1. Avoid bumps. Although most people think that iron is a very solid object and will not cause serious consequences due to a little collision, there is an old Chinese saying that "dripping water can penetrate stone". For water drops, stones are so hard, but they can still be hurt by themselves. It can be seen that avoiding bumps on iron gates is a very important thing.

2. Daily cleaning. Clothes will always be cleaned after wearing for a long time. Qingdao iron gates also need your careful care. In daily cleaning, we use pure cotton cloth to wipe. If we encounter a depression that is difficult to wipe, we can use a soft wool brush or a soft-bristled toothbrush to brush it, and then wipe it clean with a pure cotton towel. Do not use a hard steel ball to wipe, otherwise it will damage the paint film on the surface.

3. Avoid corrosive objects. Although the surface of the iron gate is painted with a layer of paint, its anti-corrosion is not as strong as we think. Therefore, we must not let some corrosive objects stick to the iron gate, such as vinegar and soapy water often used at home. If it is accidentally stained, it should be rinsed immediately and wiped dry with cotton cloth.

4. Keep dry. In general, the iron gate is not afraid of water, but not afraid of water does not mean that it can be with water for a long time. If it rains and the door is wet, we must not ignore it. After the rain stops, we must wipe the rain with cotton cloth, otherwise, the iron gate will rust easily in the long run.

5. How to remove rust. After a long time, even if it is well protected, it is difficult to avoid rust on the iron gate. If the rust range is small, you can wipe it with cotton yarn dipped in motor oil, and then wipe it with a clean cotton cloth. Do not wipe it with sandpaper or steel wool. If the area is large, it is recommended that you should find a professional to maintain it.
