    Mixing Instructions

    Please use the following mixing ratios based on the level of freeze protection you need. Consider any existing summer windshield washer fluid currently in your washer fluid tank if you do not intend to drain it first when determining your mixing ratio. While compatible with all brands of washer fluids, we recommend you drain your washer fluid tank first for the most accurate Anti-Frost washer fluid mix.

    Most washer fluid tanks are 1 - 1.5 gallons (3.8-5.7 liters) in size. Please contact your dealership for exact capacity.

    Anti Frost + Water = Temperature Protection

    The Only Biodegradable Commercial Option!

    This stuff works and is the only biodegradable winter mix available commercially. It is worth the extra price instead of poisoning the planet and everybody living on it.

    Both bottles cracked upon receipt

    Product itself is fine. Both bottles had cracked on the bottom edge, where molding seams were located. The bottles were wrapped tightly so it was not an issue as far as shipping went, but I unwittingly unwrapped both bottles before I was ready to use them, and they were leaking. I have to store them upside-down until I'm ready to use.

    Great product

    Great product, does not leave streaks and smels great. Used it durring the winter and performed very well. More expensive than the cheap alternative but definitely worth the extra cost. Will buy again for next winter to replenish my stock in the garage.

    Cleans well for my Porsche.

    Cleans well for my Porsche. I mixed roughly 50:50 with existing factory antifreeze. Driving at 70mph with below 0F temperature still caused icy streaks, no issue with sprayer nozzles. First shipping package had leaked, but Nextzett shipped another set for free with extras wrapping and protection. 5 stars for service alone.
