Spindle grub screw fixing should also be checked and tightened. Badly fitting and maintained furniture can prevent the lock from operating correctly and affect the performance of the door.Pull handles: these should be checked to ensure that the bolt through fixings or screw fixings are tight, as loose pull handles can result in damage to the door face.Care of finishesThe build up of dirt and dust on door furniture can cause a breakdown of the high quality finish. This is more likely to occur in coastal or industrial areas, and to prevent it the furniture should be cleaned as per the following instructions.Polished silver anodised aluminiumAnodised aluminium should be dusted regularly with a soft cloth and periodically washed with warm soapy water.Stainless steelGrade 316 stainless steel offers a greater resistance to corrosion. Both polished and satin finishes should be washed periodically with warm soapy water and dusted regularly.Lacquered brassWash periodically with warm soapy water and clean regularly using a wax polish. Never use abrasive or metal polish. The lacquer may eventually break down, in which case it should be removed and the furniture treated as unlacquered.Unlacquered brassThis finish should be polished weekly with a proprietary metal cleaner to maintain its polished appearance, or alternatively left to gain a natural patina.Simulated stainless steel or brassThese plated finishes should be washed with warm soapy water using a soft cloth.Silver enamelledThis finish should be cleaned with a soft cloth.Plated finishesThese will benefit from the occasional use of chrome cleaner, followed by a wipe from a cloth impregnated with a light oil.RBMA and rustic bronzeThese will benefit from the occasional wipe from a cloth impregnated with a light oil.Unlacquered bronzeThis finish should be polished regularly with a good quality metal polish, or alternatively left to allow the surface to age naturally through oxidisation.
