平常要注意防御一些外界的有害化学物质，例如：酸类、氯化物等，还有就是在移动铜大缸的时候一定要戴棉手套，不可让手直接接触铜大缸，防止手上的汗液腐蚀。

In general, we should pay attention to the defense of some harmful chemicals from the outside, such as acids, chlorides, etc. and we must wear cotton gloves when moving the copper cylinder. Do not let your hands directly contact the copper cylinder to prevent the sweat corrosion on your hands.

在对铜缸进行清洁的时候要切忌小心谨慎，一定要用干净而又柔软的布片来擦去尘埃，对于铸铜大缸有些沟处不易用布擦到的地方最好用毛刷或是吸尘器来吹走灰尘。

When cleaning the copper cylinder, do not be careful. Clean and soft cloth must be used to wipe off the dust. For the places where the groove of the copper cylinder is not easy to be wiped by cloth, it is better to use a brush or a vacuum cleaner to blow away the dust.
