AQUATICLIFE Aquatic Life Deionized Spot-Free Car Rinse Unit - Premium Water Deionizer for Car Washing - Spotless Car, RV, and Motorcycle Wash System

Cleaner than clean

I've had a pressure washer hooked up in my garage for years. When I go to wash vehicles it's always ready, just hit the button and blast. And then when I got introduced to using a deionized rinse I saw life getting even easier by eliminating the most "work intensive" step...the drying! I wanted something just as simple but also effective, something I can get several uses from before having to recharge, not take up a lot of space and something that I could recharge using bulk resin because I hate the idea of buying throw away canisters and paying 4 or 5 times as much for the material which is already expensive. Also, I wanted it to be easy to see how my resin is holding up. This unit accomplishes all of that. I can recharge the existing canisters keeping costs down, one glance and I can see how resin is holding up and the whole thing mounts on the wall and takes up minimal space. And all that for under a hundred bucks (and about $25 in PVC)! So far I've washed my truck about 3 times and my car twice and used maybe 3/4" of resin. I don't know how my water rates for contaminates (I'm on town water) but I can say it looks like I'm going to at least get the entire season out of this before having to refill the canisters. And it does work just like they say, after washing and rinsing a vehicle I just give it one last rinse with the DI water and walk away. It actually dries more spotless than using a chammy which still can leave streaks. One cloudy day (about all we get here in upstate NY lately!) my truck sat in the garage and took over a day to finally dry, yet, not one single water spot!Update: It's been a year now and I can report, as I was hoping, the canisters did - albeit barely - last the entire season! My bag of resin came in last week, I'm about to refill them for this season. Looks like I'll get several refills (seasons) out of this $60 bag. For what I have invested this has been a most worthwhile acquisition, love the way this works!

A company that makes RODI units for fish tanks should know that just using a DI filter is not enough to remove all TDS from water and maintain a flow rate capable of drenching a car. I should have know this too. Adding an ro filter will not provide enough pressure to spray a car, so this device is simply a way to consume DI resin with "spotty" results while wasting your time and money. Here are 2 solutions as I see it.1. Get a true RODI filter unit and have it fill a 55 gal plastic drum with an auto shut off valve. Then use a pump, hose and nozzle to spray your car with true RODI water. Let it fill back up ready for the next wash. Depending on the filter setup it could take 48 hours to get 55 gallons of RODI water and you will burn through filters. Or...2. Wash your car, and use Meguires (or equivalent) hybrid ceramic wax to finish the wash. This creates a hydrophobic coating where water easily sheds off of the surface just like rainx. Using just plain hose water is fine. Then, for the final step us an electric leaf blower to blow the water off your car. Be careful not to fry yourself by letting the cord sit in a puddle of water (battery blower is best). It works very quickly and effectively. You will remove 99% of the water. Use a drying cloth, chamois, or microfiber to get the remaining water off, and boom! You have a completely spot free car finish and you don't have any expensive consumables to replace.Hope this helps my fellow car enthusiasts!!!

BEFORE BUYING, read the reviews and questions. Know what you are getting so you can level your expectation.I was a bit skeptical and was about to purchase a more expensive spotless system that cost 3 times as much, but figured i'll give this a shot anyways. It WORKS and the feeling of not having to quickly run to the sunny side of my car to dry before it leaves spots, is amazing.Before buying this, I read that 1) the water flow is slow so you need to get a specific hose nozzle and be willing to deal with a slow rinse 2) you DO NOT use this for the whole wash, only the final rinse, and 3) depending on how bad your water is, the resin can go by very fast. Because i expected these and were willing to deal with the outcome, i was very satisfied with the unit.I do not have the nice setups with shut off valves like some of these reviews as i wanted to test this before mounting. Only thing i use is a valve splitter to run a separate hose, and purchased one of the hose nozzles recommended from Aquaticlife (i watched their video on the product page). Water pressure is low but with the nozzle, it works.I have the unit hooked up to my home water softer so i already have pretty decent water, but it still leaves small calcium (i'm assuming its calcium) spots. After installing the unit, i left 1 panel to dry by itself. No spots at all. Also only a small amount of my resin changed color after 2 washes (SUV and sports car), but again, i'm already softening the water. I suspect if i hooked this up to the water spout on the side of my house, the resin would go way faster.
