## Description

Description Aquatic Life Deionized Spot-Free Car Rinse Unit - Premium Water Deionizer for Car Washing - Spotless Car, RV, and Motorcycle Wash System. The reason you see unsightly water spots left behind after washing is from TDS (total dissolved solids) in water. If you’re looking for a quick, effective way to wash your car and avoid hard water stains, then you’ll love this inline spot free rinse system. TDS in water can vary greatly depending on the water quality in your area. To achieve a flawless, spot free shine, you need to filter out TDS from your water. That’s where this DI car washing unit comes in handy. The refillable cartridges are filled with a resin that’s charged with Cation and Anion resins. These resins filter and absorb TDS and minerals, so you’re left with clean water that’ll deliver a professional-quality car wash. Even better, when you’re finished rinsing your car, truck, RV, or motorcycle, you can let it air dry. You’ll never need to towel dry when you use this rinse system.

## Questions & Answers

**Q: Where can I get resin and what do I buy?**
A: Lots of places sell it in raw form which is by far the cheapest way to go as "the stuff ain't cheap"! Do an internet search for DI resin and you'll find several vendors. Some sell a whole cubic foot and it's $200-300 or so and will refill this kit numerous times, probably more than you need so look for a deal on like 1/4 or 1/2 cubic foot which should hold you for a couple years. You'll need the "mixed bed resin".

**Q: filtered pressure very low, removed regulator and better now, is that ok? plus I believe inlet fitting bad cause cannot stop the leak?**
A: The Spot Free Car Rinse works because the mixed bed resin removes the Total Dissolved Solids (TDS) in the water. TDS is things like calcium, that leaves spots when the water dries. For the resin to remove the TDS, the water must flow slow through the resin. If you remove the Flow Regulator, the resin will not absorb all of the TDS and you will still have spots on your vehicle. You need to keep the Flow Regulator installed. Regarding the leak, do you mean where your garden hose attaches to the unit? If so, we suggest trying some Teflon tape to stop any water from leaking.

**Q: Does the water flow through the cartridges simultaneously or in series?**
A: The water flows through the cartridges in series to allow more time for the water to interact with the mixed bed resin.

**Q: Can this be used as a hard water filter for my dishwasher?**
A: No. Use an inline water filter for a refrigerator ice maker for that purpose.
