DI Water Tanks for Spot-Free Rinsing — 5L to 25L

Spot Free Rinse DI water tanks are portable deionised water systems built for the final rinse after washing cars, windows, boats, caravans and solar panels. Each tank connects to a standard Australian garden hose and runs on mains water pressure — no pumps, no power, no plumbing. When the resin is fresh, output reads true 0 TDS, so surfaces air-dry with no spots, streaks or towel drying.

Which tank size is right for you?

• Mini 5L — single vehicle, occasional washing.
• Medium 10L — our most popular size, ideal for 2–3 car households and regular washing.
• Large 15L — high-volume use, mobile detailers and multi-vehicle households.
• XL 25L — commercial output for detail studios and soft-wash setups.

Resin life depends on your local water TDS — every tank includes a free TDS meter so you know when to refill. All tanks are refillable, pressure-washer compatible, assembled and tested in Australia, and ship free Australia-wide.
