Different types of mirrors require different cleaning techniques. Gilded mirrors, for example — especially vintage pieces — may oxidize with the use of cleaning products or water, so it is best to simply and lightly dust their frame with a clean, soft cloth or brush. Most other styles have a frame that can be cleaned with a paper towel or soft, damp cloth. Glass and mirror cleaner is okay for the mirror itself, but we recommend spraying it onto the cloth first and not directly onto the mirror, as dripping chemicals stuck in the frame may cause damage over time. Be sure to dry the mirror when you are finished cleaning by wiping away any leftover moisture or cleaners.
A well-ventilated area assists in keeping the mirror dry, and we recommend hanging your mirror in an area where it can be admired without the risk of nicks, wall leaks, or other issues.
