Meguiar's Ultimate Glass Cleaner & Water Repellent is an ammonia-free formula, making it safe for both standard and tinted windows. It is designed to provide a "Level 1" hydrophobic barrier, which helps light rain bead and roll off the glass. This 16-ounce spray uses a high-output trigger to ensure an even mist, which helps prevent the liquid from running down vertical surfaces. It is a practical tool for keeping exterior glass clear while adding a layer of slickness to the surface.
Application and Usability
For a streak-free finish, it is best to use the two-towel method: one microfiber cloth to spread the cleaner and a second dry cloth to buff the surface until clear. It is helpful to avoid applying this to hot glass, as the polymers can dry unevenly and cause a slight haze. While it is excellent for exterior visibility, it is usually not recommended for interior glass where the repellent properties might interact with headlight glare at night. Specifications indicate the repellent layer typically stays effective for 2 to 4 weeks.
For those who need to protect outdoor fabrics from sun damage, the Scotchgard Sun and Water Shield provides specialized protection for textiles.
