9 Maintenance - Cleaning Your windows and portal doors have high-grade SIEGENIA fittings. To ensure that they remain in good working condition we recommend that you inspect and maintain your windows/doors as described below at regular intervals (at least once a year or more often for school and hotel buildings). Cleaning and preserving surfaces • When treating surfaces (painting or glazing your windows/doors), remove all fittings and protect them from stains and spills. • Remove any stains or spills immediately because they could damage the surface protection of the fittings. • Use only mild, pH-neutral, diluted cleaning agents. Never use sharp objects, abrasive agents or aggressive cleaning agents (such as vinegar or acidic cleaning agents) as they could damage the corrosion protection of the fittings. • When cleaning, ensure that no water runs into the fittings. • Dry the fittings thoroughly after cleaning and oil the surface with a non-acidic and non-resinous oil by wiping them with a cloth soaked in oil. ATTENTION: After the Titan AF-X hardware surface has dried, it must not be wiped with oil. Oxygen from the air has to make contact directly with the surface to maintain self-forming passive layer of the hardware. This process would be hampered by an oil film. If you have any questions regarding your installed hardware please contact your window and/or door distributor.
