How to Care for an Antique Leather-Top Desk

Leather writing surfaces combine vulnerable skin, colour, tooling, gilding, adhesive and a moving wooden substrate. Routine furniture products can stain the leather or loosen its attachment, so care should be preventive and restrained.

Assess the leather

Look for lifting edges, tears, powdery red decay, flaking colour, brittle areas, tide marks and mould-like deposits. Do not press cracked leather to test flexibility.

If the surface is powdery, sticky, actively flaking or historically important, avoid cleaning and consult a leather conservator.

Control light and heat

Keep the desk away from direct sun, radiators, fires and hot lamps. Light damage is cumulative, while dry conditions can embrittle leather. The [Canadian Conservation Institute's leather guidance](https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/care-alum-vegetable-mineral-leather.html) recommends protection from environmental extremes and fluctuations.

Prevent abrasion

Use a clean, smooth writing mat that does not contain unstable plasticisers or rough backing. Lift objects rather than sliding them. Avoid adhesive tape, rubber feet that may stain, and heavy items left in one position for long periods.

Dust cautiously

For stable leather, use a soft brush while holding a low-suction vacuum nearby with a protective screen over the nozzle. Do not let the nozzle touch the surface. Stop if colour, flakes or powder move.

Avoid dressings and household cleaners

Leather food, saddle soap, oils, wax, cream, furniture polish and wet wipes can darken, soften, stain or leave residues. Historic leather does not automatically benefit from feeding. Water can damage alum-tawed and decorated surfaces.

Protect from spills

Keep drinks, plants and liquid ink away. If a spill occurs, blot without rubbing and seek advice. Do not use heat to dry the area.

Treat the wood separately

Products suitable for the wooden frame may harm leather. Never spray polish. If the wood needs attention, shield the leather and use a method appropriate to the identified finish.

Monitor change

Photograph the desk annually in similar light. Record lifting, fading, cracking and powder. Stable placement and limited handling usually do more good than repeated product application.
