Windshield Washer Fluid Concentrate, 1 Bottle Makes 32 Gallons, 1/4 oz. Makes 1 Gallon 100% Biodegradable

Loved thisBeen using Waze for all my vehicles for the past year and a half did not cause any problems. Does not smell. Does an OK job as a windshield washer

Practical product

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 furnitureThey 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.

Basically a lifetime supply of blue grade washer

I use a LOT of wiper fluid, as I park my truck outside under a tree that loves to spray pollen. This concentrate works extremely well, leaving no streaks and effectively removing sticky residue, pollen, and dirt.

Work but freezed sometime

Does the job well, saves a ton over non-concentrated retail cleaners. I add a bit od alcohol. Nothing better than cleaning whilst inebriated (joke).
