Copper tarnishes, will my CuVerro® surface tarnish?
Q: Copper tarnishes, will my CuVerro® surface tarnish?
A: Despite the fact that CuVerro® bactericidal copper surfaces have been formulated for their strong resistance to tarnishing, all uncoated copper alloys are subject to natural oxidation. The effect however will be more comparable to the subtle surface changes typical of copper-nickel coins (such as dimes, nickels and quarters), which over time, shows minimal color change, compared to the more noticeable tarnish that can develop with, for example, a copper penny.
While the rate that copper alloys tarnish varies widely from alloy to alloy, the CuVerro® Rose and CuVerro® White Bronze provide a clean, professional-grade appearance that is easily maintained and relatively tarnish resistant. And when healthcare facilities follow prescribed cleaning protocols for antimicrobial surfaces, tarnish concerns will be largely mitigated.
Furthermore both laboratory testing performance shows that copper alloys retain their antimicrobial efficacy through normal oxidation. Tarnish does not impair antimicrobial effectiveness.
