How to cleverly remove rust from security doors when they are rusty

Firstly, you can use tools such as a steel brush or sandpaper to clean the rust on the door, and then use a cloth to clean the surface. After drying, brush the anti rust paint twice. After the anti rust paint dries, use sandpaper to polish it to make the surface smooth. You can use the same color of varnish. If you want to prevent rust, you must pay attention to maintenance.

How to maintain the security door

1. The door leaf should be regularly wiped with a clean and soft cloth to remove dust. It is important to keep the anti-theft door dry and avoid exposure to sunlight and rain. Plastic coated steel products must be wrapped around the door with plastic film to prevent scratches. Plastic coated steel products must not be contaminated by water or other difficult to remove dust or corrosive substances to ensure the service life of the safety door. Therefore, before the decoration is completed, do not tear off the protective film on the door or cover it with paint.
2.  All door frames and security doors are made of spray plastic material. The repair method is the same as that of spraying plastic doors. However, after installation, the gap between the doors should be maintained as much as possible to avoid expansion of the frame and wall. After installation, it must be quickly fixed with cement. If the screws have been damaged and lost, it is necessary to remove any dust accumulated on the lower lock bolt as soon as possible.
3. Doorbell management: When using the doorbell, press the button to replace the battery when the battery is low, and remove the battery when leaving home for a long time to avoid corrosion or leakage of the battery.
4. The cat's eyes should be regularly wiped with a soft cloth to prevent contamination by oil or corrosive substances, and to prevent moisture, high temperature, or direct sunlight.
5. Under normal circumstances, if it is found that the lock cylinder cannot be flexibly opened, a small amount of pencil tip can be placed into a suction tube made of Qin material, aligned with the lock cylinder, and gently blown in while maintaining lubrication. If the parts are damp and have rust stains that are not easily visible to the naked eye, using a piece of fine sand or a little pencil powder can easily solve the problem.
