Black Max provides an attractive flat, velvety black finish on silver. By using a mild steel applicator, Black Max provides a soft grey finish on gold.
Clean silver or gold parts thoroughly by ultrasonically cleaning or electrocleaning. Rinse well.
For silver, immerse in or apply Black Max with a cloth or applicator until the desired finish is obtained (20 – 30 seconds is the norm).
For gold, use a mild steel applicator (non-stainless) such as a steel brush. Apply Black Max with several passes. Oxidation will be concentrated where the steel and gold are in contact.
Highlight raised areas with a polishing cloth or buff.
