Best waterless wash and drying aid
January 4, 2021
Very versatile waterless wash, QD and drying aid.. I mostly use it at 1:20 - 1:25 ratio.. Its very very slick and leaves a really good glossy finish. Also works great for mixing other water based products into it (e.g. carpro reload, sonax BSD etc) and it still works great as a QD ..
ProsDilution, ease of use, value for money
ConsIf the prepared mix is kept for long in bottle, it begins to stink like rotten rat.. Observed the same with Perl diluted mix too.. But I am talking about several 5-6 months here.. So prepare only the mix you need. Dont just prepare gallons that you wont be consuming quickly.

Convenient hose-less cleaning
September 17, 2020
I am at a try-them-all point in my detailing career. I have used a few other brands of rinseless wash products. I like CarPro‚€™s ECH2O for: -dilution ratio, a little goes a long way -makes an excellent value -transportable washing, keep bottle in car -SiO2 protection on the go -cleans/washes easily, removes contamination -fun to use!
ProsValue Ease of use Dilute-ability Doesn't smell bad Leaves a nice gloss
ConsPerhaps it may streak? Be sure and wipe with one towel. Follow up with a second one.

BEST RW on the market, PERIOD! Works as well as a WW too!
August 4, 2019
I've been using and enjoying this product since it came out, it's simply THE BEST RW on the market, PERIOD! I use 2 ounces for about 3.5 gallons of water. This allows me extra solution for pre-treating the panels. I throw about 5 plush, edgeless mf towels in the solution and it not only cleans well but the Gloss left behind is undeniable! As far as using it for WW duties it's also great but dilution ratios are VERY important. IMO 7:1-10:1 is the range but even @7:1 some buffing is to be expected BUT once again, the Gloss left behind, is INCREDIBLE! I've been on AG since Feb of 2012 and have used/tried/tested over a dozen RW and WW's and if you want 1 product that does both, works in conjunction with coated and non-coated cars, THIS IS IT!
Pros-Cleans great -High Gloss -Noticeable protection left behind -Use it knowing it's the best in the world!
Cons-Not having used it before, your missing out

Perfect for coatings
June 27, 2018
Works great as a waterless wash to clean and maintain my coated cars. An added bonus is the gloss added to your coated vehicle. A must have for any coated vehicle.

So far so good. I have used it 3 times so far and it does a great job after a little buffing once it is dried. I will have to try it in the winter month's to see how it does then. I think it has the best shine of all the products i have tried to date. I have tried both rinse less and water less and both times results were great.
ProsCleans well so far and the shine is amazing.
ConsNeeds a little work during the drying stage but well worth it.

ProsShine, Very economical (dilution ratio) practical many uses

Amazing and affordable
March 31, 2018
I was just amazed of the gloss of this product after application, took me 20 min to waterless wash my Porsche and looks like I washed the car and applied carnauba wax which all could take you hours, the smell of the product is very pleasant, the liquid is thick and very slick and the best part is that leaves your pain with Si02 protection a plus over your Si02 coating. I calculated per wash it is just 1.8 dollars per wash! Yes it is very affordable and leaves a slick and amazing gloss. Need to try to understand.

I use it as a detail spray
December 6, 2017
Although this product is made for waterless/rinseless washes, I use it to make my quick detail spray. I add 2oz of Ech2O, 2oz of CarPro Reload, and fill the rest of a 32oz bottle with distilled water. That makes a great detail spray for a ceramic coated car.

Your Search Is Over!
January 2, 2017
There's a lot of waterless/rinseless wash products out there and I'm here to say your search for the best one is over! After using this as a waterless wash, detailer, and rinseless wash I'm happy to say my search as well as yours is over and I couldn't be happier. Previously I've used Chemical Guys waterless wash, Ultima waterless wash +, Meguiar's rinseless express wash, and now have had the pleasure of using CarPro ECH2O. Of all of them, ECH2O has the highest lubricity, is the slickest, easiest to dry and buff off, removes dirt the best, and leaves the slickest and most glossy finish. Most other rinseless wash products either were slick when wet and became sticky/gummy when buffing dry or they had a low lubricity when wet but were at least slick when drying. Not ECH2O, slick all the way. Had problems with streaks on glass? Not with ECH2O! Worried about hindering the hydrophobic properties of your expensive coating with polymer waxes left behind by other rinseless washes? Not the case with ECH2O! But it's a bit more expensive than some of the other rinseless wash products on the market. Well, when you break it down to the numbers, ECH2O is quite cheap. 1L makes 52 gallons of rinseless wash. I promise you 1 gallon is plenty to do a wash on even a large vehicle. So even if you mix up 3-4 gallons at a time, you'll get 3-4 washes out of it. 52 washes for a retail price of $25 is approximately 50 cents per wash! 52 washes with 52 weeks in a year, you could wash every single weekend and this one bottle will last a whole year! Either way you figure it, $25 a year (more realistically 2 years as hardly anyone washes every weekend), or 50 cents a wash, it's not burning a hole in your pocket, but the shine it leaves just might burn your eyes if you stare too long. FYI - Mix up a bottle at quick detail dilution (1:20) then add 2 oz. of Reload for a perfect maintainer of your coating's hydrophobic properties.
ProsExcellent cleaning Super Slick Easy wipe off Very versitile
ConsNone other than if you end up washing your car too often because this stuff is so easy and fun to use
