Qwix Mix 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.

Those saying you're better off buying the jug of washer fluid bc you have to buy the methanol just don't get it. This stuff will save you money by not buying jugs and jugs of washer fluid Everytime you run out. It's so concentrated you only need a few oz per gallon. You can do the math. It wipes and cleans the windshield very well; in rain, dirt, bugs and other grime. I also added rainx water beading solution to also help out the effect . Very easy to mix but watch out getting it on your hands, it does have dye in it so it'll stain very easily on your fingers if it spills.

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.

This is a great product my Mercedes holds 5 gallons of windshield wiper fluid so it cost me pennies to mix this. Strongly Recommend

Easy to add to the washer fluid tank.....no funnel needed

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.

Very sensitive product. I recommend you wear disposable gloves. Immediately it stained my finger when I had open up the bottle. I don’t know how it does on clothing, but be very cautious when handling this product. When I used it on my windshield, I can clearly see the blue water. It does clean well with no issue whatsoever. It’s also staining the wipers. I may have to adjust the ratio when I refill the reservoir next time. I’ll update my rating then. However 3/5.

Works well as far as I am concerned.
