has the best purple rags. They are kinda high but you can clean things with NO PRODUCTS, just water. I have tons of windows and a sliding glass door and another glass kitchen door that have to be cleaned 2+ times a day. The purple rags clean them with only water and leave no streaks. It was hard to believe but it does. I don't have to buy window cleaner any more and I just toss the rags in the washer. I love her mop and refills for it are washable, no more buying swiffer pads. The initial price was a little was high but I saved because I don't have to buy cleaners. I do use a little ammonia when I mop but you could use vinegar or detergent.
