emperors61 Posted November 22, 2021 Share Posted November 22, 2021 Hi, To better maintain the opti glass coating (consumer version) on my exterior glass surfaces I was wondering if I could add the Optimum Opti Glass Clean & Protect Concentrate at the right dilution rate to my windshield wiper fluid? Also, would it work with various winter windshield wiper fluids as well? Quote Link to comment Share on other sites More sharing options...
