How do you remove black tarnish from steel window frames in my art deco era apartment?
I've gotten through the time consuming task of removing the 800 layers of what probably is lead paint, and have had some success with sanding, but it takes even longer then the stripping to get down to the shiny metal. I think this is some kind of tarnish? If so, is there a product someone could recommend, or am I committing to another 800 hours of elbow grease? Many thanks in advance!
