8 NC 82 STH 2018/01 Cleaning of aluminum windows 66 - INFORMATION - 006 Cleaning of aluminium windows With the respect of cleaning and maintenance rules here given, the aluminium windows will keep their own performances of air-water tightness and beauty of the surfaces. In order to keep these qualities, the exposed profiles and surfaces must be subject to regular cleaning and maintenance. The frequency of intervention depends on the building surrounding and must be higher when located near the coast or in industrial and highly polluted areas. The cleaning of aluminium profiles is very simple: it’s enough to pass them carefully with a soft sponge moistened with the proper detergent. The detergent must not be abrasive, not with a basis of ammonia, not with a basis of chlorine (ex: bleach) or alkaline or acid products. The maintenance of the vents is often combined with the glass cleaning; we deeply recommend to clean the surfaces when they are not exposed to heat sources nor to the sunrays. IMPORTANT NOTES The aluminium anodised and painted can not be in contact with damp mortar or chalk. Then, during the masonry work, we always recommend to protect the vents and frames in order to avoid any possible damaging Cleaning inside the window In order to guarantee a correct working, your window should be inspected at least once a year to check that no residue or extraneous body are in the grooves and in the slides of the frame itself. This operation prevents the eventual obstruction of the drainage holes, enabling the window to keep its performances. Cleaning of the drainage holes Clear away the dust and dirt with a vacuum cleaner and, should the drainage holes be obstructed, remove the occlusion with the help of a tool similar to a rod. DO NOT UTILIZATION - Aggressive alkaline chemical products (ex. ammonia). - Strong acids. - Hypochlorites (ex. bleach). - Oxiding products. - Nitro-acetone solvents. WHAT TO UTILIZATION Water at max 30°C temperature and specific detergent for the cleaning of the aluminium parts of doors and windows anodised or painted.
