# Prestone Windshield Washer Fluid De-Icer Additive *Published: 2026-01-29 | Updated: 2026-01-29 | Source: https://shopsavvy.com/products/prestone-windshield-washer-fluid-de-icer-additive* --- **Brand:** Prestone **Price Range:** $3.69 - $72.67 across 24 retailers ## Pros - Effectively prevents windshield washer fluid from freezing, even in temperatures well below freezing. - Cleans windshield satisfactorily, loosening dust and dirt to improve visibility. - Offers an economical alternative by letting you make your own washer fluid instead of buying expensive pre-mixed gallons. - Each 15.5 oz tablet dissolves in a gallon of water to create ready-to-use screenwash, saving money and reducing plastic waste. - Reliable and consistent performance reported by users, including in snowy and freezing conditions. - Helps prevent wiper fluid lines from freezing and reduces ice buildup on windshield wipers. - Useful as a winter additive to maintain washer functionality for cars and heavy-duty trucks. - Provides substantial yearly savings by allowing homemade screenwash production. ## Cons - Takes a few hours after pouring in to become fully effective, so it’s not instant. - No additional features or benefits beyond standard washer fluid booster and de-icer function. - Performance is basic and purely functional without extra perks like pleasant fragrance or advanced cleaning agents. ##
