Nowadays, many consumers' pure copper doors will show some patina or copper spots more or less during long-term use. Many consumers do not know what to do when they encounter such problems. Then the following pure copper door manufacturers Let me introduce how to deal with such problems. There are two main methods.


1.Heating method. This method is mainly aimed at iron coins with relatively shallow corrosion. The main component of rust is ferrous oxide, and its molecular structure is relatively loose. Therefore, the principle of thermal expansion and contraction can be used to make part of the iron money rust off. But when using this method, you must pay attention to adding a container (such as a metal container such as a pot), and it is best to add some clean water. Secondly, the heating time should not be too long. Generally, after heating for three or four minutes, take it out and cover it with a cold wet towel, and the rust will naturally fall off. Choose heating method to remove rust, the object should be iron coins with good iron quality and relatively shallow rust. Never use heating methods to remove rust from severely rusted coins with very fragile copper bodies, otherwise the already very fragile copper bodies will not be able to withstand them. High temperature and fragmentation, torn to pieces.


2. Dry brush method. When copper rust or iron rust is relatively shallow, chemical methods such as vinegar soaking should be avoided as much as possible, and dry brushing can be used instead. The specific method is to choose a large oil paintbrush and cut the palm hair on the pen tip to 0.5-0.7 cm from the root. First put the rusty copper on the glass plate, fix it, hold the root of the oil paintbrush and brush evenly, pay attention to force, otherwise the effect will not be good, and then wash it with water.
