There are black spots on the bathroom mirror in the home bathroom, which just reflect on the face when looking in the mirror, which greatly affects the daily use. Mirrors don’t get stains, so why would they get spots?
In fact, this kind of situation is not uncommon. The bright and beautiful bathroom mirror is under the steam of the bathroom for a long time, and the edge of the mirror will gradually turn black and even gradually spread to the center of the mirror. The reason is that the surface of the mirror is usually manufactured by electroless silver plating, using silver nitrate as the main raw material.
There are two situations for the occurrence of dark spots. One is that in a humid environment, the protective paint and silver plating layer on the back of the mirror peel off, and the mirror has no reflective layer. The second is that in a humid environment, the silver-plated layer on the surface is oxidized into silver oxide by air, and silver oxide itself is a black substance, which makes the mirror look black.
Bathroom mirrors are all cut, and the exposed edges of the mirror are easily corroded by moisture. This corrosion often spreads from the edge to the center, so the edge of the mirror should be protected. Use glass glue or edge banding to seal the edge of the mirror. In addition, it is best not to lean against the wall when installing the mirror, leaving some gaps to facilitate the evaporation of fog and water vapor.
Once the mirror turns black or has spots, there is no way to alleviate it but to replace it with a new mirror. Therefore, reasonable use and maintenance on weekdays becomes very important;
Notice!
1. Do not use strong acid and alkali and other corrosive cleaning agents to clean the mirror surface, which will easily cause corrosion to the mirror;
2. The mirror surface should be wiped with a soft dry cloth or cotton to prevent the mirror surface from being brushed;
3. Do not directly wipe the surface of the mirror with a damp rag, as doing so may cause moisture to enter the mirror, affecting the effect and life of the mirror;
4. Apply soap to the surface of the mirror and wipe it with a soft cloth, so that the water vapor will not adhere to the surface of the mirror.
