Maintaining the Steel Door

We have to perform maintenance processes on our steel doors and the mechanisms which work on it, within infrequent but regular intervals. These processes consist of a couple of simple articles.
Maintaining the Hinge of the Steel Door: The hinges on which the door constantly moves, are important mechanisms which support the entire weight of the steel door. Steel door hinges which operate based on the friction principle, should be lubricated at least once a year with thin machine oil, through its oil holes. Squeaking sounds may begin to come from steel door hinges which haven't been lubricated in a long time.
Maintaining the Lock of the Steel Door: It may be conducted within regular intervals, at a minimal level. Since the door and lock both stand at a horizontal position, this procedure is a little hard. You can accomplish this procedure by dipping your key into the lubricant, then inserting it into and removing it from the lock base a couple of times.
Maintaining the Furniture on the Furnished Steel Door: You can accomplish this procedure by utilizing the wood cleaning material which you use for other furniture located within your home. Do not use cleaning material which contain caustic and acid based, heavy chemicals.
