CR Spotless DI-120 Simplest RV & Car Wash System, Spotless Rinse Works for All Vehicles, Motorcycles, Bikes, Boats, Planes, Yachts, Deionized Water System, Towel Drying Eliminated

Love this unit. Yes it is a little heavy. I keep it near the exit to my garage. It removes one step, wiping down the vehicle after a wash and the potential micro scratches that come with that process. I use it on two cars and a motorcycle. Makes drying the motorcycle especially easy as they have a lot of cracks, crevices and odd surfaces. I just rinse and let it dry. Perfect every time. Here is how I use mine to get the most out of it and make my car wash process easy. 1. I use a Flow Restrictor so it never goes past 2 gpm. With a flow restrictor on the inlet I can use any spray nozzle or soap foamer and not have to worry about the setting (this should be included in the package but oh well). I use this $10 flow restrictor: Neoperl 30 0640 5 3/4" PCA Garden Hose Adapter, Female 3/4" x Male 3/4", 2 GPM Maximum Flow Rate, Not Plated, Lilac Flow Regulator, Not for Drinking Water 2. I attach the kit's supplied washer hose to the inlet side with the restrictor installed. I keep this hose connected at all times. When I bring the filter outdoors I connect my water hose to this high quality hose. With that I don't have to keep reattaching to the plastic connector on the filter saving the life of that connector. 3. I use a Y-valve at the outlet. ( [[ASIN:B0183AQ4W SOMMERLAND A1001 Heavy Duty Brass Y 2 Way Garden Hose Connector 2-Way Splitter 10 Hose Washers]] ). One side I'll use to attach my soap foamer gun and the other I use for the rinse nozzle. Having these two attached I can soap an area, wipe and rinse. Then move onto the next area. With a soaper I'm not using a ton of water and it is mineral free. Soap foamer: Gilmour Foamaster II Cleaning Sprayer (95QGFMR) 4. I use 2 different colors of outlet hose so I can glance at a hose and know which has the foam gun at the end and which has the rinse nozzle as they may get tangled together. I use these hoses: HBlife 50 ft Heavy Duty Expandable Lawn Garden Water Hose with 8 Spray Pattern Nozzle with Triple Layer Latex Core & Latest Improved Extra Strength Fabric Protection and HBlife 50 ft Heavy Duty Expandable Lawn Garden Water Hose with 8 Spray Pattern Nozzle with Triple Layer Latex Core & Latest Improved Extra Strength Fabric Protection 5. When I'm all done I'll go over it one more time with the rinse nozzle being sure to really get the cracks and crevices. 6. If I'm going to drive that day I will wipe it down but most days I just pull the vehicle back into the garage and let it sit and dry. Absolutely no water spots!!! With this process I have greatly reduced my car wash time and the amount of water I use. Plus I never have a single water spot.

This system is a game changer for my car washes. Where I live there is *very* hard water. So that means if I walk away from the car for a second or *any* water dries I have really bad water spots. If you're shopping for this, you're probably like me and you like having a car without water spots. It's also nice to be able to take my time washing the car, and not have to waste extra water constantly wetting down the car. Some things to note about the DI-120. For the filter to work optimally you have to use a nozzle that is <= 2 gallons per minute (GPM) in flow rate. The filter comes with a small cheap nozzle supplied that you can run in either "Flat" or "Center." I however had planned to use this product with the Chemical Guys Foam Blaster 6. The FB6 doesn't come with any indication of water flow rate. At first I was googling around, but then remembered basic science and math. If you want to measure a particular nozzle's flow rate do the following. Mark off 2 gallons in your 5 gallon bucket. I did this by using the fact that 1 gallon = 16 cups. In my kitchen we have a 4 cup glass measuring cup. I just filled that up 8 times to fill my bucket with 2 gallons. I then used some duct tape to mark the water line at 2 gallons in my bucket. Some buckets might have lines, so then you wouldn't need to do this. Then I took my Foam Blaster 6, ran it fully open while timing it. Noted the time then do the following calculation flow rate = <gallons> / <time in minutes> to get the flow rate. This will work with any nozzle. So I finally hooked the product up to my hose which was easy. It comes fully assembled in the box. The directions are very clear. The water pressure out of the filter is great, the water coming out IS TOTALLY FILTERED. I literally had 0 water spots. I have to say the product is very sturdy, and well built. If you're on the fence about this, and like having spot free washes just buy the filter. It's worth it. One disclaimer is that I've used it only once, so I don't know how often I need to replace the resin in the filter cartridge. So that could change my opinion once I understand the overall running cost.

I have not been able to wash my vehicles at my home since I bought the house 15 years ago. The water is terrible and it not only leaves white spots, it leaves white streaks. I finally decided to see if there was something I could purchase specifically to treat the water for car washing purposes. I was hesitant to spend the money for this at first; seemed like it was pricey. But I decided I would chance it based on the reviews. I have not been disappointed! No spots, no streaks, regardless of whether I leave the vehicles to air dry or use a drying cloth. So far I've used for about 5-6 washes and have had no problems - the ppm meter still reads zero. I have a red BMW convertible and a white Toyota 4Runner. I use the water from the system to do the initial rinse and final rinse - following the directions I don't actually put very much water through the system. I will purchase replacement resin so that I have it on hand and while it may be a bit pricey, it's worth it to me. If I had taken the vehicles to the car wash, it would have cost me about $60-$70 for the 5-6 washes. And I now have the convenience of taking my time in my driveway rather than trying to plan when I can bucket wash in a public car wash stall.

Yep. It works. I was worried about how often I would have to change the resin (which is $40 per hit, I believe), but so far have been happy with how long this puppy is lasting. Here's how it works: There is a small digital readout near the top that will measure the resin and let's you know when it's time to be changed. It's a little confusing at first... Every time you turn the digital readout on it will read double-zeros ("00"). You would think it would start at 100 or 10 or whatever then work it's way down to zero...but that's not how it works. It's actually measuring the effectiveness of the resin...so as you use it the numbers will eventually change from "00" to 1, 2, 5, 15, etc... The instructions say once the number reaches "20" or more then it's time to change the resin. You can still use it, of course, but it will not be as effective at deionizing the water, thus leaving water spots behind on your vehicle. I live in Louisiana. We have hard water which other reviewers have stated will eat the life out of the resin. But I bought this thing about 10 months ago and have probably put 8 or 9 car washes on it (full-size F-150 super crew) so I use lots of water to "rinse" my truck after I wash it. And so far I'm still at double-00 on the readout! So if I can get about a year's use out of one canister of resin I would gladly pay $40 a year to not have to dry this beast of a truck. Worth every penny. Here's why I can't give it 5 stars.... 1. This thing is a PITA to move around. It's sneaky-heavy and awkward to carry because of the steel frame. Can't we get some wheels?? There is a $400 or $500 unit that has 2 canisters and a handle with a couple of nice, large wheels so you can move it around. For $250 bucks they need to put a handle and a pair of wheels on this thing so you don't pull a hammy moving this thing around the yard, good grief. 2. It comes with a cheapo water nozzle, which is all good and fine. But the instructions are adamant about making sure you DO NOT EXCEED A FLOW RATE OF 2 GALLONS PER MINUTE through your water hose. Then they tell you to use the nozzle that is included but only use it on the "Center" or "Flat" setting. I assume they hope that by giving you a $5 cheap nozzle and setting it to "Center" or "Flat" you will not have to worry about your water pressure exceeding 2 gpm. Well my friends, this is complete gobbleygook. You will need to purchase a FLOWMETER on Amazon. This will measure your GALLONS PER MINUTE (flow rate): http://www.amazon.com/gp/product/B00880R5OI/ref=oh_details_o07_s00_i00?ie=UTF8&psc=1 Super-simple to use and ready to hook up to your hoses so you can measure flow rate, or gpm. The GALLONS PER MINUTE issue is paramount to making sure you get the most bang for your buck out of your canister of resin. If water pressure is TOO HIGH then the resin will not work properly and you get water spots. Then you'll send the unit back and complain on Amazon that it doesn't work. It does work...IF you have the right tool to measure flow rate. But...they don't give you the tool to measure it??!! I have no idea why the makers of this product cannot include this as part of the system. To me it's a no-brainer. They could probably even wire it to the existing digital readout so you can test the unit, get the flow rate set, then get to washing and "drying" your car. The digital readout times out after a minute or two so you don't have to worry about leaving it on and draining the battery. How, you ask, can you set the flow rate?? Well, you just turn on the water at the spigot while holding the nozzle open full-blast (on the "Flat" setting which I find works best). Then you look at the flowmeter and turn the spigot slowly to the right or left until you see the dial inside the meter measure 2 gpm. Easy breezy nice and cheesy.

I read up on this and bought it for the express purpose of not having to hand dry my cars after washing. Not just to save the effort but to avoid the scratches drying causes. I have to say that this filter absolutely does what it claims. I could hardly believe that it could work but my cars dry without a spot on them, even the glass. I will offer this advice about this filter: READ AND FOLLOW THE DIRECTIONS!! It isn't rocket science. Just please take the time to learn how it works and you will be rewarded. Some reviewers have complained of setting the flow rate. Simply time how long it takes to fill a gallon jug. If it is 30 seconds or within a couple of seconds either way you are at 2 GPM. Easy! Then just use that water for your wash bucket, no reason to waste it! Mine came completely assembled except for the inlet hose. I did have to tighten the canister as it leaked slightly from the top the first time it was used. No other issues with the filter. I wondered, as many other reviewers have, how long the filter might last. This was actually very easy to determine. If you go to the manufacturer website there is a chart that answers this question. The filter life is a direct result of how much material it must remove from the water. In my case I went to the website for my city and looked up the water quality reports. This will show the quantity of TDS (Total Dissolved Solids) in the water. Then just compare that number with the chart on the CR website. Find it under the FAQ. In my case the TDS is 150 so the unit I have will process about 259 gallons. I use about 8 gallons to wash my car so that's 30+ washes with no hand drying of the car! Sweet! Since you are already looking at the CR Spotless website make sure to check out the resin recycle program. The resin and cartridge are recyclable. They even ship it for free and provide a return label for the old one all for a very reasonable. So if you are on the fence about a CR Spotless unit I would recommend checking the TDS in your water supply first. If it had been really high in my water I would not have bought a deionizing filter. I am pleased with it. Period.
