| 1 | Surface deposits such as dirt and dust are the main cause of corrosion in metal door furniture particularly when combined with moisture in a damp atmosphere. In hardwearing environmental conditions near the coast or industrial areas acidic or alkaline deposits may build up and attack the surface finish. | 5 minutes |
| 2 | It is very important that care is taken to maintain door furniture finishes since many finishes especially anodized, electro-plated, polished and lacquered surfaces are damaged by incorrect cleaning. | 1 minutes |
| 3 | Frequent dusting using 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. | 1 minutes |
| 4 | 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 solvents, metal polishes, or cleaners containing abrasive powders or abrasive cloths and pads should not be used for cleaning lacquered or electro-plated finishes. | 1 minutes |
| 5 | Door furniture with nickel and chrome finishes should be dusted regularly. They should be washed periodically with weak detergent solutions and rubbed occasionally with a cloth dampened in paraffin or light oil. | 1 minutes |
| 6 | The doors are normally provided in a powder coat finish, 2 pack paint finish or stainless steel. These can be cleaned as follows: a) General dirt: the door can be washed down with a proprietary non-abrasive cleaning solution such as washing detergent diluted in hot water. The cloth should be wrung out so as not to soak the door or any furniture fitted to it. b) Specific dirt or problems: This will depend upon the specific item on the door and no general information can be given in this document, specialist advice should be sort. c) Damage to powder coat surface or painted surface: over time, the finish may become scratched or dented. This can be touched up with proprietary paint system. | 1 minutes |
