How to Care for Antique Iron and Steel

Iron and steel are highly vulnerable to moisture and salts. Tools, locks, arms, clocks and furniture fittings may combine metal with wood, leather or coatings.

Safe routine care

Keep relative humidity stable and avoid bare-hand contact on clean metal. Dust carefully and inspect crevices for orange powder.

What not to do

Do not wire-brush, oil indiscriminately or apply rust converter to an antique. Treatment must account for original bluing, paint, plating and residues.

Storage and specialist help

Isolate active rust from damp sources and consult a metals conservator for stabilisation.
