Do you have hard water spots on your vehicle? Adam’s Polishes in collaboration with On The Go, an American Business, has developed a small compact deionizer unit to provide a large supply of laboratory grade deionized water for a spot free water.

This feature will ensure that you get the optimum life span from each bottle.

My first experience with a deionizer...a game changer for me. All three of my cars are ceramic coated and between this device and your power washer I can count on not having any spots forming on my cars, all of which happen to be black. It is especially important since I use a leaf blower to get rid of most the water but leave just enough to facilitate the use of a ceramic rejuvenator product. So the left behind water does not spot before I have a chance to remove it as I apply the rejuvenator. For me the set up is a win-win!

amazing excellent work

After 2 months of research I decided on Adam's brand. I am very satisfied so far. I hope it has durability and looks good quality. My house had 252 dissolved solids and measured 0. I bought this product because of the integrated keys that will facilitate the durability of the replacement. Highly recommended. Yes.

NO SPOTS if you air dry!

Maybe I am just being picky but IMHO these should come with better connections. I'm not a fan of plastic and on the 'pro' or top end model, I believe they could be better

*10lb Resin Refill Is Recommended For Basic Unit

*20lb Resin Refill Is Recommended For Standard Unit

*40lb Resin Refill Is Recommended For Pro Unit

First Time Hook Up Instructions

Step 1: Lube up all four O-rings on the red bypass valve assembly and 90° gray elbows.

Step 2: Screw both sides of the red valve assembly tightly on to the black head.

Step 3: Connect both of the 90° gray elbows tightly to the red bypass valve assembly.

Inlet(female garden hose thread): Downflow Inlet stamped on black head/left side unit facing you

Outlet (male garden hose thread): Upflow Inlet stamped on black head/right side unit facing you

Step 4: Connect source water to inlet and flush the system out for 2-3 minutes.

Step 5: Your unit is ready for use.

Refill Kit Instructions: 

Step 1: Turn off the water supply and remove the red bypass valve assembly from the black head.

Step 2: Remove the black head and empty the used resin into a waste container.

  • Resin is environmentally safe and can be disposed in accordance with federal, state, and local regulations.
  • Distributor tube and basket will be removed during this procedure.
  • The basket on the bottom of the black head can be unclipped to lube the O-ring that is inside the head.

Step 3: Rinse out any of the remaining resin from the tank with water.

Step 4: Return distributor tube into the tank, slip/place rubber cap into top of tube and then place funnel into top of the tank. 

Step 5: Slowly pour or scoop resin into the tank. Shake or tap tank to get all of the resin bedded.

Step 6: Remove funnel and rubber cap. 

Step 7: Make sure all O-rings are properly seated and lubed (lube provided).

Step 8: Make sure the top basket is clipped into the black head. The top basket will slide over the distribution tube and slip into the black head when you push it down and screw it on.

Step 9: Screw both sides of the red valve assembly tightly on to the black head.

Step 10: Turn on the water supply and flush the system out for 1-2 minutes. During this process you are flushing out the resin dust from the virgin resin.

Step 11: Your unit is ready for use.



-How many gallons will the standard unit produce?

The capacity of a deionization systems is primarily determined by the Total Dissolved Solids (TDS) in the water source. The TDS can be measured by using the meter provided. The TDS can range from 0 to 1,000 PPM plus but typically will fall between 100-400 ppm across the US.

Example: @ 100 ppm of TDS = 1,120 gallons

- What value of PPM will leave my vehicle with a spot free rinse?

We have provided these ranges over the years:

Excellent level: less than 15 ppm

*Satisfactory range: Greater than 15 ppm but less than 50 ppm

Unsatisfactory level: Greater than 50 ppm

*Depends on coloration of vehicle, degree of stainless and one’s individual acceptance level

 - Does this reduce my water pressure?

There is a small pressure drop and should not be noticeable.

- When should I replace the resin in the tank?

An acceptable TDS ceiling will vary from customer to customer and is greatly dependent upon the coloration of the vehicle. Most customers will operate between 20-40 ppm of TDS, mid-thirties seems to be a fairly wide acceptance level.  We would recommend the use of the rather accurate digital TDS meter and measure the TDS during your first cycle thus quantitatively obtaining your preferred level.

- Is it safe to drink?

We do not recommend drinking the water.

  1. DI water has all the nutritional value removed
  2. DI has an operating cost generally higher than drinking water
  3. DI tends to have a unique taste and odor

- Can I water my plants with Di water?

You really don’t need purified water for your plants thus we would not recommend.

- Can I run heated water through the Di tank?

The DI has a max temperature of 105 degrees Fahrenheit.

- Can I hook my pressure washer up to the outlet of this Di unit?

Yes, ensure the flow rate of the HPW is within the optimum operating range [0.5-2.5 gpm] of the DI unit and never greater than maximum of 3 gpm for best performance.

- Should I use Di water for my entire car wash?

 You can, but many will use only for the final rinse.  

- How does a Deionizer work?

“Deionized Water”-Simply said, water flows over porous beads that are positively and negatively charged and the minerals or total dissolved solids are removed. These ion exchange columns are porous beads called exchange resins producing laboratory grade water.

- Will this harm my paint on my vehicle?

No, DI water used to obtain a spot-free rinse has been used for applications including Auto’s/Class A RV’s/Small airplanes/Motorcycle’s/both residential & business windows plus many car washing businesses use this for their final rinse.  

- How long is the Tank good for if not used?

The resin has a shelf life of 18 to 24 months.

- What do I do with the used resin once I refill the tank?

The resin is non-hazardous and can be disposed through normal waste disposal processes. Always dispose in accordance with federal, state and local regulations.

- Can I use this with Adam's Soaps?


- Is DI water safe to go down a drain?
