To remove dirt from intricate patterned areas use a soft brush either dry or with soapy water. Avoid hard brushes or any abrasives as they will scratch the surface and remove the patina. Avoid immersing oxidised areas in any chemical jewellery cleaning solutions as this will remove the oxidisation. To clean gold areas use a soft polishing cloth that is suitable for use with gold alloys.
