The next best thing to a helper that hides in a magic lamp, the E-Cloth Window Genie is your shortcut to perfectly clean windows and glass. The comfortable mitt erases streaks, light grease, and dirt, for a sparkling finish. All you add is water. (Those blue sprays make us uneasy, too.) Rows of pleats each packed with precision-engineered microfibers grab grime, dust, and smudges with just a swipe or two. No, follow up necessary for a streak-free, lint-free finish. To refresh, just toss in the laundry.
