This has got to be my absolute favorite item in my rather large detailing arsenal. When uses properly it cleans flawlessly and leaves behind a magnificent shine. When used as a quick detailer for final inspection it removes dried up water spots and other flaws left behind from washing. If your car is ceramic coated, buy this I garente youll love it. Even if its not, this product does wonders for general car cleaning. I use it on the paint, glass, wheels, everything and it works great.

Amazing product. Car looks great. Easy to use. Doesn’t use a ton of water. 20-30 minutes to wash a car can’t be beat.

This stuff is great and well worth it. Goes a long way. Dilute to make a spray detailed and it will last a long time. Goes on nice and leaves a great shine.

Great product for my ceramic coated car

A little bit goes a long way. The product is concentrated so it is mixed with water. It sprays on and wipes off easily and leaves no residue.

I usually use Trinova dry was and wax which is a superb all around detailerfor your car, but recently I ceramic coated my car with Cquartz so I wanted to use there product in hopes of prolonging my cerami. Coating This dry wash is the best Ive used so far, Truely streak free, easy on easy off. I mixed it at a ratio 1:12. For exterior paint I believe its superior to all others of this category If mixed as I did it makes 3 gallons and 1 quart of ready to use product Which is a huge cost savings compared to buying a dry wash/wax at local Wal-Mart or parts store and a 100% better ferformance The bottle it comes in also has a sprayer included to convert it to a spray bottle once youve mixed up the concentrate in separate jugs. The only Con I have seen is I had the bottle sitting on my drill bit storage box and it stained the black finish which tells me that if paint it was applied to was delicate or doesnt have a good clear coat on it will definitely likely ruin it, this could be the strength at which I had mixed it Where the Trinova would be harmless. I still recommend it with the exception of a person should try it in a hidden spot first

Fantastic product. Im very happy with it. This is a great way to wash my car that I had a professional ceramic coat put on. This is all I will use now.

I had my car done with Expel and then Carpro CQ Quartz and the Echo2 product is all I have used on it since I had it done. I spray it on any spot of bird droppings or Tree Sap and use a couple of clean microfiber towels and it looks like new. The key is to use multiple microfiber towels one to wipe down the spray and spot and a second to buff the spot. I even use it to wipe down my interior. I mix it 1-15 and it works great

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.

Ive tried various brands (ONR, etc.) but was never satisfied since they only worked on paint that had recently been washed (e.g. excessive rain/dust/etc. on the paint is too for these products to be effective due to the wipe-up residue and scratching/marring left behind. They all required a ton of spraying and too much elbow grease. ECH20 on the other hand is phenominal! Even diluted 1:15 it can handle paint that hasnt been washed in weeks. There are limits of course (caked dirt/mud) but man, I have been so impressed with CarPro in general. A light misting and wipe will get nearly all of the surace contaminants in one shot and leaves zero scratches behind. Followed up by a second misting/wipe and then a buff with a finishing towel really gives a deep, flawless shine. Plus this stuff lasts forever. One bottle has lasted nearly 9 months and I am a religious weekly car washer (wiper?). It has lasted longer than the next 3 products I tried combined!
