Keeping your windshield clean is important for your safety and for the safety of others on the road. The following cleaning tips will keep your windshield in top condition: Be sure to lift the windshield wipers off of the glass to clean underneath and around wipers for hidden debris. Spray hard-to-remove debris directly with a glass cleaner and carefully use a razor blade at a 45-degree angle. Leaving insects, tar or tree sap on the windshield can leave streaks that are difficult to see through. To clean wiper blades, use a microfiber towel soaked with concentrate. Be sure to replace worn wiper blades to prevent scratching. For extra protection, apply the Formula 1 Glass Cleaner with Rain Repellent to improve your visibility in rain and snow.
Remove seal and squeeze concentrate into bottle chamber from the bottle bottom until the concentrate reaches the 1/2 mark on the chamber. Add three doses of concentrate directly to the car's windshield wash fluid container and fill remainder with water. Three doses of concentrate makes 1 gallon (4 liters) of windshield wash.
