Ceramic Glass cleaner is easy to use and gives excellent results leaving the glass clean and smear free. Ceramic Glass cleaner adds a layer of hydrophobic protection which allows water to bead effortlessly off the glass. I would definitely recommend this glass cleaner and I feel that it is one of the best glass cleaners I have used to date and it is even more impressive when used in conjunction with the Auto Finesse Ceramic Glass Kit. I am a big fan of Auto Finesse products.
