We recommend wiping the jewellery with a dry microfibre cloth as required to prevent residues of sweat, perfume, cream, etc. from damaging the material. Please note: Our ewellery must be cleaned dry. In particular, never use alcoholic agents.
If this is not enough, please send us a picture of your piece of jewellery, so that we can assess the damage and coordinate a replacement. That claim can be sent to info@lizas.com.
