Window Cleaner contains no dyes, perfumes, or any other chemicals to contaminate your window surface. This is very important, as contaminants contribute to hazing! Plus, it contains no ammonia, so it is safe to use on tinted windows. When used with our Lint-Free Towels or PFM® Dual Weave Glass Towels there is no other system that will give you a cleaner, clearer, lint-free view. Period.
