It is best to choose semi-gloss finish in polish. It lends a soft, sophisticated sheen to the doors that looks beautiful. We generally consider an item as new till the time some shine is left in it. This factor is also taken care of by the semi-gloss finish.The process involves first rough-sanding the door, then priming it with an oil primer. Once dry, the door gets skim-coated with Swedish Putty, an oil-based high-performance spackle, which then gets sanded with a fine-grit paper (220 or finer) until the surface shines like a sheet of glass. In most cases, you can use the same gentle soap solution that you used to clean the door to clean the hardware. To clean tarnished, unlacquered hardware, make a paste using baking soda and equal amounts of lemon juice and vinegar. Rub tarnished areas, using a cloth, rinse with water and dry with a clean cloth.
