I just noticed that Paramo looking Dawn has what looks like hints of a Coral/Pink hue bleeding through with that black. That is bad *** !
I agree with everyone here on the clean up and go. You can't buy that patina....well, you just did !
What I do is take some hot water and mix a good amount (50% or so) of non toxic degreaser (like Simple Green) up. I then get a small pile of clean rags and start scrubbing away..you don't want the rags super wet, or too dry. Go through the rags in stages, so as you clean, the rags have less and less, to zero grease and scudge remaining. When your rags end up coming up clean, you are done. I have good luck with spraying a semigloss clear engine enamel (satin or gloss if you prefer) over the painted portions...it seals in the patina. Nice Score !!
