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-20 comes complete with 2 20 inch wall mounted cartridges containing a mixed bed of de-ionizing resin that will produce approximately 200 gallons of mineral-free water based on an average TDS level of 200 ppm. Depending on the quality of the water where you live, you can get between 75 and 1000 gallons of deionized water from one resin cartridge. All CR Spotless Water Systems also include a battery operated TDS meter that will measure the quality of the water coming out of the system. Includes two 20-inch wall mounted de-ionizing resin cartridges, Stainless Steel input Line, filter wrench, Spray nozzle, and battery operated water Purity Indicator - 1 Year Review: Pricey but it works! - Not sure how many washes I'm gonna a get out of this before I need to replace the filters, but seeing as I only use it for the final quick rinse, it should last a few months from what I've heard. Foamed, cleaned and rinsed my car. Then ran the water thru spotless for the final quick rinse. Left the car out in the Florida sun without drying it. It dried to perfection. Not a single water spot Not even on my windows which I always have to come behind and clean to wipe away the hard water spots. Great product. Man I hope these filters last a while because I would hate to have to spend $100+ a month exchanging them. Great product!! Review: Highly recommend if you want spot free washes! - This exceeded my expectations. I have a black car that I was always chasing water runs on and that is no longer an issue. My PPM went from about 160 to 0. I no longer have to spend so much time drying. I truly get a spot free rinse now. Would absolutely recommend. ## Features - Hard water spots can destroy your vehicle’s finish, reduce efficiency with solar panels, and create a dirty appearance on windows. We know.

Foamed, cleaned and rinsed my car. Then ran the water thru spotless for the final quick rinse. Left the car out in the Florida sun without drying it. It dried to perfection. Not a single water spot Not even on my windows which I always have to come behind and clean to wipe away the hard water spots. Great product. Man I hope these filters last a while because I would hate to have to spend $100+ a month exchanging them. Great product!! ### ⭐⭐⭐⭐⭐ Highly recommend if you want spot free washes! *by B***N on December 8, 2025* This exceeded my expectations. I have a black car that I was always chasing water runs on and that is no longer an issue. My PPM went from about 160 to 0. I no longer have to spend so much time drying. I truly get a spot free rinse now. Would absolutely recommend. ### ⭐⭐⭐⭐⭐ Never Washing a Vehicle Without It *by Z***B on March 19, 2023* Expensive, yes. Expensive to maintain, yes. However, this is a very well made product and works as it should. I use it purely as a spot free rinse with the included hose end sprayer. This takes all the stress of trying to hurry up and clean then dry a vehicle away. Likewise, trying to deal with annoying hard water spots is now a thing of the past. I have very hard water (350-400 tds) and so far I’m at 4 rinses on an average sized SUV with the meter still reading 0 tds. Mounted this to a 2x4 with sufficient width to then screw it into studs which are 16” on center. ## Frequently Bought Together - Spotless Water Systems - DIW-20, Simple Window, Solar Panel, RV & Car Wash System, Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Towel Drying Eliminated - GESHATEN 3/4” GHT Male x 3/4” NPT Male Connector, Brass Garden Hose Fitting, Adapter, Industrial Metal Brass Garden Hose to Pipe Fittings Connect (2 Pack) - GESHATEN 3/4” GHT Female x 3/4” NPT Male Connector, GHT to NPT Adapter Brass Fitting, Garden Hose Adapter, Industrial Metal Brass Garden Hose to Pipe Fittings Connect (2 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/642493601-spotless-water-systems-diw-20-simple-window-solar-panel-rv](https://www.desertcart.no/products/642493601-spotless-water-systems-diw-20-simple-window-solar-panel-rv) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
