Well, like I said, I do not use flash copper so the procedure(s) may be indeed different.
You can not apply acid copper to bare steel, you must nickel strike it first, then plate with the acid copper.
If I tried to nickel strike coat a steel part that had some nickel plating still on it and pickled it then used the degreaser, the nickel would never adhere to the existing nickel on the steel part and the steel would have more of a chance to surface rust.
Being that you are applying the flash copper onto the steel/nickel part...
don't know. Someone else will have to chime in.
Sorry for the delay in getting back to you.
