The bathroom mirror in the bathroom will have black spots after using it for a long time, which greatly affects its use. Next, I will explain to you the reasons for dark spots in bathroom mirrors and the treatment methods for dark spots in bathroom mirrors.

1. Reasons for black spots on bathroom mirrors
In fact, this situation is not uncommon. The bright bathroom mirror will be under the mist of water vapor in the bathroom for a long time, and the edge of the mirror will gradually turn black or 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 kinds of black spots. One is that in a humid environment, the protective paint and silver-plated 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 to the silver oxide by air. Silver oxide itself is a black substance, which causes the mirror to look black.
Bathroom mirrors are all cut, and the exposed edge of the mirror is easily corroded by moisture. This corrosion often starts from the edge and gradually spreads to the center, so protect the edge of the mirror. Use glass glue or edge banding to seal the edge of the mirror. In addition, when installing the mirror, it is best not to lean against the wall, leaving some gaps to help the fog and water vapor evaporate.

2. The treatment method for black spots in the bathroom mirror
1. If the black spot on the mirror is floating on the surface, it means that it is a dirty thing that has splashed on the mirror. We can scrape it off with our fingernails, or apply a little toothpaste to the black spot and wipe it with a rag. Wipe it off.
2. But there is another kind of black spot on the mirror that is not dirty. It may be formed by the oxidation reaction of the metal film behind the mirror. If the black spot is produced in this way, there is no way to remove it. Can leave it alone or change a mirror. Therefore, reasonable use and maintenance on weekdays have become very important.
3. Do not use corrosive cleaners such as strong acid and alkali to clean the mirror surface, which will easily cause corrosion to the mirror.
4. The mirror surface should be wiped with a soft dry cloth or cotton to prevent the mirror surface from being wiped.
5. Do not wipe the mirror surface directly with a damp rag, doing so may cause moisture to enter the mirror surface and affect the effect and life of the mirror.
6. 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.
When using bathroom mirrors daily, pay attention to cleaning and maintenance to prevent moisture from entering the mirror surface, which will easily turn black or appear in spots.
