Q: I recently installed a new bathroom medicine cabinet with a fog-free mirror made by Home Decorators Collection. I followed the cleaning instructions, which were to use a glass cleaner (I used Windex) and a soft cloth or paper towel. After cleaning, I noticed a three-inch-long thin streak in the centre of the mirror. I tried additional glass cleaner, but I could not remove the streak. Is it possible that I scratched the fog-free coating? How can I fix this?
A: Fog-free mirrors come in two basic types. Some have heaters or hot-water reservoirs that warm the glass to prevent condensation, the tiny water droplets that form when warm, moist air hits a cold surface.
