How to Care for Antique Silver Safely

Silver tarnish is a surface reaction, not proof that an object is neglected. Every polishing removes a minute amount of metal, so care should balance appearance with preservation of engraving, hallmarks, fireskin and crisp detail.

Inspect before cleaning

Check for loose handles, solder repairs, thin areas, plated surfaces, filled bases, stones, wood, ivory or other materials. A method suitable for solid undecorated silver may harm a composite object.

Handle carefully

Use clean gloves appropriate to the object, and support hollowware from the base rather than a handle or spout. Fingerprints can accelerate tarnishing and stain polished surfaces.

Prevent tarnish

Store silver in a dry, clean enclosure using conservation-appropriate tarnish-control materials. Keep it away from rubber, wool, felt, some woods, polluted air and other sulphur-emitting materials. Avoid newspaper and acidic tissue.

Do not wrap objects so tightly that projecting parts are stressed. Separate pieces to prevent scratches.

Dust before polishing

Remove loose dust with a soft brush or clean cloth. Grit dragged across silver creates scratches. Do not use abrasive pads, toothpaste, baking soda paste or repeated chemical dips.

The [Canadian Conservation Institute's metal resources](https://www.canada.ca/en/conservation-institute/services/care-objects/metals.html) distinguish routine care from specialist cleaning and include dedicated guidance for silver and tarnish removal.

Polish only when necessary

If polishing is appropriate, use the least abrasive suitable product, a small amount, light pressure and clean cloths. Work around hallmarks and engraving without filling recesses with residue. Stop when the desired appearance is achieved; a mirror shine is not automatically historically correct.

Silver plate, old Sheffield plate and thinned areas need particular caution because polishing can expose base metal.

Keep records

Photograph marks and condition. Record products and dates so future owners do not repeat treatment unnecessarily.

Seek specialist help

Consult a silver conservator or experienced silversmith for important pieces, unstable solder, damaged plating, niello, enamel, stones, archaeological surfaces or uncertain coatings. Do not attempt to remove intentional patina.
