Glass cleaners are specialized cleaning solutions designed to remove dirt, smudges, and streaks from glass surfaces. They typically contain a mix of water, alcohol, and surfactants, which help break down grime and provide a streak-free finish. These cleaners can be used on windows, mirrors, and other glass items in homes and vehicles. Many glass cleaners come in spray bottles for easy application, allowing users to spray the solution directly onto the surface and wipe it clean with a cloth or paper towel. Some products are also formulated to be ammonia-free, making them safer for use around children and pets.
