Unless you live in a sauna, poolside cabana, gymnasium, or house of ill repute, the kitchen and bathroom are likely the most moist and oily rooms in your home. Over time, a thin film develops on glass shades.Fortunately, a soak in warm, soapy water cleans opal glass shades (it's also easier to remove latex paint drips). For stubborn scuffs, gently-applied four aught (0000) steel wool removes imperfections.Afterwards, clean your fixture by following the guidelines at the bottom of our Lighting Finishes page.
