Stainless Steel Blackener 370 is an acidic liquid concentrate used full strength or diluted with up to 3 parts water to blacken stainless steel at room temperature. Recommended for color coding parts and blackening engravings on stainless steels. Produces a pleasing dark gray/black finish. No sealer required.






Please note, ALL stainless steel surfaces are passive by nature and will require activating. This is done by immersing in a solution of Hydrochlric Acid, available at nearly all hardware stores.
Hydrochloric acid is the acid used by brickies to clean of excess mortar.
