Re: I just can't figure this out.
I doubt the smudges are from desoltion. You are probably experiencing multiple problems. If the black is taking a long time to dye, then the coating is too thin, or the dye is not hot. Could be PH level, but usually that makes the color off too.
Are you touching the parts with bare hands?
Are you rinsing with RO or distilled water?
Are you doing the entire process all at once, or maybe letting the parts sit?
Are you rinsing really well? Between all the steps? Both dunk rinse, and spray rinse?
