Their care is simple and mostly revolves around cleaning. In this case, always use a cleaner that is free of any ammonia content. The reason is that incase they drip over the edge; they can cause some ugly de-silvering. Acidic or abrasive cleaners will also damage your mirrors. Also, avoid on using crumpled newspaper when cleaning since it can cause your mirrors to smear. Keep these things in mind and you can assure yourself that you can maintain your mirrors unmarked.
