Looks Like Water Dried On, But Not Water on Sliding Glass Door
Help me clean my sliding glass door. It is hard to describe what is going on. It looks sort of like someone sprayed the glass and let it . It has a water spot appearance. I am not saying that is what happened, but to give you some kind of visual. I have tried to clean it, but no luck. Vinegar and water will not clean it. There is so build up of anything so nothing to scrape off. The glass itself just seems to have this look of something sprayed on and dried on. Suggestions for getting it off. I have used a microfiber cloth, too.
