I normaly us my hair dryer to de fog my mirror.I also have it right above my sink.So when i get out of the shower and the mirror is steamy i take the hair dryer and blow the fog off in a few seconds... Never tried anything else...
I got some Rain-X and applied it to my bathroom mirror last night. After this morning's shower, I still had the same level of steaming on the mirror that I had before. Is there some kind of trick to applying it that I may have missed?
