Can Patio Doors Be Saved?
Hi, I just rented an older Townhouse and the patio doors are a mess! Half of the glass on the doors are white and you can no longer see out of them.It looks like a very bad case of soap scum but I doubt that's what it is. I've read about oxidation, mineral,and hard water buildup. I've also read about grade 2 degradation. How do I know which situation I'm dealing with? How can I clean them, if they can be cleaned at all?
