Question 1

What exactly is Qwix Mix?

Accepted Answer

Qwix Mix is a proportioner system that mixes tap water, methanol, and our proprietary concentrate into finished windshield washer fluid on demand — at your shop, on tap. You skip pre-mixed jugs entirely.

Question 2

How much does a proportioner cost?

Accepted Answer

System pricing depends on your gallonage and shop layout. Most single-bay shops pay back their proportioner in under a year at typical washer-fluid prices. Contact us for exact pricing on your setup.

Question 3

What do I need on site?

Accepted Answer

A wall to mount the proportioner, a tap water line, and methanol. Everything else — concentrate, hoses, nozzles — ships with the system.

Question 4

How fast is install?

Accepted Answer

Most installs are a morning of work. No special plumbing skills are required — the proportioner mounts on a wall and connects to standard fittings.

Question 5

What temperature blends can I mix?

Accepted Answer

Anywhere from +32°F to −25°F. You dial in the season on the proportioner and it adjusts the methanol ratio automatically.

Question 6

Can I run different blends in summer and winter?

Accepted Answer

Yes — that's the point. Less methanol in summer means finished fluid gets even cheaper. You control cost by controlling the blend.

Question 7

How much concentrate do I need per gallon?

Accepted Answer

Less than 1% of the finished fluid. One jug of concentrate makes hundreds of gallons of washer fluid.

Question 8

Do I need distilled water?

Accepted Answer

No. Standard tap water works. The formulation is designed for real-world water conditions.

Question 9

How long do proportioners last?

Accepted Answer

Customers routinely run the same Qwix Mix proportioner for 10–12+ years. It's a simple mechanical design with a small number of serviceable parts.

Question 10

What service does it need?

Accepted Answer

Occasional filter and seal replacement. We stock all service parts and can ship them the same day.

Question 11

What if something goes wrong?

Accepted Answer

Call us. We've been supporting these systems for 25 years — we know every proportioner in the field and can usually diagnose issues over the phone.

Question 12

Is Qwix Mix concentrate safe?

Accepted Answer

Yes. Our concentrate is 100% biodegradable and formulated to standard shop safety guidelines. Full SDS is available in the Resources section.

Question 13

How should I store methanol?

Accepted Answer

Methanol should be stored per standard shop safety practices — sealed containers, ventilated area, away from ignition sources. Your local fire code has specifics.

Question 14

Is the finished fluid streak-free?

Accepted Answer

Yes. Our concentrate is formulated for streak-free performance across the temperature range.

Question 15

How do I order concentrate?

Accepted Answer

Order directly through the online shop, or set up an account with us for recurring bulk deliveries. Most shops receive concentrate within a week of ordering.
