What is de-ionized water from a CR Spotless® proprietary system?

Deionization is a method used most often by laboratories to produce purified water on demand. All naturally-occurring water contains dissolved mineral salts. In solution, salts separate into positively-charged cations and negatively-charged anions. Deionization can reduce the amounts of these ions to very low levels through the process of ion exchange. Cations are removed by cation exchange resin. It replaces sodium, calcium, magnesium, and other cations with hydrogen ions (H+). This exchange produces acids which must be removed or neutralized by anion exchange resin. This is also why you must not use the system outside of its operating parameters or you could cause damage to your work surface.

Two general types of anion resin are used for deionization: weak base resin and strong base resin. Weak base resin adsorbs strong acids, while strong base resin exchanges chloride, sulfate and alkaline anions for hydroxide ions (OH-). The hydrogen ions from the cation exchange process combine with the hydroxide ions from the anion exchange process to form water (HOH or H2O). Because the deionization process is so effective, the water quality is usually measured by the water’s resistance to electric current (in OHM-cm). The end result is purified water that won’t leave mineral deposits – water spots – on your car! The bottom line is that the CR Spotless proprietary system is a blend of filtration and deionization which gets the best results in the industry- ZERO parts per million total dissolved solids.

How does it work?

As the water passes through the filter(s), all the spot causing calciums and minerals in the water cling to the resin beads and the purified water continues on to provide spot free water.

Will soft water extend the life of my resin?

Softened water (potassium or sodium based) will not extend the life of the resin. The TDS count of the water coming out of the water softener will be (more or less) the same as the water going into your softener and may damage your work surface in cases with high levels of total dissolved solids in the supply water.

When do I need to change the resin?

We recommend replacing the filters when the TDS meter reads above 0 ppm.

Deionized water systems produce 0 ppm water which is physically impossible to leave any spot-inducing residues on your work surface. Filter expiration characteristics are primarily dependent on your local water quality (higher flow rates/resin age can also contribute) and may produce work surface damage above 0 ppm. Nearly every one of our customers do not experience any spots/damage between 1-10 ppm and the vast majority of our customers do not experience spots/damage between 10-20 ppm.

  • Use above 0 ppm may cause damage to your work surface.
  • You must test your system above 0 ppm with your local source on a test surface to determine your system’s expiration characteristics (i.e. when it starts to leave spots that must be removed by polish).

Will this unit work with well water?

Some well water users have experienced adverse results when using the system downstream of iron removers and/or water softeners. It is best to use the system with your well water before it passes through any stripper/softener and do not use if the CR Spotless unit TDS meter reads any number above 0 (typical resin life exhibits 000 ppm through approximately 90{96e7edebe559d7494a0aaa7e8ded1f6abdf749a6241d3cc50fac29d61a879e0a} of resin life so very little capability is lost by this protocol).

Will it remove my wax?

 No, it will not remove your wax and the best part is that you do not have to worry about tiny scratches cause by drying with a towel or chamois!

I referred a friend... What's in it for us?

First off, a top-shelf *thank you* for spreading the word about all things spotless!

The good news is that we gladly reward both of you each with $25 CR Spotless digital dollars (store credit) good for future purchases on crspotless.com 🙂

There are just a few things we ask for in order to make this possible:

1. The buyer must call us directly and ask for the reward pricing at time of purchase AND the referrer’s account/email info MUST BE IN OUR SYSTEM! To be in our system means you purchased the unit directly from us OR registered the product on our website Product Registration link (at the bottom of every page).

2. You will receive an emailed $25 CR Spotless website code after the 30 day return period has expired. You must enter the code in the coupon code field at checkout on your next purchase. Spotless dollars (store credit) may be applied to any item and is not redeemable for cash.

Will the resin go bad if I let my system sit for a long time between uses?

Yes, it is possible. After long periods of non-use there is a possibility that algae can form and foul the resin. If it is going to sit for a long period of time with out use (60-90 days) we suggest that you remove the resin cartridges, allow them to drip dry and dry the inside of the blue housings to prevent algae growth.

Do I need to use a special soap?

To achieve the most stellar shine, we recommend using Simple Chuck’s Suds ‘N Shine soap (the only soap designed to be used in direct sunlight!). But no, you don’t need to use a special soap to achieve spotless results using our systems. Just use your normal soap and make sure you rinse thoroughly wherever soapy water can be trapped. Be mindful of soapy or contaminated water that can get trapped in places and displaced by our *spot-free* water, only to land on a spot you’ve already rinsed! You’ll quickly learn where this ‘bad’ water lives as nothing with rat you out faster than water that cannot spot 😉

Can I recycle my resin?

You sure can! Simply order a filter exchange and we’ll send you fresh cartridges filled with resin. You simple place the spent cartridges in the bags provided, attach the pre-paid shipping labels, and return within 4 weeks of receipt of the fresh set. Along with another 9,999 spotless recyclers, we’ll save 72 TONS of plastic from the landfill for each exchange!.

Can I drink the water?

No, please do not drink the water. Deionized water produced by our system is not meant for human consumption and has no nutritional value.

Can I hard plumb it into my house?

No, it can harm some of your interior household plumbing.

The system is all hooked up but no water is coming out?

You have placed one of the cartridges in upside down. The white, screw-on cap belongs at the bottom of the blue filter housing and the black rubber washer belongs at the top, mating with the housing assembly.

How much water pressure is OK?

The blue cartridge housings are rated at 90psi maximum and the unit is leak-tested to handle this amount of pressure. Typical residential regulators reduce pressure to 65psi and both your Spotless Water unit (and your house) may be in jeopardy if operated above 90psi.

The meter reads “Err”

The wiring harness that plugs into the meter has become unseated. Remove the meter off its velcro mount and gently remove and reseat the wiring harness. Be careful not to tug on any one wire to do so. Grasp the entire harness assembly at once when removing and reseating. If ERR remains, please contact us.

Does the resin have a shelf life?

Yes, the resin has a shelf life of approximately 12 months before it will start to lose effectiveness.

How do I store the system?

If you are not going to use the system for a couple of months please drain the water out of the system and let the resin cartridges drip dry. Reinstall the cartridges and connect the provided stainless steel hose to both the inlet and outlet ports (this seals the system and prevents moisture escape).

I just used my system for the first time and I have spots? #disappointed

Rats! We hate it when that happens…it’s why we created the system in the first place! Assuming those spots weren’t already there (ahem…our system only keeps them from forming; it does not remove them), this could be due to a few issues.

The primary causal factor is letting the work surface dry outdoors when ‘stuff’ is floating in the air and lands on the drying water causing a ‘dust ring’. Airborne pollen and neighbors with yard blowers are the bane of *spotless* existence so keep an eye (and ear!) out for these contaminant sources.

Another causal factor could be that the output hose you’re using is old…and probably a 50 footer. Over time, hoses will absorb minerals and the first thing deionized water wants to do is collect ’em up and (unfortunately) carry them out the business end of the hose and onto your work surface. As long as your meter is reading 0, the only thing coming out the business end of the system is hydrogen & oxygen so be sure you’re not donating any unnecessary minerals to your spot-free water. A new hose should solve the problem.

Another reason may be that you’re rinsing away pockets of soapy water and some of that is getting bounced onto areas you’ve already rinsed off. Don’t use more water than you have to, but it is necessary to remove all soapy and/or ‘dirty’ water to enjoy the *spot-free* capability we designed into the system.

Can I use a pressure washer with my deionized water system?

Absolutely! In fact, it can be the easiest way to cut your resin use by 75{96e7edebe559d7494a0aaa7e8ded1f6abdf749a6241d3cc50fac29d61a879e0a} (wow…did we just say that?). Yes- we did because a) we don’t want you to unnecessarily waste product (and water) and b) we’ve been enjoying pressure washers with our system for over a decade and learned a few things as a result.

The primary contributor to resin (and, more importantly, water in the draught-savaged region of the West) consumption is the amount of water you flow through the system in a given amount of time (hence gallons per minute or GPM). The nozzle we supply with the system uses about 2 GPM of water with standard residential water pressure and now there are many electric pressure washers that only use 1.2 gpm. We like cocktail napkin math so let’s call that a 50{96e7edebe559d7494a0aaa7e8ded1f6abdf749a6241d3cc50fac29d61a879e0a} reduction in water for the same amount of ‘spraying time’.

The second order effect of a pressure washer is that it is easily twice as effective as a spray nozzle: a pressure washer ‘blasts’ contaminants away while a nozzle ‘sprays’ it off. So instead of spraying the nozzle 4 or 5 times across the hood, just blast it twice with a pressure washer and Viola! you’ve accomplished the same task by using 75{96e7edebe559d7494a0aaa7e8ded1f6abdf749a6241d3cc50fac29d61a879e0a} less water (and resin). That saves $$$ and precious resources for a win-win all around.

How do I maintain my new Kranzle pressure washer?

Proper care of the newest addition to your cleaning arsenal will provide years of pleasurable return on your investment. It simply is the best pressure washer available!

  • Always be sure to inspect the oil level port before use. The oil level should never fall below ½ of sight glass and must be changed if it ever appears milky (oil/water contamination).
  • Kranzle recommends an oil change (.25 liter of 5/50 synthetic motor oil) after first 50 hrs of use. Afterwards, the oil will be good for life of unit.
  • While the Kranzle has the finest quality brass available in the pump assembly, you should always run ‘regular’ water through the system before storage to ensure maximum life from the pump assembly.

Can I lay my water system unit down to transport it?

Not without proper prep…you must first ‘Drain then Drive’. Laying down a system filled with water can disturb the resin bed inside the cartridges and allow bad water to bypass treatment. If you need to lay the unit down for transport, you should drain the water out of the cartridges by removing the blue housings, pouring out the water and allowing the cartridges to ‘drip-dry’ (standing on end with the white cap down) for about 15 min. Re-install and then get your drive on. Remember, Drain & Drive…

How many times can I wash my car before I have to change the filters?

CLICK HERE to view a simple chart that will show how many gallons our systems will treat depending upon your inbound water quality (as defined by parts per million of total dissolved solids) before you must change the resin or risk damage to the work surface. The hardest questions we get asked is how many washes you’ll get and that is best answered by how many gallons our system will provide. We then use this information to determine your needs (some folks use Niagra falls to wash their stuff while others measure the water by atomic weight and dispense accordingly…give us a call and we can help you figure this part out!).
