Glass/hard surface cleaner features a concentrated, effective formula that quickly dissolves films, smears and fingerprints to leave your surfaces with nothing but a streak-free shine. Its dual-acting design deposits an invisible coating after each cleaning that resists re-soiling to minimize the need for frequent cleanings. Simply drop one pre-measured PAK-IT into its matching trigger-spray bottle (sold separately) and add 32 oz. of cold, tepid or warm water. For crystal-clear results, use a single spray of fine mist and wipe off with a clean microfiber cloth or paper towel. Ammonia-free cleaner is perfect for cleaning all nonporous, hard surfaces including glass, mirrors, windows, marble and more.
