Tip #7 – If you have brass hardware on your windows, use a dry, clean, soft cotton cloth to remove dust and dirt from the protective lacquer coating on the hardware. Over time, all brass hardware eventually develops tarnish when the protective coating breaks down. When this happens, remove the hardware from the window and use fine steel wool soaked in a light oil or soapy water on the hardware. Restore the clean hardware’s luster with polish and then apply several coatings of a quality automobile wax.
