很多老客户都在反馈，铜门上都会出现锈斑，这种情况是属于正常情况。下面由山东铜门有限公司给大家讲解一下怎么去掉铜门上面的锈斑

Many old customers are feedback, copper doors will appear rust, this is a normal situation. Next, Shandong Royal copper door Co., Ltd. will explain how to remove the rust on the copper door

醋泡法：将生锈的铜洗净，置于一小碟中，倒入少许食用醋，直至浸没。过24小时后取出，用小刷子刷去残锈，再用清水洗醋液，擦净阴干即可。

Vinegar bubble method: wash the rusty copper, put it in a small dish, pour in a little vinegar until immersed. Take it out after 24 hours, brush the residual rust with a small brush, then wash the vinegar with clean water, wipe it clean and dry in the shade.

开水浸泡法：生锈的铜有时覆盖一层洗不掉的土锈，这时可先将生锈的铜放入碗中，然后倒入温度为80℃至90℃的开水，直至被浸没。5分钟后将其取出，用小刷子刷清，阴干即可。遇到土锈严重的，还可将水加温至沸腾，使土锈脱落。

Soaking in boiling water: sometimes the rusty copper is covered with a layer of soil rust that can not be washed off. At this time, the rusty copper can be put into a bowl, and then the boiling water with the temperature of 80 ℃ to 90 ℃ can be poured in until it is immersed. Take it out after 5 minutes, clean it with a small brush and dry it in the shade. In case of serious soil rust, the water can be heated to boiling to make the soil rust fall off.

干刷法：遇铜锈或铁锈附着比较浅时，应尽量避免用醋泡等化学手段，而可改用干刷的方法。具体方法是选大号油画笔一枝，将笔头上的棕毛剪至离根部0。5-0。7厘米即可使用。先将待刷生锈的铜置于玻璃板上，固定住，握住油画笔根部均匀地刷，要注意用力，否则效果不佳，然后再用清水洗净。

Dry brush method: in case of copper rust or iron rust adhesion is relatively shallow, should try to avoid using vinegar bubble and other chemical means, and can use dry brush method. The specific method is to choose a large oil painting pen, and cut the brown hair on the head of the pen to 0. 5-0。 7 cm. First, put the rusty copper on the glass plate, fix it, hold the root of the oil brush, brush evenly, pay attention to the force, otherwise the effect is not good, and then wash it with clean water.

加热法：这种方法主要是针对锈蚀较浅的铁钱。铁锈的主要成分是氧化亚铁，其分子结构比较疏松，因此利用热胀冷缩的原理即可使部分铁钱的锈蚀脱落。但运用这一方法时，必须注意加一个承接器皿(如锅等金属容器)，此外加一些清水。

Heating method: this method is mainly aimed at the iron coins with shallow corrosion. The main component of iron rust is ferrous oxide, and its molecular structure is relatively loose. Therefore, using the principle of thermal expansion and cold contraction can make part of the rust fall off. But when using this method, we must pay attention to add a receiving vessel (such as a pot and other metal containers), in addition to adding some water.

其次是加热时间不宜过长，一般旺火加热三四分钟后，取出用冷湿毛巾捂住，锈便会自然脱落。选择加热法除锈，对象应是铁质尚好且锈蚀比较浅的铁钱，绝对不能把锈蚀严重且铜体已非常脆弱的铜钱用加热法除锈，否则本已十分脆弱的铜体会耐不住高温而支离破碎，粉身碎骨。

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. The rust will fall off naturally. The object of rust removal by heating method should be the iron coin with good iron quality and shallow corrosion. The copper coin with serious corrosion and very fragile copper body must not be removed by heating method, otherwise the already fragile copper will not be able to withstand high temperature and will be broken to pieces.
