Understanding Kohler Polished Nickel: Does It Tarnish?
Kohler's polished nickel finishes are renowned for their durability and aesthetic appeal. However, many homeowners wonder if this finish is susceptible to tarnish, a common issue with other metals. This article delves into the properties of polished nickel, its resistance to tarnish, and how to maintain its shine.
What is Polished Nickel?
Polished nickel is a type of metal finish created by electroplating a thin layer of nickel onto a base metal, typically brass. The 'polished' aspect refers to the final step in the process, where the nickel is buffed to a mirror-like shine. This finish is popular due to its durability, resistance to corrosion, and warm, inviting appearance.
Why Polished Nickel Resists Tarnish
Tarnish is a result of a chemical reaction between metals and sulfur or oxygen in the air. Unlike other metals like brass or copper, polished nickel has a few key properties that make it resistant to tarnish:
- Thickness of the Nickel Layer: The electroplating process used to create polished nickel deposits a thick layer of nickel, providing a robust barrier against external elements.
- Nickel's Natural Resistance: Nickel itself is less reactive than other metals, meaning it's less likely to form a tarnish layer when exposed to air or moisture.
- Sealant: Many polished nickel products come with a clear sealant that further protects the finish from moisture and other contaminants.
Factors That Can Cause Discoloration
While polished nickel is highly resistant to tarnish, it's not entirely immune to discoloration. Here are a few factors that can cause discoloration or dulling of the finish:
- Exposure to Chemicals: Harsh chemicals like bleach, ammonia, or abrasive cleaners can break down the nickel layer or the sealant, leading to discoloration.
- Moisture and Heat: Prolonged exposure to high humidity or heat can cause the finish to lose its shine or develop water spots.
- Hard Water: The minerals in hard water can leave deposits that, over time, can dull the finish or cause discoloration.
Caring for Your Polished Nickel Finishes
To maintain the shine and beauty of your polished nickel fixtures, follow these care tips:
| Do | Don't |
|---|---|
| Use mild dish soap and warm water to clean fixtures. | Use abrasive sponges, steel wool, or harsh chemicals like bleach or ammonia. |
| Dry fixtures thoroughly after cleaning to prevent water spots. | Leave water spots or soap residue to dry on the fixture. |
| Polish the fixture occasionally with a soft cloth and a mild metal polish designed for nickel. | Use metal polishes designed for other metals, like brass or silver, as they may damage the nickel finish. |
When to Consider Professional Help
If your polished nickel fixtures have significant discoloration or damage, it may be best to consult a professional. They can assess the damage and recommend the appropriate course of action, which may involve refinishing or replacing the fixture.
In the world of metal finishes, polished nickel stands out for its durability and resistance to tarnish. By understanding its properties and providing proper care, you can ensure that your Kohler polished nickel fixtures maintain their shine and beauty for years to come.
