The thermos cup is a very common cup in autumn and winter. A thermos cup can be used for several years. During long-term use, many people may find that the thermos cup becomes rusty. When faced with thermal insulation What should we do when the cup is rusty?
Will stainless steel thermos cups rust? Many people have the impression that stainless steel thermos cups will not rust. In fact, this is not the case. Stainless steel is just less likely to rust than other steel materials. A good thermos cup will not rust very easily. It is easy to rust, but if we use improper methods or do not maintain it properly, then it is understandable that the thermos cup will rust!
There are two types of rust in insulation, one is caused by human factors and the other is caused by environmental factors.
1. Human factors
High-concentration salt water, acidic substances or alkaline substances are stored inside the cup. Many friends have bought a new thermos cup and if they want to clean it thoroughly, they like to use high-concentration salt water to sterilize and disinfect it. If salt water is stored inside the cup for a long time, the stainless steel surface will be corroded, resulting in rust spots. This kind of rust stain cannot be removed by other methods. If there are too many spots and it is too serious, it is not recommended to use it again.
2. Environmental factors
Generally of good quality, 304 stainless steel water cups will not rust easily if used normally, but this does not mean that they will not rust. If the cup is stored in a hot and humid environment for a long time, it will cause the stainless steel to rust. But this kind of rust can be removed later.
The method of removing rust from the thermos cup is also very simple. It can be easily removed by using acidic substances. When the thermos cup is rusty, we can use acidic substances such as vinegar or citric acid, add a certain proportion of warm water, pour it into the thermos cup and place it. The rust of the thermos cup can be removed in a while. If we want to prevent the thermos cup from rusting, we must use and maintain the thermos cup reasonably. Once the thermos cup becomes rusty, it will have an impact on the service life of the thermos cup.
