Using a dry soft lintfree cloth and mild spray solution, wipe the cloth in circular motions to remove any dust or marks on the frame. Never spray any cleaning solution directly onto the glass, glazing, or other frame elements. Always spray onto the cleaning cloth, letting the air hit the damp cloth for a few seconds before making contact. Be sure to continue rubbing until the solution evaporates completely from the surface of the frame. Alternatively, use a duster for daily cleaning.
