How to Care for Pewter Inlay and Furniture Mounts

Pewter is a family of tin-based alloys used in inlay and mounts. It is softer than brass, scratches easily and may corrode in contact with moisture or incompatible materials.

Why the material is vulnerable

Metal and wood expand differently. Inlay can lift as adhesive fails; polishing can round engraving and contaminate surrounding veneer.

What to inspect

• Look for raised edges and loose sections.
• Identify white or grey corrosion products.
• Inspect engraving and plated surfaces.
• Check contact with brass or iron.
• Record replacement pieces and pins.

Photograph condition and identify every material before cleaning. Check hidden and protected areas; damage often begins at edges, fixings and interfaces between unlike materials.

Safe care

Handle with gloves where appropriate and dust only if stable. Keep conditions moderate. Lifting metal and corrosion require a conservator familiar with furniture and metals.

Start with environmental correction and the least interventive method. Use clean barriers, soft tools and controlled suction only where the surface is stable. Stop if colour, flakes, fibres or corrosion products move.

Avoid

• Metal polish in situ.
• Steel wool or abrasive pads.
• Hammering lifted strip flat.
• Oiling corrosion.
• Flooding gaps with adhesive.

Monitoring and specialist help

Check high-touch edges and interfaces seasonally. Prevent contact with damp cleaning cloths.

Seek a conservator for active flaking, mould, structural failure, rare materials, protected wildlife products or uncertain earlier treatments.
