What is the recommended cleaning solution for plated metal surfaces protected by a clear lacquer?

• A. Mild soap solution
• B. Strong acid solution
• C. Solvent-based cleaner
• D. Abrasion cleaner

Answer: (A)

The recommended cleaning solution for plated metal surfaces protected by a clear lacquer is a mild soap solution. This is because mild soap is gentle enough to clean without damaging the lacquer finish that protects the underlying metal. The use of a mild detergent ensures that the surface is cleaned effectively while minimizing the risk of scratching or degrading the protective layer.

In contrast, strong acid solutions can be overly aggressive and may corrode or strip away the lacquer, compromising the protection and appearance of the surface. Solvent-based cleaners could also damage the lacquer by breaking it down or causing discoloration. Abrasion cleaners are not suitable because they can scratch the surface and wear away the lacquer finish, leading to further damage. Therefore, a mild soap solution strikes the right balance between effective cleaning and preserving the integrity of the plated metal surface.
