Newly purchased security doors are always affixed with various advertising stickers, which affects the appearance and is also a big problem to clean. Today I will recommend some simple and effective ways to remove these small ads!

How to remove the small advertisement on the security door

You can use a hair dryer to remove it. First, turn on the hot air and aim it at the place where the advertisement is posted, because the hot air will reduce the stickiness of the advertising paper. You can tear it off easily. If there are still glue marks on the door after cleaning, use a damp towel to remove them. You can also directly use medicinal alcohol to clean it, put a little alcohol on the area where the advertisement is posted, and then rub it a few times and it will be gone.

Tips for maintaining anti-theft security doors

1. Try to push and pull gently when opening and closing the door, because long-term violent impact will loosen the parts of the anti-theft door, thereby reducing its service life.

2. Although anti-theft doors are not very expensive, they also need to be well maintained during use, so it is best to wipe the door surface with a soft cloth frequently to keep it clean, which can also prevent corrosion from corrosive substances.

3. The metal hardware of the security door is easy to rust, causing friction when opening and closing the door. You can drop a little lubricating oil on the door hardware or directly find a professional maintenance worker.

4. Do not insert debris or inject engine oil into the keyhole of the anti-theft door lock to avoid plugging. If the lock is not flexible, you can use pencil powder and add a little lubrication to restore the normal use of the lock. .
