I have light polls out side my house made from copper. Copper has a green tint around that outside and inside which I have removed however the glass now has a tint kind of like a film built where the glass slides into the copper holder. How do I removed the film. I have used Windex, Foaming Cleaner, Goop, Orange cleaner, Mineral Spirit and even laquary thinner. Oh and WD-40 still this film will not move even a razor blade and it stays just scratch my glass. Any thing else anyone knows.ThanksDavid
You should have just left them as they were. That green tint is called patina and it will come back. The nice thing about patina is that it prevents further corrosion and gives the copper an aged look. Most people who install new copper roofs or fixtures outdoors spray them with a solution that causes a patina to form immediately. Very very fine particulates of it have embedded themselves into the glass and you will almost certainly need to replace the panes if you want to get rid of it. If you insist on keeping patina off of your copper poles, the poles will eventually run out of copper and end up full of holes. I suppose that you could have your pristine copper poles clearcoated but this will not be a permanent solution as it will flake off in time like any paint. If you really want them to last, just leave them be.
