Review: Excellent DIY Car Wash Filter - Don’t know why a bunch of people have issues with this kit. I have rigged it up to fit my need and this filter works amazing. No more water spots on vehicles. The filter or its attachments do not leak. I’ve gotten used to how much water to send through the filters now. I get about 3-4 washes per filter. Less if it’s a large vehicle. For a DIY setup, this thing works amazing.
Review: Works perfect! Exactly what I wanted to accomplish. - 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!

## Questions & Answers

**Q: Where can I get resin and what do I buy?**
A: Lots of places sell it in raw form which is by far the cheapest way to go as "the stuff ain't cheap"! Do an internet search for DI resin and you'll find several vendors. Some sell a whole cubic foot and it's $200-300 or so and will refill this kit numerous times, probably more than you need so look for a deal on like 1/4 or 1/2 cubic foot which should hold you for a couple years. You'll need the "mixed bed resin".

**Q: filtered pressure very low, removed regulator and better now, is that ok? plus I believe inlet fitting bad cause cannot stop the leak?**
A: The Spot Free Car Rinse works because the mixed bed resin removes the Total Dissolved Solids (TDS) in the water. TDS is things like calcium, that leaves spots when the water dries. For the resin to remove the TDS, the water must flow slow through the resin. If you remove the Flow Regulator, the resin will not absorb all of the TDS and you will still have spots on your vehicle. You need to keep the Flow Regulator installed. Regarding the leak, do you mean where your garden hose attaches to the unit? If so, we suggest trying some Teflon tape to stop any water from leaking.

**Q: Does the water flow through the cartridges simultaneously or in series?**
A: The water flows through the cartridges in series to allow more time for the water to interact with the mixed bed resin.

**Q: Can this be used as a hard water filter for my dishwasher?**
A: No. Use an inline water filter for a refrigerator ice maker for that purpose.

### ⭐⭐⭐⭐ It works as advertise as long as you are willing to deal with some (well documented) negatives
*by K***N on March 19, 2021*

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.
