A: No, it only reacts with copper-based metals. the solution works beautifully on solid or raw unlacquered brass, copper, bronze, and sheet tin; nor, on stainless steel, aluminum, iron, chrome, or zinc unless they have been heavily plated with copper or brass,

Q: Do I need to strip the metal before applying the solution?

A: Yes, the metal surface must be completely bare. Many modern brass items are coated in a clear factory lacquer or oil protectant to stop natural tarnishing. You must remove this clear coat first using paint stripper, acetone, or light steel wool so the solution can chemically bond with the metal.

Q: Is the antique darkening effect permanent?

A: Yes, the solution changes the actual surface finish of the metal. It is not a paint or a dye that will chip or peel away over time. However, because it creates a true living patina, high-touch areas will naturally buff out or lighten beautifully over years of handling. You can lock in your exact shade permanently by applying a clear wax or lacquer seal after drying.

Q: How long does the darkening chemical reaction take?

A: The reaction happens almost instantly. It begins changing color within 10 to 30 seconds of application. The gradual process gives you complete control over your shade. You simply rinse the piece under cold running tap water the exact second you hit your desired level of aging to completely freeze the reaction.

Q: Does this solution damage or eat away at the metal details?

A: No, it causes zero dimensional or structural changes. Brassager is engineered to oxidize the surface molecules safely without etching, pitting, or eating away fine engravings, threads, or delicate architectural details.

Q: Can brass ager solution be reused ?

A: Save the liquid: Pour the used solution back into its plastic container using a funnel.

Filter out debris: Strain the liquid through a coffee filter if it contains dirt or metal particles.

Store safely: Keep the bottle tightly sealed in a cool, dark place.

Check the strength: Discard the solution when it stops darkening the brass; otherwise, discard it if it takes too long to work
