High-Capacity 817 DI Spotless Water Unit with Mixed Bed Resin, 10" PP Pre-Filter, Pressure Gauge & Full Connection Accessories – Professional Car Wash & Mobile Detail System

• Step 1: Rinse the vehicle with tap water to wet the surface

  This first step is all about getting the car ready for cleaning.

  Use a regular garden hose with tap water to spray the entire car, starting from the roof and working down to the wheels. The goal is to wet the paint completely and wash away loose dirt, dust, and small debris. This prevents you from rubbing grit into the paint later, which can cause scratches. Make sure every part of the car, including the wheel wells and lower panels, gets fully wet.

• Step 2: Apply the cleaning solution onto the sponge and wipe it onto the car

  Now it’s time to clean the car with soap.

  Mix your car wash solution with water in a bucket, then soak a soft sponge or wash mitt in the soapy water. Gently wipe the car from top to bottom, using straight, light motions. The soap will break down road grime, bugs, and dirt that the first rinse didn’t remove. Always keep the sponge wet and rinse it often in the bucket to avoid picking up dirt that could scratch the paint.

• Step 3: Rinse off the soap suds using tap water

  After washing, you need to get all the soap off the car.

  Use your garden hose again with tap water to rinse the entire vehicle, still working from top to bottom. Make sure every trace of soap suds is washed away, including from door handles, window trim, and crevices. If soap is left on the car, it can dry and leave streaks before the final rinse. This step leaves the car clean but still wet and ready for the spotless finish.

• Step 4: Use a water deionizer to rinse the vehicle, leaving a spotless finish

  This is the key step for a spot-free shine, using your water deionizer.

  Connect your water deionizer to the hose, then rinse the entire car slowly with the deionized water, starting from the roof and letting the water run down. Since deionized water has no minerals, it won’t leave water spots when it dries. You don’t even need to towel dry the car—just let it air dry naturally, and you’ll get a crystal-clear, spotless finish.

• Pre-Filtered Design to Extend Resin Life

  Unlike basic DI systems that skip pre-filtration, our kit includes a 10" blue filter housing with a PP sediment filter to trap dirt, rust, and debris before water reaches the mixed bed resin. This prevents resin fouling, doubling the lifespan of your expensive resin and saving you money on frequent replacements.

• 0 TDS Spot-Free Rinse Guaranteed

  Premium mixed bed ion exchange resin removes 100% of dissolved minerals (calcium, magnesium, iron) from tap water, delivering pure 0 TDS water. Wash and rinse your car, RV, boat, or windows and let it air dry completely—no wiping, no streaks, no water spots, even in the hardest water regions.

• Durable 817 FRP Tank with Safety & Convenience

  Built with an industry-standard 8x17 NSF-certified FRP tank rated for 100 PSI, this system includes a precision pressure gauge to monitor water pressure and prevent overloading. The heavy-duty stainless steel carrying handle makes it easy to move between jobs or store in your garage.

• Universal Compatibility & Complete Kit

  Comes with 3/4" brass garden hose fittings, a shut-off valve, and a flexible connection hose, compatible with standard outdoor faucets in the US and Canada. Every installation accessory is included—no extra parts or tools required for setup.

• Multi-Purpose Cleaning for All Surfaces

  Gentle yet effective for car detailing, RV/boat maintenance, motorcycle washing, window cleaning, solar panel rinsing, and more. Safe for ceramic coatings, clear bras, gel coats, and glass, preventing mineral deposits that cause etching and dulling over time.
