New member here. I own several Tiffany-Style lamps, and it is time to give them a cleaning. From what I have gathered on the web, lemon-oil based furniture polish works well for tinted colored class and window cleaner for clear and beveled pieces in the lamp. I thought maybe someone on this forum could give me some more specific names or brands on what works best for them. You are the experts and I would rather hear from you. Thanks in advance!!
