Spot Free Rinse Purification Tank
🔒How long will it last?
Estimate rinses and litres based on your water and usage.
Tap water contains minerals like calcium, iron, and magnesium — the cause of those frustrating water spots, also known as limescale or mineral deposits. Miss a spot when drying, or skip drying altogether (we're all time poor), and over time those deposits will damage glass and paintwork.
Our Spot Free Rinse tanks use deionising (DI) resin to strip those minerals out, giving you pure, spot-free water for a crystal-clear finish — no wiping, drying, or polishing needed. Just rinse and walk away.
Important: this system is designed for the final rinse only — not the full wash.
Using it for the entire wash will exhaust the resin significantly faster. All lifespan and capacity figures are based on final-rinse use only.
Here's how to get the most out of it:
- Washing undercover? Use your regular tap water for the main wash, then switch to Spot Free water at the end to rinse the tap water off.
- Washing in full sun? Work one panel at a time — wash a panel, then rinse it before moving on.
To get even more life out of your resin, use the bypass valve for your main wash and only switch to the DI output for the final rinse. This keeps resin consumption to an absolute minimum.
The tanks are portable, compact, and compatible with a pressure washer, regular hose, or water fed pole. You can rinse in full midday sun and still get zero mineral deposits.
Choose the right size
Most people use up to 30 litres per car rinse. The right tank size for you depends on three things: how often you wash, your local water quality (TDS), and the tank size you choose.
Every tank includes a TDS meter so you always know where your resin is at. When purified water starts reading above ~10 ppm, or you notice very light spotting, it's time for a resin replacement. All tanks arrive pre-filled with premium high-flow resin, ready to use straight out of the box.

Spot Free Rinse Purification Tank
Pure Water. Zero Spots. No Drying.
See why hundreds of Aussies are ditching the chamois and letting their cars air-dry with a perfect finish.
Tap Water Leaves Spots
Tap/Tank/Bore water is full of dissolved minerals. When it dries on your car, windows, or solar panels, those minerals are left behind as lime scale/water spots.
Spot Free Rinse Purifies Your Water
Connect to your hose and rinse. As water flows through the tank's resin, every dissolved mineral is removed — leaving 100% pure water.
Spot-Free. No Drying Needed.
Just wash, rinse, & pack up, let it air-dry. Pure water leaves zero residue — a flawless finish every single time.

Size Guide
Bigger tanks last longer for two reasons.
Water flows through the resin from the top down.
The top resin wears out first, while the bottom can still be fresh.
When you start seeing spots, the resin isn’t fully used up — it’s just no longer producing perfectly pure water.
A bigger tank has a deeper resin bed, so it keeps producing spot-free water for longer and lets you use more of the resin before a refill.
Example: The Medium has twice the resin of the Mini, but in real use it typically lasts around 130% longer, not just 100% longer.
Mini
Best for single-vehicle households who washe occasionally. The Mini tank provides enough pure-water capacity for periodic cleans without taking up space. Compact, portable, and budget-friendly — the easiest way for first-time users to experience spot-free rinsing at home and see the difference pure water makes.

Frequently Asked Questions
Everything you need to know about this product
How long the resin lasts depends on three things: the tank size you choose, how much you use it, and your local water quality (TDS). You need to choose the right tank for your usage, so you’re not replacing resin too often or paying for more capacity than you need.
We have a calculator above and on our FAQ page to help estimate how many rinses/litres you can expect. Just enter your details for an approximate result.
Every tank includes a TDS meter, so you can check the purified water yourself rather than guess when the resin needs replacing. As a guide, when the output starts reading above 10 ppm, or you begin to notice very light spotting, it’s a sign the resin is nearing replacement time.
Resin life ultimately comes down to your usage and the tank size you chose. Larger vehicles, heavier rinsing, longer hose runs, and higher TDS water will use resin faster, and some people go through more water than they realise. If you use more water or choose a smaller tank than your workload requires, resin changes will be needed sooner.
For maximum resin life, wash as normal and use Spot Free Rinse for the final rinse only, straight after washing and before the tap water/detergent has a chance to dry.
To show you the scale, ion exchange resin ranges from cheap generic grades right through to ultra-high-purity resin used in semiconductor and nuclear water systems.
Most other systems send you the individual parts and you need to assemble and fill the tank yourself. Our systems come fully assembled, you are not part of the assembly line.
All other resins we tested were the cheap generic type. They worked for the first few washes, and they exhausted very quickly and cannot keep up with the flow required for car washing. We don't sell the cheap, generic cleaning resin. We build high quality products designed to perform in the real world, not gimmicks
Yes!

contains no minerals — meaning no streaks, no spots, and no residue.
It's safe on:

- Glass and mirrors
- Chrome, stainless. and aluminium
- Plastic trims and lights
- Solar panels and more
Yes! This is one of the best things about a Spot Free Rinse tank.

With Spot Free Rinse, because the water is completely mineral-free. it won't leave any residue as it dries - even if you're out in the sun. Just make sure you rinse the soapy water before it dries.
