How it works

Three lines in. Any blend out. On tap, on demand.

No mixing by hand. No jugs to lift. A Qwix Mix proportioner meters your three ingredients and pours finished fluid into whatever container you put under the tap.

The three inputs

Things you already have. And one you don't.

Tap water

70–99%

Most of the finished fluid. Stop paying to ship it in.

Methanol

1–29%

The freeze-point control. More in winter, less in summer.

Qwix Mix concentrate

< 1%

Our proprietary blend of detergents and additives — the streak-free magic.

Three supply lines feed the proportioner. One tap pours finished, ready-to-use windshield washer fluid.
Set your season

Dial in the temperature blend.

Turn one knob to pick your freeze point. The proportioner adjusts the methanol ratio automatically.

Temperature range
Summer
+32°F

Minimal methanol. Bug wash and streak-free glass.

Shoulder
0°F

Balanced blend. Handles overnight freezes.

Winter
−25°F

Full methanol. Ready for the coldest mornings.

You control the cost by controlling the blend. Less methanol in summer means finished fluid gets even cheaper.

Install

A morning install. Years of service.
