铜氧化了怎么办？

What should I do if copper oxidizes?

铜氧化的处理方法：

The treatment method for copper oxidation:

　　1、牙膏，往水中加牙膏后泡铜一个小时;2、醋盐，用醋和食盐来擦拭铜;3、肥皂，用温热肥皂水来洗铜;4、柠檬，把柠檬切开后直接擦拭铜的表面。

1. Toothpaste, add toothpaste to water and soak in copper for one hour; 2. Acetate, use vinegar and table salt to wipe copper; 3. Soap, wash copper with warm soapy water; 4. Lemon, cut open the lemon and wipe the surface of the copper directly.

　　2、醋盐

2. Acetate salt

　　也可以把食盐与醋混合来处理，把醋和食盐倒在铜的表面不停擦拭，直到除去铜锈，冲洗干净后再用一块干净、柔软的干布擦亮，铜的表面便能恢复光泽。

You can also mix table salt and vinegar for treatment. Pour vinegar and table salt onto the surface of copper and wipe it continuously until the copper rust is removed. After rinsing, use a clean, soft dry cloth to polish it, and the surface of copper will regain its luster.

　　3、肥皂

3. Soap

　　对于具有均匀氧化层的铜，可以用温热的肥皂水来洗净，在清洗时注意不能用力擦拭，避免损害氧化层。如果铜的氧化层均匀，但金属并未受到锈蚀，不要清洗。

For copper with a uniform oxide layer, it can be washed with warm soapy water. During cleaning, be careful not to wipe vigorously to avoid damaging the oxide layer. If the oxide layer of copper is uniform, but the metal has not been corroded, it is best not to clean it.

　　4、柠檬

4. Lemon

　　把柠檬或者青柠切成两半，用来擦拭铜表面氧化发暗的地方，直到其表面恢复光泽，冲洗干净并擦亮即可。在柠檬表面撒一点食盐，除锈的效果会更好。

Cut the lemon or lime in half and use it to wipe the oxidized and dark areas on the copper surface until the surface regains its luster. Rinse it clean and polish it. Sprinkling a little table salt on the surface of the lemon will have a better rust removal effect.
