TDI Brass Finish Products: General Information and Maintenance

Brass Finish Disclaimer

Brass, an alloy primarily comprised of copper (Cu) and zinc (Zn), is renowned for its outstanding mechanical properties and chemical stability. It exhibits remarkable fabricability, corrosion resistance, and inherent antibacterial properties, rendering it exceptionally versatile for a wide range of applications. However, brass is prone to tarnishing due to its susceptibility to oxidation. Oxidation is an electrochemical reaction that occurs when brass is exposed to atmospheric oxygen (O2), resulting in the formation of copper oxide (CuO) and zinc oxide (ZnO) compounds on the brass surface. This oxidation process causes the brass to darken and lose its luster shortly after manufacturing, regardless of storage or packaging conditions.

It's important to note that TDI does not provide an unconditional guarantee of tarnish or corrosion resistance for satin or polished brass finishes. However, as a proactive measure, we highly recommend the use of TDI Clear Coating during the manufacturing process. This clear coating serves as a protective barrier, assisting brass in retaining its original factory finish for an extended period. In cases where TDI Clear Coating is not applied to satin or polished brass finishes, tarnishing due to oxidation becomes inevitable. To restore brass to its optimal condition, meticulous care and maintenance procedures should be followed.

In order to offer a more resilient finish, we employ a powder coat process instead of lacquering. This process is known for its enhanced durability. However, please be advised that this option is available upon request and incurs an additional cost and longer lead time. Additionally, it’s important to note that special finished materials are non-returnable.

Care and Maintenance Recommendations

To ensure the longevity and appearance of TDI brass finish products, we provide the following care and maintenance recommendations:

Clear Coating: If you wish to prevent tarnishing and maintain the original finish of satin or polished brass, we strongly recommend specifying TDI Clear Coating during the manufacturing process. This protective coating acts as a barrier against oxidation and helps the brass retain its luster for an extended period.

Routine Cleaning: Regular cleaning is essential to remove dirt, grime, and environmental pollutants that can accumulate on the brass surface. Use a mild, non-abrasive metal polish in paste form or a solution of warm water and a gentle soap. Gently wipe the brass with a soft cloth or sponge, ensuring all areas are thoroughly cleaned. Avoid using harsh chemicals or abrasive materials that may damage the brass.

Tarnish Removal: If tarnishing occurs on brass finishes without clear coating, prompt action can restore the original shine. For mild tarnish, utilize a metal restoration polish specifically designed for brass. Apply the polish following the instructions, allowing it to dry before gently buffing the surface with a soft cloth or pad until the tarnish is eliminated. For Tarnish removal, we find acetone effective for removing fingerprints. For satin brass finishes, rebushing can also be effective in revitalizing the appearance.

Preventive Measures: Minimize direct exposure of brass finishes to harsh elements, excessive moisture, and extreme temperatures. Consider using protective covers or placing brass items in enclosed areas to reduce oxidation. Additionally, avoid contact with acidic substances, such as citrus juices or vinegar, as they can accelerate tarnishing.

Periodic Maintenance: Conduct regular inspections of the brass finish products to identify any signs of wear, corrosion, or damage. Address any issues promptly by following appropriate repair or maintenance procedures. If unsure, consult with professionals or refer to the manufacturer's recommendations.

By adhering to these care and maintenance recommendations, you can effectively preserve the appearance and ensure the optimal functionality of TDI brass finish products. This diligent approach will enhance their longevity, safeguard their beauty, and maintain their performance over time.
