I used it during a trip in the countryside and I must say it did clean about 90% of all the dirt from the windshield, without leaving any white traces. This ammonia-free, highly concentrated washer fluid is advertised as very good at removing bug splatter, brake dust, oil and dirt.I was curious to see what the buzz was all about so I bought this product last week to give it a try. Nextzett 92100815 Kristall Klar Washer Fluid is a fan favorite, with thousands of reviews on Amazon. Overall, I couldn’t find any fault with Prestone AS658 Deluxe 3-in-1, which is why I am rating it a 10 out of 10. So if you are asking yourself “ What is the best windshield washer fluid for winter?”, I would definitely say this one! And the best part is that you can use it all throughout the entire year, no matter the weather, or how cold it gets. Although a bit more expensive than other similar pre mixed products on the market, Prestone is easy to use, doesn’t need to be mixed with water, and is very efficient at cleaning bugs, bird droppings and dirt off the windshield. After using AS658 Deluxe for almost a year now, I can say that I am very satisfied with the high quality of this washer fluid, and how well it performs to keep the windshield clean.
I discovered Prestone at the beginning of the year when my last wiper fluid completely froze up on me during a ski trip to Aspen. If you are passionate about road trips like me, and your journeys take through different climate areas, Prestone As 658 Deluxe could be your ideal choice of windshield washer.
