The item should be tested in an inconspicuous area as it may cause a visible change to the finish of some metallic items. Alternative colors may be observed due to the presence of other metal ions such as copper or iron, for example. Use with caution near some plastics as the solution's alcoholic base may soften or dull the finish of some plastics.
