The grime-grabbing, textured waffle-weave side grabs dirt, dust and fingerprints. The smooth side soaks up excess moisture and swallow smears and fingerprints for a streak-free finish. With masses of precision-engineered microfibers activated by water’s cleaning power, there’s no need to worry about blue mystery sprays. And with our 3-year or 300-wash promise, you may never put paper towels in your shopping cart again.
