Guard your Jewerly
Please save the pieces individually. Having friction creates a pile effect and being bathed with different voltages, makes the gold particles come off and can be peeled.
Clean your Jewerly
Clean with white vinegar, since this is a weak acid that will allow the piece to be cleaned without damaging or peeling it. You can also use soap and water, but the piece must be dried very well, without sunlight or artificial light for a long time.
Keep Away From
Swimming pools or the sea because oxidation is accelerated.
