How do you clean a glass table without it streaking? I was cleaning MILs glass coffee table as they come home tomorrow and it was in need of a clean, but I seem to have made it look worse as it is now covered in streaks. It's a black glass coffee table and is very very glossy and reflective. I used a glass & window cleaner spray too. She is a bit of a clean freak so I need to find a way to get rid of these streaks. Help!
