          Automatic garage doors need to be cleaned and maintained after being used for a long time, so as to prevent corrosion, rust and even distortion of garage doors. It is generally recommended to clean the garage door 3-4 times a year, which can keep the garage door healthy for a long time.
          1. Lubrication of moving parts
          Electric garage doors have springs and chains to make the door move up and down easily. In order to ensure its normal operation, it is recommended to use spray oil to lubricate key movement parts at least once a year at all springs, hinges, rollers and pivot points.
          2. Check the parts regularly
          Once a year, the garage door should be thoroughly inspected and any screws, nuts or bolts that may be loose should be tightened. This is important to keep the garage door moving correctly on the roller.
          3. Gate rail cleaning
          Wipe the garage door track with a non corrosive cleaner and carefully clean all exposed parts of the drum. Remove all excess moisture. Then use specially designed garage door lubricant or powdered graphite to keep the roller moving smoothly and effectively on the track.
          4. Painting process:
          If the metal door is used for a long time, it will inevitably rust and paint off; if the wooden door is used for a long time, the surface will start to turn black and rough. It costs a lot of money to buy a new door, so how to renovate it? The easiest way is to repaint it. You can choose a mild, sunny day to paint.
          Climate conditions will have a great impact on the quality of exterior coatings. At the same time, don't forget to thoroughly clean the garage door before painting, and start painting after it is completely dry. Apply primer before painting to ensure better effect.
