Qwix Mix Windscreen Washer Fluid Concentrate — 1 Bottle Makes 32 Gallons, Biodegradable Super-Concentrate

Qwix Mix windshield washer fluid concentrate is a super-concentrated formula that lets you mix a full gallon of windshield washer fluid with just 1/4 oz, stretching one bottle into 32 gallons of ready-to-use cleaner.

Save space, shipping cost, and single-use plastic by creating windshield washer fluid at home or in your shop. This concentrated solution is formulated to cut grime and road film while being biodegradable and manufactured in the USA. For cold climates, add methanol per the mixing chart to provide freeze protection; do not use this concentrate alone in freezing temperatures.

How do I mix Qwix Mix so one 1/4 oz makes a gallon?

Mixing Qwix Mix is straightforward: measure 1/4 ounce of concentrate into one gallon of water to produce a ready-to-use windshield washer fluid. Use a clean measuring device or the included dosing guide, and stir or shake the container to fully incorporate the concentrate.

• Ratio: 1/4 oz concentrate per 1 gallon of water.
• One full bottle yields approximately 32 gallons when mixed at that ratio.
• Use distilled or tap water depending on local mineral content.
• Label mixed containers and date them for inventory control.

Will this product work year-round and how do I avoid freezing?

The concentrate itself is designed for cleaning year-round but requires added methanol to prevent freezing in winter. Follow the product’s mixing chart to select the correct methanol amount for your expected low temperatures; never use the concentrate without methanol where temperatures drop below freezing.

• No added methanol: suitable for non-freezing seasons or indoor use.
• For winter: add methanol per the chart to reach desired freeze point.
• Do not use automotive antifreeze products unless specified by the manufacturer.
• Store methanol and concentrate safely according to local regulations.

How does using a concentrate save money and space for fleets or shops?

Concentrates eliminate shipping and storage of water weight, reducing cost per gallon compared with pre-mixed jugs. One compact bottle replaces many bulky containers, cutting plastic waste and freeing shelf or vehicle trunk space for other supplies.

• One bottle mixes into 32 gallons—fewer deliveries and less storage footprint.
• Lower shipping costs because you’re not paying to ship water.
• Perfect for garages, service shops, and light fleets needing frequent refills.
• Mix on demand to avoid waste and overstocked premix jugs.

Is Qwix Mix safe for wiper systems and the environment?

Qwix Mix is formulated to be biodegradable and safe for standard windshield washer systems when mixed as directed. It cleans residue and dirt effectively while minimizing environmental impact compared with some traditional formulations.

• Biodegradable formula manufactured in the USA.
• Compatible with typical windshield washer pumps and nozzles when properly diluted.
• Gentle on wiper blades when used at recommended concentrations.
• Follow disposal and handling guidance to comply with local regulations.

Who is this for: Qwix Mix is ideal for car owners who want to cut recurring costs, fleet managers and repair shops needing efficient bulk solutions, and eco-conscious drivers looking to reduce plastic waste. If you mix fluids at home, maintain a service garage, or outfit multiple vehicles, this concentrate gives control over freeze point and cleaning strength while saving space and money. Remember to add methanol for winter freeze protection and always follow the provided mixing instructions and safety guidance.
