It is just as advertised totally satisfied

Used as a quick detailer. Two coats.

Full disclosure: as far as Korean-made auto detailing products go, Im normally a Gyeon fan. Their product lineup and design approach typically hits my needs better than Carpro (though both companies make excellent products), and the support from the Gyeon USA office is unbeatable. But its 2021 and Gyeon STILL hasnt developed a waterless/rinseless wash, so Carpro ECH2O it was. On paper ECH2O sounds great, being usable at a variety of dilutions for purposes from clay lube to quick detailer to waterless wash to rinseless wash, and even claiming seemingly-insane things like works great even in direct sun. Living in sunny Phoenix, I didnt have much faith in that last bit. But... in practice ECH2O works great, being usable at a variety of dilutions for purposes from clay lube to quick detailer to waterless wash to rinseless wash, and even when doing seemingly-insane things like waterless washing in direct sun. Seriously. I set out to torture test it as a waterless wash in the midday Arizona sun, and… it worked. Perfectly. It still stayed moist long enough to work your section, it still suspended the dirt to prevent paint damage, and it still left behind a beautiful, slick gloss after the final wipe. Ive only got two minor gripes: 1. At most dilutions, it leaves plastic trim panels too glossy for my taste. You can knock this down with a clean microfiber after your final wipe (or by continuing on with a trim detail), but be aware your trim will look dressed anywhere youve used it or wiped up runs and overspray. This is less pronounced if youre diluting to rinseless wash dilutions. 2. ECH2O really likes to hide in nooks and crannies; even moreso than other quick detailers or waterless washes. This will be less of an issue if your vehicle is ceramic coated or recently sealed/waxed, but be prepared to shove the edges of your microfiber into panel gaps to wick out product playing peek-a-boo.

Highly recommend.

Can be used in between washes.....doesnt do well with chrome, will temporarily stain or tint it. If rain hits it a day or two after it will leave little water marks. Does leave a nice gloss after applied.

I use nothing but carpro products there a little pricey but worth every cent I used ECH20 for the first time gitta say this is by far one of there best product used it as a waterless wash the results are amazing and the bottle goes a long way cause it gets diluted HIGHLY RECOMMEND…

Awesome will be my new car products

Works really well as a detail spray. Sprays out a fine mist that is easy to wipe off.

Great emulsifying properties for such a low concentration of product to water. It’s also a great value because of how much you can dilute it. In Southern California we have a lot of water usage restrictions so this is a great product to have in my arsenal.

Fabuloso
