Review on 🔍 Optimum (3873) Opti-Glass Cleaner & Protectant - 17 oz. by Thomas Drew

I was so pleased with the OPT ONR Wash and Wax that I decided to give it a try. Coped with a couple of weeks of winter turbulence and rain with ease. I did not clean the passenger side windshield to compare with RainX washer fluid. Freeway. It outperformed RainX, not by leaps and bounds, but better. I applied RainX washer fluid to the windshield and OPT still performed better than RainX.
