I need to replace the mirror in my bathroom because the silver backing has worn off around the bottom. The mirror has only been up about 4 years. The same thing happened to the old one. I am not sure, but a discussion with my neighbors tells me that this is a common problem here in FL. Most of us moved here from other places (less humid) and had not had this problem before.
Would having a mirror with a frame around it offer any protection? Mine are all the plain kind, no frame. I am having the same problems with two mirrors. One came from Home Depot the other from a shop selling mirors and shower doors. Both moderate prices. Anybody have any suggestions about prolonging the life of these things?
