Today getting a good and superior quality mirror is not an easy thing to achieve. Glass mirrors play a critical role in creating a huge impact on the kind of interiors that we choose for designing our homes or even our workplace. Once we purchase a mirror, there are a few minor aspects that we need to focus on. We normally look for cracks or chips while buying mirrors, but we also need to mull over the back (the important bits that can’t be easily seen). Moisture is the main culprit responsible for the damage caused to the mirror, which happens because the moisture reaches the front of the mirror from the back, leading to oxidization, which forms black spots on the mirror.
Oxidization mainly occurs on the mirrors when the moisture slides through into the glass and therefore causes a layer between the glass and the silvering, which gives the glass its reflective effect. Oxidization, therefore, leads to black spots on the surface of the mirror. These spots cannot be cleaned or even removed as they are not on the mirror, but they are formed within the mirror. It is always said that prevention is better than cure. This phrase is most applicable to a mirror because any damage done to a mirror is irreversible because there is no solution to it other than replacing it with a new one. If the damage is at the edge, it can be corrected by reframing the mirror, but in that case, care has to be taken to make sure that the reframing is done so that no space for moisture to re-entering is left.
Few preventive methods can be adopted to avoid such kind of damage. There are a few mirrors specially designed for bathroom usage only, so any other mirror should not be hanged in bathrooms. They are likely to get moisture damage because of the steam that gets accumulated in bathrooms.
