessarily normal.
What i would like to find out is what to look for, what part of the process is critical in ensuring a residue free condition?
