Use a telescopic mop handle and aluminum flat mop frame with velcro strips, stick a damp little waffle cloth onto the velcro strips and proceed to wash glass panes, then take off the damp cloth and stick on a dry little waffle cloth to polish off for a perfect streak free finish, if you have to deep clean metal frames just rub them with a damp magic eraser pad to remove ingrained soils and again just wipe over with a dry little waffle cloth to achieve a streak free finish on the framework, this method is quick and easy while leaving no drips or splashes.
