Qwix Mix Windshield Washer Fluid Concentrate — 1 Bottle Makes 32 Gal, Biodegradable, Super-Concentrated

Qwix Mix windshield washer fluid concentrate is a super-concentrated, biodegradable formula that dilutes to make up to 32 gallons of windshield washer fluid so you can mix your own by adding water (and methanol for freeze protection).

This concentrated washer fluid is designed to cut the cost and shipping waste of pre-mixed jugs. A small measured dose—approximately 1/4 oz per gallon—creates a cleaning solution that removes road grime, bug residue, and light film from glass when used with a vehicle's washer system. The concentrate is formulated in the USA and breaks down naturally, making it a practical choice for shops, fleets, and households that prefer to prepare fluid on demand.

How much washer fluid does one bottle actually produce?

One bottle of Qwix Mix is highly concentrated and dilutes to produce a large volume of ready-to-use washer fluid. Use the recommended measuring ratio—about 1/4 ounce of concentrate per gallon of water—for typical cleaning and streak-free performance. Exact yield depends on how strong you mix it, so you can stretch one bottle for lighter cleaning or make a stronger mix when needed.

• Yields up to 32 gallons based on the standard dilution ratio.
• Approximate dosing: 1/4 oz concentrate per gallon of water.
• Mix more concentrated for heavy grime or bug-removal tasks.

Do I need to add anything for winter use?

This concentrate requires adding methanol if you plan to use it in freezing temperatures; the base formula does not provide freeze protection. Follow the mixing chart to achieve the freeze point you need—add methanol in the correct proportion before storing or using in cold weather. Never use the product in subfreezing conditions unless methanol has been added to the mixture.

• Add methanol per the supplied mixing guidance for winter protection.
• Do NOT use undiluted concentrate in frozen conditions.
• Store methanol and finished winter fluid safely and away from heat sources.

Is this safe for my car and the environment?

Qwix Mix is formulated to be biodegradable and gentle on windshield washer systems while still removing common road soils. It’s made in the USA with ingredients chosen to balance cleaning power and environmental breakdown. As with any automotive fluid, use as directed and avoid contact with painted surfaces or rubber trim in undiluted form.

• Biodegradable formula reduces environmental persistence.
• Designed for compatibility with standard washer systems and wiper blades.
• Rinse spills and avoid concentrated contact with vehicle paint and trim.

Why choose concentrate instead of pre-mixed jugs?

Concentrates cut cost, shipping water, and storage bulk by letting you mix only the volume you need. This approach is especially economical for garages, fleet operators, and home users who refill frequently. Fewer jugs means less plastic waste and lower transport costs per gallon of final fluid.

• Lower per-gallon cost compared with pre-mixed fluid.
• Less plastic waste and fewer storage jugs required.
• Flexible mixing strength for light cleaning or heavy-duty jobs.

Who is this product for? Qwix Mix windshield washer fluid concentrate is ideal for car owners who want to save money and reduce waste, automotive shops and service centers that refill customer reservoirs, and light fleets that need an economical, storable solution for frequent top-offs. It also suits DIYers who prefer to control dilution and freeze protection; just remember to add methanol for cold-weather performance.
