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.About Oxidised SilverOxidisation is the chemical treatment of silver to change the surface colour to grey and black. My jewellery is oxidised to dark black with a rich luster. Oxidisation is not a permanent surface treatment and can wear off. The oxidisation on raised patterned areas is prone to burnishing off over time, especially in the case of ring shanks. This is often a positive feature as it highlights the detail of the pattern. Items such as earrings and brooches that sit static will maintain their black finish as long as they are cared for.
