Prestone AS240 Windshield Washer Fluid Booster De-Icer Additive - 15.5 oz.
Engineered to quickly remove light ice and frost and helps to repel build-up of dirt and salt from road spray as you drive. Also helps prevent dangerous re-freeze from forming on your windshield. A precise blend of ice-melting alcohols ensures premium performance at even very low temperatures and helps prevent dangerous re-freeze from forming on windshields. Prestone's Dirt Blocker technology coats windshields with a resilient organo-modified siloxane copolymer. This formulation imparts a durable hydrophobic surface on the windshield that helps prevent road spray from adhering to windshield glass by moving dirt particles away from the windshield surface and into the washer fluid that beads and rolls off the glass. The robust formula is designed for use with any washer fluid to provide premium performance.
