Rolland M had the answer to how to use sodium persulfate in a 2015 thread. "For pattern welded steel I preferably use sodium persulfate (fine etch crystal), 20 Gramm in 100 mL distilled water (~70°C ) with a pad, brush or Syringe." I hope this may help someone combing the archives one day for restoration information. Attached below is the entire thread.
