Spray paint the entire fixture to create an old look. Many modern-day chandeliers are a brass or silver color. Create that charming antique color with spray paint. Depending on the look you are going for, you can use a bronze metallic or an off-white color. A bronze metallic shade will leave you with a rustic antique-looking chandelier and an off-white color will give you a shabby chic finish. Tape off any parts of the chandelier that you do not want spray painted.
Make the glass or crystals appear foggy. Antique chandeliers do not have bright, shiny and new crystals hanging from them. Use a pre-made frosting spray, found at your local craft store, to create an antique style. Alternatively, you can make your glass or crystals appear foggy or old by creating a mixture from equal parts baking soda and water and then soaking each crystal in the mixture. Do not rinse and then allow to dry and you will have that antique look you are trying to achieve.
Distress the chandelier. Many antique chandeliers are worn around the edges. You can lightly distress parts of your chandelier by using a fine-grit sandpaper to rub in certain areas, which will create a worn look. This is especially important if you are trying to achieve a shabby-chic antique finish.
