What was thought to be a patina original to the design was a combination of slight oxidation, tarnish, and a heavy hardened tar residue that was caused by previous policy of allowing smoking indoors. A combination of inherent moisture in the air and tar residue caused dust particles to adhere to all horizontal metal surfaces.  

Focusing on one fixture at a time, all glass components were removed, cleaned and buffed, then set aside.  With glass safely set aside OnAim utilized a small shop vac, chip brush, and a soft bristle toothbrush to carefully remove all dust and dirt particles. The structure was then cleaned and polished using metal polish, steel wool, and cloth rags.
