The provided reference does not directly address using steel wool on copper. However, based on general knowledge and the reference provided, here's a breakdown related to using abrasive materials, including steel wool, and their potential effects on copper:
Understanding Abrasives and Copper
Copper is a relatively soft metal. Using abrasive materials can scratch or damage its surface. Therefore, careful consideration should be given to the type of abrasive used.
Steel Wool on Other Metals
The reference mentions using steel wool on iron. Specifically, it states that "a light gauge steel wool works well" to scrub rust off iron handles. This indicates that steel wool can be used on metal, but the gauge (coarseness) is important.
Potential Issues with Steel Wool on Copper
- Scratching: Steel wool, especially coarser grades, can easily scratch the soft surface of copper. This can dull the finish and create an uneven appearance.
- Embedding: Tiny steel wool fragments can become embedded in the copper, leading to corrosion or discoloration over time.
- Galvanic Corrosion: When steel (iron) and copper are in contact in the presence of an electrolyte (like water), galvanic corrosion can occur. The steel will corrode preferentially, but it can still affect the appearance of the copper around the embedded steel fragments.
Safer Alternatives for Cleaning Copper
Instead of steel wool, consider these safer alternatives:
- Soft Cloths: Use soft cloths with appropriate copper cleaning solutions for general cleaning.
- Copper Polishes: Specially formulated copper polishes are designed to clean and protect the surface without scratching.
- Baking Soda Paste: A paste of baking soda and water can be a gentle abrasive for removing tarnish.
Summary
While steel wool could theoretically be used on copper in certain limited situations, such as removing heavy tarnish or corrosion, it's generally not recommended due to the high risk of scratching and potential for embedding steel fragments that can lead to future problems. Opt for gentler methods specifically designed for copper.
