Review: Not for well water!! - I bought this to use on my black Escalade I wash my truck and sports car 1 time each and then washed the truck a second time with this system a week later and the meter read 9.2 when I started but I forgot to check it while washing and it went to 92 which I didn’t notice till I was done didn’t think that only after 2 uses that it would read over what’s recommended let alone 92. We have well water with a chlorinator, which means our system, uses bleach with a filter. So very similar to city water after washing my truck next day I go in the garage and I realize there are these horrible white spots that even with an exterior detail spray will not wipe off. Unfortunately, I had to pay a detail company, the buff and polish my truck, because the system failed only after two uses.
Review: Water Spots Everywhere!!! - I bought this filter to rinse dust off my boat in between washes and now it's completely covered in water spots. The boat was detailed a few weeks prior to this rinse and it's kept in a covered slip. I contacted the company through their site but they never replied but they might after reading this review. Worthless product and even worse service.

## Features

- Hard water spots can destroy your vehicle’s finish, reduce efficiency with solar panels, and create a dirty appearance on windows. We know. That’s why we created a de-ionizing system that takes out all of the minerals in your water so you can just WASH, RINSE, and WALK AWAY!
- With a CR Spotless Water System, you can let your car air dry and not leave any spots behind. Besides cars, de-ionized water is perfect for washing and SPOT-FREE rinsing of your RV, boat, golf cart, motorcycle, and house windows, too! De-ionized water is the secret sauce that detailers, car washes, and window cleaners have used for decades.
- CR Spotless was the first to make the same technology available to homeowners in an affordable, compact, and portable system. Work smarter, not harder and spend less time and money to get the same professional looking results.
- The DIW-10 provides approximately 150 gallons of mineral-free, de-ionized water based on your water input quality. It consists of two 10 inch de-ionization housings that feature replaceable (or refillable) cartridges that simply slide into the watertight tubes.
- The entire unit is mounted on a powder coated, rust resistant wall mount that makes it convenient to mount in your desired location. Ships with all the parts and accessories needed to start rocking and rolling with all the spare time created by your CR Spotless deionized water system.

### ⭐⭐⭐⭐⭐ This is amazing!
*by F***O on May 3, 2022*

I have been looking into CR Spotless for a while. I live in Texas, and we have very hard water. DIW-10 is awesome if you don't want something bulky in your garage (I used it next to my pressure washer for a while until I could mount it properly, it's heavy enough to stay up). What I would recommend is using a 1.2 GPM pressure washer connected to it, and the filter will last a long time. You can use online calculators on their website to figure out how much. I would also say, don't listen to comments that your car can dry in the sun with this - it can, but the pre-wash and soap scum will also dry very fast. You only want to use it for rinsing after you're all done. I have a Tesla Model 3 with ceramic coating, and after rinsing with this all I need to do is wait for the car to dry out - no more water spots.
