[Bluing Advice]
If there is even a little oil, it will not dye at all. Degreasing is the most important step.
Wash thoroughly with a neutral dish soap. Rinse well with water to ensure no detergent remains.

If you prefer a glossy black finish, after degreasing, pour the undiluted liquid (you can dilute it to your preference) into a paper cup or similar container. Dip a soft brass brush into the liquid and brush the object while dyeing it.
Once dyed, do not wash with water. Let it dry overnight, then brush with a clean, soft brass brush (different from the one used for dyeing) to bring out the shine.
Even if rust appears on the surface after leaving it overnight, do not worry and brush with a brass brush. A beautiful blue base will emerge from underneath.

If you prefer a matte black finish, immerse the object in the diluted liquid and, at the stage of dyeing, lightly brush the entire surface with a toothbrush while rinsing with water to remove any soot, then let it dry overnight. After drying, do not brush with a brass brush; simply spray with oil to finish.
