Detailing Water Filtration FAQs
Got questions about deionised water or getting that perfect spot-free finish? We’ve got you. From choosing the right D-IonizR system to tips on saving filter life, this section covers everything you need to know before upgrading your final rinse.
What is deionized water, and why is it beneficial for car washing?
Deionized (DI) water has had its mineral ions removed, such as calcium and magnesium, which are responsible for water spots on vehicles. Using DI water for the final rinse ensures a spot-free finish without the need for manual drying.
How does the D-IonizR system work?
The D-IonizR system filters tap water through resin cartridges that remove mineral ions, resulting in pure water ideal for rinsing vehicles. This process helps prevent mineral deposits on your car's surface.
Should I use the D-IonizR system for the entire wash or just the final rinse?
It's recommended to use the D-IonizR system primarily for the final rinse. This approach conserves the resin's lifespan while still providing a spot-free finish.
What's the difference between the D-IonizR 1 and D-IonizR 2 systems?
The D-IonizR 1 is a single-stage system suitable for occasional home use, offering a compact and cost-effective solution. The D-IonizR 2 is a dual-stage system designed for higher volume usage, such as professional detailing, providing longer resin life and better performance for frequent washes.
How do I know when to replace the resin cartridges?
The D-IonizR system includes a Total Dissolved Solids (TDS) meter that measures the purity of the output water. When the TDS reading rises above 0 ppm, it's time to replace the resin cartridges to maintain optimal performance.
Can I use the D-IonizR system with any pressure washer?
Yes, the D-IonizR system is compatible with most standard pressure washers. It's designed to be integrated into your existing car washing setup to enhance the rinsing process.
Is deionized water safe for all vehicle surfaces, including ceramic coatings?
Absolutely. Deionized water is safe for all vehicle surfaces, including those with ceramic coatings. It helps maintain the integrity of the coating by preventing mineral deposits that can compromise the surface.
Does using deionized water eliminate the need for drying towels?
While deionized water significantly reduces water spots, it's still advisable to use a drying towel or blower to remove excess water, especially in areas where water can accumulate. This ensures a completely dry and spotless finish.
