Internal hardware, including handles, letter plates and door knockers etc, should be
polished weekly with furniture polish as part of normal household cleaning.
It is recommended that external ironmongery should be cleaned every three months, or every month in coastal or industrial areas.
Dirt, dust and any surface build up should be gently wiped clean using a soft damp cloth and warm mild soapy water only. Afterwards rinse the surface with warm clean water and dry with a soft clean cloth.
All ironmongery products are coated with a protective lacquer which can be damaged by key chains and jewellery.
Chemicals, brass cleaner, wire wool and wire brushes etc. are not to be used under any circumstances as they will damage this coating.
