🛠️ HOW IT WORKS (The Process)

  1. Clean: Ensure your steel item is free of grease and dirt.

  2. Dip: Submerge the item into the blacking solution.

  3. Blacken: Watch the chemical reaction turn the steel black in minutes.

  4. Protect: Once removed, treat the item with dewatering oil, varnish, or lacquer.

⚠️ IMPORTANT TECHNICAL INFO:

  • Zinc Plated Items: This process will work on Zinc plated items, but NOT on Yellow Passivated Zinc.

  • Rust Protection: The black layer produced offers very little protection against atmospheric attack on its own. You MUST treat the item after dipping with Dewatering Oil, Varnish, Lacquer, or another barrier to prevent rusting.

  • NOT SUITABLE FOR STAINLESS STEEL
