Polish Cloth
Polish Cloth
A treated cloth for restoring lustre to gold, silver, and platinum jewellery
A polish cloth is a soft cloth impregnated with a fine abrasive or a chemical cleaning compound, designed to restore lustre to precious-metal jewellery between professional services. The familiar jeweller's cloth is a domestic-grade tool, recommended in care guides issued by GIA and the major retail chains, and is one of the few maintenance items that can be sent home with a customer without the risk of damage that more aggressive treatments carry.
Composition
Polish cloths are typically two-layered: an inner pad treated with rouge, tripoli, jeweller's red, or a proprietary chemical compound, and an outer wiping layer for buffing residue away. Rouge is iron oxide; tripoli is a fine siliceous abrasive; both are mild enough to remove tarnish from sterling silver and karat gold without measurable metal loss across normal use. Some cloths are formulated specifically for silver and rely on chemical reduction of silver sulphide rather than mechanical abrasion.
What it works on
Gold, silver, and platinum mountings respond well to a polish cloth. Sterling silver, the metal most prone to tarnish, sees the most regular use. Karat gold dulled by skin contact, cosmetics, or chlorinated water can be brought back to a near-original lustre with light cloth work. Platinum, slower to dull but still subject to surface scuffing, also takes a cloth polish.
The cloth is not appropriate for all surfaces. Plated jewellery — vermeil, gold-plate, rhodium-plate — should be cleaned only with the unmedicated outer layer or a dedicated plated-finish cloth, because the abrasive can wear through a thin plating. Mirror-polished surfaces, satin finishes, and intentional patinas can all be flattened or removed by a vigorous cloth polish, and the operator should consider whether the original finish should be preserved before working.
What it should not touch
Polish cloths are not for gemstones. The abrasives that remove tarnish from metal will mar the surfaces of porous, soft, or treated stones. Pearls, turquoise, opals, emerald, and any treated or oiled stone should be kept away from the cloth. The cloth should be used on the metal mounting between gemstones, with care taken to avoid touching the stones themselves.
In the trade
The jeweller's polish cloth is included in many bridal and fine-jewellery purchases as part of an after-care package. GIA's consumer care guidance recommends mild soap and warm water as the first line of cleaning, with the polish cloth reserved for restoring lustre to dulled metal. Heavy tarnish or visible wear should be addressed by a professional jeweller rather than at home.
