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.
Resin life depends mainly on your local water quality — specifically the TDS (Total Dissolved Solids) of your tap water. Higher TDS means more dissolved minerals for the resin to remove, so the resin will be used up faster. As a real-world example, we achieved ~500L from a 6L tank on ~290ppm input water.
Estimated output at ~100ppm input water (approx.) and using 30L per rinse:
- 6L: (1,350–1,500L): 45–50 rinses
- 8L: (1,950–2,200L): 65–73 rinses
- 10L: (2,550–2,900L): 85–97 rinses
- 15L: (4,000–4,500L): 133–150 rinses
Australian town water often sits around 50–300 ppm, depending on your location and water source. Some areas are lower, and others can be significantly higher
Tip: Wash with normal tap water, then use Spot Free Rinse only for the final rinse. This stretches resin life significantly.
These figures are estimates because water quality varies. Check your output TDS periodically—when it rises or spots start to appear, it’s time to replace the resin.
We’re here for you. Whether it’s help setting up, refilling resin, or just questions about using your tank — shoot us an email or message, even give us a call if you need. We're a small Aussie business and pride ourselves on our relationship with our customers. We will ring you a few weeks after you receive your tank to see how it's going, if you have any questions or suggestions on improvement.
Yep! We ship all across Australia. Orders usually ship within 1–2 business days.
No — use cold tap water only. Hot water can damage the resin and reduce its performance and lifespan.
Each tank includes standard Aussie garden hose fittings. Just connect your regular garden hose to the inlet and attach your spray nozzle or pressure cleaner to the outlet. Simple as that.
100%! Purified water is actually safer than regular tap water because it contains no minerals — meaning no streaks, no spots, and no residue.
It’s safe on:
- Paint and clear coat
- Glass and mirrors
- Chrome, stainless, and aluminium
- Plastic trims and lights
- Solar panels and more
Absolutely. All Spot Free Rinse tanks are refillable. Just unscrew the cap, extract the old resin, and refill with fresh resin. We sell refill kits with all tools and detailed instructions (including a video).
A DI (Deionised) water system uses specialised resin to remove all minerals and impurities from tap water. When you rinse your car, windows, or solar panels with DI water, it evaporates completely clean without leaving water spots or mineral deposits.
Resin life depends on your local water TDS, usage volume, and system size. Higher TDS water will consume resin faster. Many users monitor output with a TDS meter to know when to replace. Check out our website's FAQ page for a easy to use calculator and more information.
Choose based on your water TDS and how often you rinse. Higher TDS or more frequent washing benefits from a larger tank to extend resin life and reduce maintenance.
