Prestone Products Corp AS253 Windshield Washer De-icer Fluid

Product Description

The PRESTONE PRODUCTS CORP AS253 is a de-icing windshield washer fluid formulated for cold-weather fleet and vehicle maintenance. It is designed to remove light ice and frost on contact while resisting re-freeze on the windshield surface. The fluid remains liquid in the washer reservoir down to -34 degrees F, preventing system freeze-up during winter operation. A built-in dirt blocker additive helps repel road dirt and salt spray during driving. This product is sold as a single-gallon unit and is appropriate for any fleet technician, vehicle service professional, or facilities maintenance crew managing vehicles in cold climates.

The AS253 is suited for year-round cold-climate fleet maintenance programs, particularly in regions where road salt and sub-freezing temperatures are routine. It is applicable to passenger vehicles, light trucks, and commercial fleet units that require a washer fluid capable of handling temperatures well below the freezing point. The fluid is rated for use in standard windshield washer reservoirs and spray systems. Note: this product is not available in Texas and selected counties in Arizona, California, and Georgia due to VOC content requirements in those jurisdictions.

Installation Notes

This fluid is added directly to the windshield washer reservoir — no tools are required. Ensure the reservoir cap is secured after filling to prevent contamination or spillage. Because this product is classified as hazardous, follow applicable safety data sheet (SDS) guidelines for handling, storage, and disposal. Do not mix with washer fluids of unknown freeze-point ratings, as blending may reduce cold-weather performance.
