Promising review: “Wonderful. I’m never using window cleaner and paper towels again for as long as I live!!! OMG, these things are a miracle. I’ve always hated cleaning my windows and shower because it was such a pain to get it streak-free, and I hated using rolls and rolls of paper towels to do it. After having cleaned the windows inside my car and doing such a poor job recently, I took my car to the car wash mainly to have them do that. As I was waiting for them to finish up, I started to wonder what they were using to clean the windows because they did it fast, left no streaks, and only used rags. I had used rags in the past with terrible results. When I got home, I started researching it and found these. They work unbelievably well, and I only have to use water??? Who would have known. I’ve used them on my shower, windows, glass, and even my stainless steel appliances. I hate cleaning my appliances!!! The only thing I ever found was polish, which was an absolute hassle and time consuming. Well, THIS WORKED FOR THAT, TOO!!! It was easy, only had to use water and gave an excellent result. I wish I had figured this out a long time ago and saved myself a lot of time and irritation.” —Amazon Customer
