1-Gallon Windshield Washer Fluid Concentrate, Makes 500 Gallons, Biodegradable Bug, Grime & Dirt Remover Fluid, Commercial-Grade Streak-Free Glass Cleaner for Cars, Trucks & Fleets

Love this fluid concentrate. Does a great job cleaning and way cheaper than buying those gallon premade ones. I like how the bottle is made as it comes with a measurement, easy to pour into a1 gallon of water. Would get again.

Great product i baught durring the ahipping problems when covid started and everyone was buying online cause my area couldnt get wiperfliud brought in enough and i couldnt find any. Ive had the bottle for years and it last a long time. Its a great way to save money and less plastic waist i use an old washer fluid bottle to mix and get the right mix.

I can’t believe I hadn’t discovered this before. If you are buying washer fluid by the gallon, you’re buying mostly water but last time I checked was pretty inexpensive from the tap. I just put in the recommended amount into the reservoir and then add water to fill. It takes up less space on the shelf too.

This contains biodegradable surfactant (soap) and dye. That's it. Those ingredients will: - wet your windshield and provide a very mild cleaning action - prevent bacteria and other biological stuff from growing in your washer fluid reservoir - give you a warm and fuzzy feeling that you are not dumping toxic material into the environment - in the concentrated form, stain anything blue like your hands and furniture They won't: - prevent it from freezing. This is clearly stated in the product description - make a real window cleaning solution, like Windex (which you don't really want) All the reviews about it freezing are because people can't read directions. That said, this doesn't need dye, it's just another environmental hazard and waste. Compared to pre-mixed off the shelf washing fluid, I did a side by side comparison and it pretty much performed the same when mixed in the recommended ratio. It did not "clean bugs off my windshield" but then again none of the other ones did. I would give 5 stars but the ridiculous amount of blue dye .... -1.

Very good product it gets off all of bugs and road ground off the windshield. I will keep buying this product. next purchase will be in a gallon job.

Not buying windshield wiper fluid any other way. Love how small the container is and how long it lasts. Very easy to use.

This is by far the worst windshield washer fluid concentrate I have ever used. First, it leaves horrible deep-blue stains on the car’s paint. If any overspray hits the hood, fenders, or mirrors, it dries into ugly blue streaks that are difficult to remove, even with proper car wash soap. This is completely unacceptable for a product that is sprayed directly onto your windshield and surrounding body panels. Second — and far worse — this product FREEZES at temperatures that are only slightly below freezing, despite being marketed for cold-weather use. This caused my washer fluid system to freeze, which can damage the pump, tubes, and spray nozzles. A washer fluid that freezes defeats its entire purpose and can lead to expensive repairs. Between the paint-staining dye and freezing issues, this product is unsafe for your vehicle and not worth the risk. Do yourself a favor and avoid this product. There are many better and safer alternatives.

Works great but the below freezing recommendations are not correct. You need twice as much recommended methanol to keep from freezing at -25 degrees. Found out the hard way. Value per gallon is phenomenal, color matches, its longevity is great, smell is minimal, its cleaning ability is subpar.
