Our Z Clear Spray is designed for easy application. Made with the same Z Clear solution to clean all lens types without causing any damage. This oleophobic solution will help repel fingerprints, dust, dirt, and oils, as well as preventing condensation and moisture from adhering to the lens. The Spray is easier to apply to large surfaces, and is a safe method for cleaning lenses you want to avoid touching. Continued use creates better and longer lasting results.Our Paste is designed to do two very unique things. First, it's highly condensed so it's a bit stronger than the typical spray. Second, it's designed to fill in scratches similar to how you would fill in scratches on a CD with toothpaste!
