What car owners are saying

Rated 4.9+ out of 5 by verified buyers

I’ve owned prestige cars for 20 years and love this product! Not needing to wipe down my cars after washing and having them dry naturally, spot free, is a game changer.

The calcium halo

Isn't water just water?

Why would anyone filter the water they wash their car with? Fair question. Tap water looks clean, but it carries dissolved minerals, and they stay behind when the water dries.

  1. A drop of tap water on car paint, carrying dissolved minerals

    Every drop carries minerals

    Tap water is full of dissolved calcium and magnesium you can't see.

  2. The drop has dried and left a white mineral spot on the paint

    It dries to a white spot

    The water evaporates and the minerals stay on the paint or glass.

  3. A cloth has wiped the white spot away but a thin mineral ring is still stuck to the paint

    The halo stays

    You wipe the spot off, but a thin ring stays stuck to the surface. We call it the calcium halo.

  4. A new water drop has stopped on the old mineral ring and will dry in the same place

    The next drop stops there

    The next drop catches on that ring and dries in the same place. Wash after wash, they build up.

Hand wiping a car window with a red microfibre cloth, with mineral spots still left on the glass

Soap and water won't shift it

A cloth and soapy water slide straight over a halo, the same way they never quite get a shower screen clean. Halos sitting on a ceramic coating stop it beading like it did when it was new.

Check your own car

Clean one window, then look at the sun's reflection in the glass. See rings or haze in the glare? Those are calcium halos.

Pure water leaves nothing behind, so no new halos form.

It won't remove halos that are already there. That's a job for a detailer and a polish.

FOUNDER DISCOVERY

From Racing the Sun to Spot Free Rinsing

A simple accident with purified water revealed a better way to wash cars without spots, streaks or drying.

Spot Free Rinse started when purified water accidentally splashed onto my car and dried perfectly spot free.

After years of dealing with streaks and avoiding the sun, I found a better way. Less contact means less chance of scratching.

When nothing suitable existed in Australia, I built a compact DI rinse system designed to deliver a flawless finish, with no drying required.

"Water should finish the wash, not create more work. I simply found a way to let it dry perfectly on its own."

Frequently Asked Questions

Everything you need to know about DI water systems.

Pop your postcode into the “How long will a tank last me?” calculator and it works out the rinses for your water. More cars, harder water or more washes means a bigger tank goes further between resin replacements.

More on the tank page →

It depends mainly on your tap water. At about 100 ppm the Lite does 85 to 97 final rinses per resin set, and at 200 ppm about half that.

More on the tank page →

Yep. Orders ship within the next business day and most arrive in 2 to 5 business days (WA, allow 5 to 8), with free shipping on the Lite and Pro tanks, pole kits and bundles. The Commercial ships by courier, and we confirm the freight cost when you order.

Absolutely. Our resin replacement kits include everything you need except a pair of scissors, plus step-by-step instructions and a video.

Every tank comes with standard Australian garden hose fittings: your tap goes to the IN side, and your hose or pressure washer goes on the OUT side. With a pressure washer it's tap, tank, then pressure washer.

A DI (deionised) water system uses resin to pull the dissolved minerals out of your tap water. Rinse with it and the water dries without leaving spots or mineral deposits behind.

Yes. Purified water has no minerals in it, so it leaves no spots, streaks or residue on paint and clear coat, glass, chrome, stainless, aluminium, plastic trims, lights or solar panels.

No, use cold tap water only. Hot water can damage the resin and shorten its life.

We're here for you.
