A Ses is a tray of traditional Zoroastrian items having symbolic importance, and used during various ceremonies and occasions. Most are made of silver or stainless steel, and is usually cleaned during Nowruz and the Parsi New Year. A pure silver Ses can tarnish easily, so here is my very easy and quick way to clean your items. This is great to do before lacquering, but will only work on a pure silver, uncoated Ses. This method of cleaning also works well with pure silver cutlery and jewellery.
