Rain‑X Washer Fluid Additive enhances the performance of any windshield washer system, simply add it to water or your preferred washer fluid. The formula boosts cleaning power and helps repel rain by causing water to bead up and blow away with the airflow over your windshield. This improves visibility, safety, and overall driving comfort in wet weather.
For best results, mix approximately 100 mL of additive with 3 L of water (or washer fluid). Shake or stir the mixture briefly to ensure even distribution before filling your vehicle’s reservoir.
