To prevent deposits building up and attacking the surface finish, it is very important to maintain door furniture finishes. Frequent dusting with a soft dry cloth and occasional washing with warm soapy water, followed by a light application of good quality wax polish will provide a good foundation for preserving the appearance of most finishes.
Chemical sprays, cellulose based thinners and silicone based polishes should be avoided. Ironmongery fitted externally will require greater attention due to increased exposure to atmospheric conditions.
It is strongly advised that metal polishes, abrasive cloths and pads or cleaners containing abrasive powders or solvents should not be used as they can cause damage to lacquered or electro-plated finishes.
