Over time, a mirror in a bathroom or hallway may lose its crystal clarity. Even with frequent cleaning, streaks, dull spots or a general “milky” coating appear on the surface. This happens not only due to dust, but also under the influence of external factors that destroy the structure of the reflective layer.
Effect of high humidity
The main enemy of any mirror is excess humidity. If a mirror hangs in a bathroom with poor ventilation, water vapor constantly settles on the surface. Moisture penetrates microcracks and reaches the back wall, where amalgam. It is damage to this layer that causes irreversible clouding that cannot be washed off with conventional means.
Mistakes when choosing cleaning products
Often the cause of dullness is improper care. Use of powders with abrasive particles leaves micro-scratches into which dirt gets clogged. Window cleaners containing harsh chemicals can also cause harm. They can react with the coating if they get on the edge or back of the product.
Exposure to sunlight
Direct sunlight is harmful to the mirror surface. Ultraviolet light heats the glass and destroys the protective varnish covering the amalgam. Over time, the mirror fades, becomes dark, or becomes covered in spots that look like mold. The best place for a mirror is an area with diffused light.
Natural aging of materials
Any mirror has its own service life. Over time, the protective layers become thinner, and the metal coating begins to oxidize from contact with oxygen. If the cloudiness occurs from the inside and is accompanied by the appearance of black dots along the edges, this is a sign amalgam corrosionwhich can no longer be corrected at home.
Prevention and proper care
To extend the life of a mirror, it is important to ensure good air circulation indoors. It is better to wipe the surface with a soft microfiber cloth using special alkali-free products. You can protect the amalgam from moisture by treating the back surface and joints with sealant or oil-based paint.
Proper care and protection from aggressive environments will help keep the mirror clean for many years.
